Breaking News - 23.02.2025:       Well, here is another series of unofficial tours, reason as unofficial due       To mostly of played engines are not so close in strength to each other!       That's why (via these cond.) no way to see which own books are best..       And is it worth to work? spending so many efforts over? yes..because       Fun, learning, strength..is on plus these classic tours are more close to       Human like! E.g I've picked the ones which are close to GMs strength..       And organizing these kind of tours may help for future tours too..Btw,       Some may say: why not via NNUE? sorry, In short, if each time same:        TOO BORING!) at least for my side.. actually I assume for many too )       Btw, this kind of CS is hard to be organized, in fact, if these tours were        Easy...everyone would run it...right?) Meanwhile, why I say I like that?       For examples, exception that you need to download and install all etc.       All of the engines come with special settings...since many various eng       Settings are needed to be configured but as usual, I've done my best!       Besides some engines are not so stable..such as time forfeits etc. e.g       Arasan 15.1 (including older vers), Shredder 7 + v7.04 forfeits on time,       Sure not always but the mentioned Arasan eng versions are buggy but       In overall, it seems almost all stable..plus I noticed no any crash so far..       Note also that I still work over it.. but as next, I started with ones which       Are close to Fruit 2.1's engine strength..and in the next days, I hope to       Organize a newer tour, but before... I need to be 100% sure regarding        Which are those ones, actually I know many.. but 'm looking for more..)       E.g according to latest strength tests (with Unique book for all): Results      Junior 10.1 is stronger than Fruit 2.1 but in the current tour: Junior's own        Book is playing as serious role about why is rated much lower, weaker..       Yes..a lot of mysteries in our hobby..but you'll never know until you try..!       But I admit too that Fruit's own book is not so strong too..otherwise via       Better, an updated book I expect Fruit 2.1 to be in higher ranks..or other       Good example, Gogobello 1.3 is weaker than many engines, but 11th..       Reason? definitely its own strong book is helped..ok dear chess friends       That's all for now..thank you very much for your interest, see you later )
        Book + Engine Leader: Hiarcs 10 - Congratulations to Hiarcs team!        Note: Hiarcs 10 is played with a custom built book, based on GMs..
