It is me against Boris! Never a boring game. I am white.
Also below are 106 games (starting with game 23) I won against chess.com level 10, which is much harder than Sparkchess.com's Boris. Now I am playing lichess.org SF8, with 14 wins so far. Goto game 85. Lichess is my favorite to play now (no move take backs to make it realistic + it stores your game results so you can't abandon a game!).
1. Boris 10-27-18 (won middle game)
6. A draw against Claire :(
Sacrifice fell short but able to draw - though down a N.
(Playing "whatever" opennings today.)
Boris just played terrible in this game.
Forgot openning above but able to win in B vs N end game.
White wins the exchange and the game.
Boris managed a perpetual check draw. Not a good opening.
Boris trades queens on move 24 but lets me have passed pawns.
I trick Boris into openning up his king's file to win a pawn.
Guardian News: Magnus missed the win today
So many errors! Black could have won.
Boris thought a long time then sacrificed its Q (???) without any mate threat.
Strategy: take N to get doubled Ps on black's KR file, move 2 N there to drive Q away, then launch attack with Rs, Q, and N. Having developed P chain on Q side to slow counterattack. They must have improved the Boris program tonight as it thinking a few seconds when in difficulty. Harder to win tonight. At one point it flashed an red AI error message, so seems they were tweaking it.

If you look at the checkmate threat it missed in its analysis you will understand that engines have trouble with dark matter.
Guru crashed my Chromebook twice trying to escape the loss but Chrome recovered the game each time.
Working now Trying to defeat Chess.com level 10. Have a game now where I opened up K side with N sacrifice and also trapped a Black B to make the game even, but impossible to find any advantage for attacks. All attacks just decrease score. A lot of energy and not much fun just to get an even position. Level 10 is a very hard nut to crack as it uses Stockfish engine. But will try again tonight. 11-14-18.
Tonight I will try level 10 again.
Managed to have an advanced N, so now it is a 2 N vs. 2 B game. Suspect it will trade off a B for my N at some point. May reinforce advanced N with the other one. Then B would have no way to get rid of it. What is best move for white now?
Tried to duplicate this but Chess.com did not play the same moves.
Best to play the London openning against Chess.com 10. Gives most even game for the human player.
White was up a rook but black draws by repetition. Notice that it cares little for king protection.
No mistakes, perfectly symmetrical finish.
I rejected a Q trade. I had tiny advantage but with 2 Qs black easily drew with perpetual check.
It is difficult to actually win against chess.com 10 since it does not make blunders or tactical mistakes. It still makes strategic mistakes for tactical advantage, such as trading a R for a B, in which case you may be able to win!
Went back and changed a move in game 22 to get a winning advantage. In the end, black was reduced to a King. I love to take all the pieces.
Caruana played R d1 to prepare for Nc4. Game ended in draw. Caruana is not risking enough to win.
A drawn game. But will try again to win.
Wow, 132 moves but victory at last! The key to avoiding a draw was to exchange the light square bishops in the end game. If black is allowed to keep the B pair, it is impossible to win because of perpetual check and the checkmate threat by black. Final positioning to queen the pawn probably could have been more efficient, but I figured it out in the end. A win is a win after all.
On move 28, black can't take the bishop because of a discovered check. Cute. On move 34 black is forced to trade his rook for a bishop. Always dangerous to send your rooks downstream. On move 45, I trade Qs to use my endgame rook advantage. On move 67, I advance a pawn and sacrifice another to open up the board. On move 76. I trade white bishops to get rid of black's B-pair threat. The decisive step to preventing the draw.
Main lesson form game 25 is: do not let your opponent keep a B-pair. You cannot defeat it even if you have a R to B advantage. Try to work the game down to your R and a pawn against the computer's B . Then you can win.
Why not just let chess.com level 10 play itself and see who wins? Have tried this, but so far, it always results in a draw. Stockfish will never show you a win! This is probably because it uses the same logic for both sides. This is also the reason why you cannot improve much by just playing against yourself. You have to play other people, other programs. You have to figure out the asymetircal winning moves for yourself! Sort of like Rubik's cube, only harder.
A good exercise is to take a drawn computer game and turn it into a win. Where does the chess master intervene?
To create a win, you have to take a risk. You have to create a slightly asymmetrical position, which may even give you a slight negative score temporarily.
If you get a large enough intitial advantage, it will usually grow if you avoid errors from then on. So you will see your positive score increase. If you are losing, the negative score will grow, so just stop playing -- it is a lost game.
Two different chess engines are more likely to result in one side losing, but those games are often very strange looking. They are not necessarily great games. Watch and decide:
Looks like this will be a drawn game and match.
An interesting game, when Magnus Carlsen was only 13 years old.
Stockfish avoids my opening trap with 6. ... Nec6.
No way this line can be anything but a draw.
Traded rooks and used split pawns to win the end game with a King attack. Stockfish can't count.
Magnus tries for a win with black but result is another draw. A good game.
Played against the Sicilian Defense: Kan, Knight Variation, Wing Attack, 6.Bd3 Qb6 7.Nb3
Keys to winning this game: exchange dark square bishops (can never win endgame if black has B-pair), 18. Be7, using knights and pawns to close the game restricting black to 1/3 of board, opening up black's defense with triple threat on black knight with 52. Qc1 forcing black to give up exchange on 52. ... Rb6, capturing passed pawn on 65 Qb4, getting a protected knight entrenched on 67. Nf6, so it was a forced mate at the end, white winning! When you replay it, it looks easy, but it was difficult to figure out how to open up the Q side. Playing a high level Stockfish is very educational.
Could not get a win in this game, try as I might. Black's dark square bishop just stifles my endgame. Stockfish finally trades B's when it realizes it is one step ahead in the pawn race. And so poof, two Kings left on the board.
Revisted the French Defense to get a win for white. 12. c3 was needed to hold on to the center pawn. 23. fc3 takes with the pawn because all you need is 2 pawn on the king side when black has a double pawn. 2 can stop 3. Also I wanted to avoid R getting pinned. 30. ed4 and the K's pawn moves all the way to the Q side! 35. g4, always advance your pawns as far as you can in the end game. 46. Kb4 and the passed pawn is ready to push. 52. Kd5, now head for the king side to take all black's remaining pawns and win convincingly! Easy peasy. Don't take Stockfish's advice in the end game. It will more often than not give away your pawns and then you can only get a draw. You can consider it's recommendation but think for yourself!
Played several variations of this, all ending in a draw. White basically has a weak opening and so needs to exchange everything to get a draw. Magnus needs to come up with a much stronger opening next time.
World champions play for draws and it is considered great. A least I was playing for a win here. Maybe this game could be turned into a win with another try. Often you can try again with same strategy and get a win.
I pushed all the pawns to open up the board. King's Indian game. Got bishop ahead and used King, Bishop, and Rook against a Rook to push a pawn to victory. Black's strategy was to collect pawns and had a massive pawn advantage, but they all fell in the end. Stockfish made a mistake in end game here as alternative endings lead to a draw.
Interesting to see how to checkmate with Rook and Knight against a Bishop. Uses mate threat to capture the bishop.
An interesting game. 6. d5 is important to grab a lot of space. 8, Bg5 is a cute maneuver to tempt black to open up K-side pawns, never mind eventual capture of B on g3. Always take with h pawn. 36 ... Rf8 not clever considering good position of other white rook to take pawns. Major flaw for black is his K way of on the side, away from the pawn action! So eventually white promotes.
Not a defeat but a static position after 85 moves.
Black wins, but not so easily. There were 170 moves to checkmate. Magnus' offer of a draw was thus justified. Even though slightly ahead, Magnus had no clear path to winning. I took some of Stockfish suggestions for black, but if I took all as it would have been a draw.
Stockfish always draws when playing itself in a near even position, less than a 1.5 point advantage. If the advantage is pure material, with a 3 point advantage, such as queen vs 2 bishops, Stockfish may still draw playing itself. Most people rate a N and B as both 3. But if you have a bishop pair, that pair is probably worth 7.5, just a little less than a queen, 9. In the end game it is nearly impossible to win instead of draw if your opponent has a B-pair. By the same token, a N pair is probably worth 6.5 as they can protect each other, while a B and N is worth 6.
In this WCC game 12, Fabiano was running out of time, only 8 minutes for 9 moves, and Magnus was clearly thinking on both players time. Magnus is a much faster thinker and is confident of winning the tie break. Perhaps Magnus did not want to see Fabiano blunder because of time. Magnus is a nice guy and they are not enemies. Some people are rooting for Fabiano because he is an American. I have no such bias. I do not consider country of origin, only playing ability and courteous behavior .
Ready for another draw? https://www.chess.com/computer-chess-championship
Arriving at same pieces left over now as my game 35 above. 4:58pm EST 11-27-18
Now it looks drawn. Ethereal did not know how to win the ending. 5:15 pm
Buth stockfish trying for a win. But can it take three connected pawns with a rook?
Still a draw. 5:24 pm. Draw by repetition called 5:26 pm.
One, Two, Three...Magnus is still the champ!
So drawing the twelves games was a rational choice, as Magnus knew he could easily win the rapids. Better not to risk too much, and you do need to take risks to win at chess when your opponent is very good. Winning is everything after all if you are world champion. You do not really want to risk your title just to please the critics.
2012 CBS video: World Chess Champion Magnus Carlsen stays number one
Computer misjudges that pawn advantage will allow it to give u a piece. on 24. ... Rc4. However, even if the King takes the bishop, white still wins as below.
So this is a pretty solid won game. A good opening to play against a strong opponent if you are looking for more than a draw. Also, don't count your pawns as remaining until down to rooks.
I have been playing chess.com tactics lately, which is a lot of fun. Very tricky. Counts as incorrect if your checkmate solution is not exactly what they want. So have to figure out what they want to not get tricked.
Queen's Pawn Opening: Mason Attack. Ending is completely equal with the two kings fending off pawn attacks on opposite sides of the board. Shows how king can defend against two advancing pawns.
Hey! This stuff is not easy. But it is a lot of fun. Started with Queen Pawn Mason Attack but that was just the beginning.
Winning the end game with an extra pawn. Keep your extra pawn. The moves chess.com suggests for you seem not quite as good as what it plays against you. It gives up your pawns too easily for example. It also often suggests you retreat. The winning moves you have to figure out for yourself. Key here was pushing the "h" pawn all the way down for a mate threat with the queen. When the computer plays itself, it is always a draw. Also, did not castle as Q is usually traded. Castling just makes your K a nice target. Computers often don't castle.
In this end game the knight proved superior to the bishop. I used a straightforward strategy here of putting all my pawns on a dark squares and using the K and N to destroy all the black pawns. A beautiful ending!
A more solid opening but long end game. Black made a mistake on move 43. ... g5 otherwise would have been a draw,
This game shows the futility of trying to win if your opponent has a B-pair in the end game. Your King is immobilized.
No win found here. You can always draw by taking computer suggestions. But some games can only draw, there being no win possible. To win you do have to find at least a pawn advantage with a good position. The computer will not do this for you of course.
A very interesting game. Old Indian Defense. Don't trade automatically if you want to win! After winning the pawn on 41. Qxc5, white just wants to trade queens. As much fun as recent GM games.
Kasparov resigned after 46. a6
I let Chess.com 10 finish the game to see if Gary really would have lost. He would have. Was a lost games several moves earlier. Gary was too passive in this game and kept repositioning his knights. Once white got into the backfield, it was all over.
Analysis said I made 2 inaccuracies and 1 blunder! But I easily won. Very easy game in fact. Computer says it made no mistakes, but then why did it lose? I would say losing a pawn is a mistake. Stockfish does not care enough about its pawns. So go after them! I think 28. .. c5, pushing its pawn 2 spaces only to trade it was a mistake for black. It should have kept more pawns on the dark squares as it had a dark square bishop. White then ate the pawns on the light squares with its light square bishop.
Kasparov resigned after 19 moves. This shows the continuation to checkmate with Stockfish 9 playing both sides. Obviously Gary was trying to be too fancy here.
INACCURACY (+1.70) A better move was 7... Bd6
11. Bf4 b5
INACCURACY (+2.24) A better move was 11... Nh7
So Kasparov should have won if he had played a little bit more accurately. Players have obviously improved since 1997 due to practice with computer chess engines.
If you take the program suggestions, you can only draw as it only shows you good moves, not the winning ones.
Black trades Queen for 2 Rooks. White trades Queen for Rook, but ends up with 2 Queens to checkmate. Interesting game.

White wins 47%, Black 22.9%
Unorthodox opening but hacked through the middle game to a checkmate.
Preemptive B g6 causes black to advance pawns weakening king side and launching futile attack with Q that backfires, losing pawns.
An interesting opening. The queen comes out.
English Opening Symmetrical Variation
King's Indian Defense: Petrosian Variation. Ended in checkmate without pawn promotion. I prefer to open with c4 rather than nf3.

Black's attack failed, then just trading off pieces.
Queen's Pawn Opening: Horwitz Defense, 1.d4 e6 2.Bf4
Won the ending with equal pieces. A simple stratagem that Stockfish could not fathom.
Stockfish gives up rook exchange for protected passed pawn. The key to winning is 11. c5 rather than trading off pawns in the center. The idea of this opening is to command the center.
1.e4 c5 2.c3
16. f4 and 17. f5 were key moves to pursue the advantage
Also, having a doubled pawns leads to win in the end game.
When Black loses the analysis always finds lots of errors.
Queens'Pawn Opening: English Defense 3. e4 Bb7 4. Bd3
This looks like fun: Simulation: Alexandra Botez
Black started losing when it gave up its white bishop, having previously traded off its queen. If you trade off your queen, you need to keep both bishops.
This game the computer lost because it gave up the knights protecting the King side and the other knight was not protecting either. An unforced error. Really kind of beginner's error.
In this game Black was too aggressive and traded off pieces but also gave up pawns doing so, ending up two pawns down in the end game.
Black bishop should not have attacked the rook.
Made a successful kingside sacrifice attack. You really need to keep enough pieces there to ward this kind of attack off! The Bobby Fischer simulator is the most interesting one on Chess DB. Worth playing for its educational benefit.
(The Chess DB database messed up and lost my game.)
An interesting game in which white has only pawns at the end against a bishop but wins.
Yay! (Playing black here.)
This was revenge match after a computer lockup in which lichess declared I had resigned! So I replayed this Reversed Sicilian for a solid victory!
Supposedly rated at 2900 but easier to beat than the lichess program rated at 2600. Useful for studying this opening, the Benko Gambit.
Not an easy game but wins in the end with a checkmate. Leveraging the pawns.
Video: Tal beats Fischer 1959
A very artistic checkmate.
11. ne5 is what lichess SF10 said was stronger. Played it against the lichess analyzer and still won. Interesting that another analysis of this game finds lots of fault with SF10's previous recommendations on the prior analysis. It is never happy with a loss of course.
This more aggressive opening is good to avoid a draw. Finger slipped with a m1#, Rats! So I had to do checkmate a longer way. Lucky no stalemate.
It played same defense as game 95 but with a variation that still lost handily.
Analysis of this c4 opening finds no errors on either side.
Not as easy but it won.
Using lichess analyzer suggestions resulted in a draw. Now I will go back and play it myself to see if I can win. lichess says neither side made any mistakes.
Showing that you should never give up your c4 pawn for no reason. Accumulate a pair of pawns for the end game.
Venturing your queen out too early can be deadly.
This is the variation I really wanted to win!
No errors for white, lots for black, but it always finds errors when it loses.
Now the score with lichess is 13-7-9 so I have won almost twice as often as losing to SF8.
Notice that this game is harder to win because i am basically playing against SF10, and I had to figure out how to avoid the draw by myself.
Analysis of this variation has lichess complaining that another move 17 was inferior, but playing that out leads to a draw by repetition, so any change is more or less a new pretty even game. Can't iterate a game to death. Just have to play a new game. Take it for what it is.
If you keep hitting the spacebar, the lichess analyzer shows how this game could have been a draw. But start at move 15 and can win for Ray. I admire those who can play good chess in real time, with real people.
Won in 140 moves. Using the spacebar on move 16 gives a win in 131 moves, so not much difference. My game is more interesting I think. Says I made one mistake on move 40. Taking SF10 alternative produces a win in 111 moves.
So yeah! Once again, hitting space bar after move 14 shows a won game for white. Games are won often by move 14 or 15, even before any errors are detected by the engines.
Used lichess analysis (SF10 ) this game after it was clearly a draw to turn it into a win for white.

English Opening: King's English Variation
Black can respond to the English Opening (1.c4) by placing a pawn on the strong central square e5.
This gives Black a good central presence and prepares to develop the Bf8.
Pros: Black creates a good center - Takes control of d4 - Rapid development
Cons: Results in a Sicilian, down a tempo - Allows White to dominate the queenside
I like the way this game was played, very strong for white, pretty. The lichess analysis suggestions lead to a game that is more likely to draw. I want to win! To beat the computer!
Exchanging pawns seems to do better. A stronger game.
Not a great opening or game. White wins on Black errors.
Should have played 4. Be2. Could have won.
A much better game this time. More solid.
Find the checkmate!
A solid game for white.
The pawn on d5 eventually queens! Very funny.
