My Games Against Chess.com Level 10 and some videos etc.
23. At last a win against chess.com 10. Yes! (First victory over chess.com level 10)
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.
25. An arduous victory against chess.com level 10 11-20-18 (Second win over chess.com level 10)
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.
This is an interesting video.
Not a defeat but a static position after 85 moves. I am playing black against Stockfish in this game to test Aman's openning trick. Openning tricks usually do not work against good players. You learn them only in order to avoid them. They will not help you win.
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.
Gruenfeld Defense: Russian, Smyslov, Main Line, 9...Nb6 10.Rd1 Nc6 11.d5 Ne5
1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.Qb3 dxc4 6.Qxc4 O-O 7.e4 Bg4 8.Be3 Nfd7 9.Qb3 Nb6 10.Rd1 Nc6 11.d5 Ne5
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.
Old Indian Defense -- See Game Below.
1.Nf3 Nf6 2.b3
King's Indian Defense
1.d4 Nf6 2.c4 g6
Tarrasch Defense: Symmetrical Variation
1.d4 d5 2.c4 e6 3.Nc3 c5 4.e3 Nf6 5.Nf3 Nc6
Black's attack failed, then just trading off pieces.
Queen's Pawn Opening: Horwitz Defense, 2.Bf4
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 but then trades off its bishop and gets lost game. You can't defend against rook with just a knight!
