No Candidates today (rest day) so a little puzzle from a friend and fellow engine chess fanatic! 😎 🤓 An engine game with a rather strong engine 🐟 playing White! White's best move please!

/3 White still had the massive g-pawn and a black king pinned to the back rank. Progress looked painfully slow for White - the white king was needed to help support the queen to the queening square - but Black could do very little with all those tempi! The king hid from all the checks! Black had to give up the queen for the pawn leaving White with a winning position a rook up. A glorious game - that's why I love running engine matches in any positions I analyse!

/2 Stockfish swapped off a pair of rooks and then started to move the white pieces in; Dragon kept on pushing the a-pawn! The first crisis came after 40.Nf6! 40...Qf8 41.Rd7+ Kc8 42.g7!! traps the black queen! So Black kept on pushing and queened the pawn to replace the captured queen on e8!

/1 So, the first move was the stunning 27.Qxh7!! After 27...Rxh7 28.hxg6+ Rxg6 29.Rxh7+ Rg7... we reached the main point of the sacrifice. White played 30.g6+ Ke8 31.Rah1. Black is paralysed on the kingside and White has various ways to try and increase the pressure but Black has some play too! ...a5 and ...b5 gave Black a passed a-pawn!

Stockfish 15.1 is out! As well as plenty of elo gains above Stockfish 15 (especially In Fischer Random / C960) the most salient feature is the new evaluation scheme. +1 now equates to a 50% chance of winning the game against an equal strength opponent! You can get it now from Stockfishchess.org

tcec-chess.com Leela a piece down but the black king is stuck in the centre and the black pieces are in disarray!

tcec-chess.com The games are pretty slow (6 hours each) but the tension is growing! Komodo going for a hugely risky but typical Najdorf break!

Some from Leela! I would have been very depressed with the black position (it almost looks resignable after 30.Rg1) but 30…g5!! and 32…Rc5 were amazing defensive moves. 30…g5 gets the bishop active on the long diagonal; and White doesn’t want to grab the exchange on c5 because Black’s bishop would then be mighty on the king diagonal! Amazing play!

TCEC-chess.com Sharp Sicilian up next for the Very long time control bonus (VVLTC) Looks scary for Black but with 6 hours+60seconds of thinking time available, Leela doesn’t look too worried!

2.5 hours of thinking for Stockfish already by move 19! Leela - just 1.5 hours of thinking so far - with a nice-looking position aiming for the g5-break on the kingside!

Revisiting a few of the most controversial / interesting SuFi openings via the Very VERY long time control bonus event between Leela, Stockfish and Dragon! Starting off with a Slav that was analysed in great detail in my book and Chessable course “The Silicon Road to Chess Improvement” Engines have 6 hours each per game with a 60 second increment!

tcec-chess.com/ Next up at the TCEC, we have a brief period of testing while 7-man tablebases are added to the engines' armoury thanks to a hefty amount of new storage! (previously only 6-man were used) After that we have a couple of events at a VERY VERY LONG time control (VVTLC) and then some bonus events, the nicest of which is a 4K bonus for engines smaller than 4096 bytes!

tcec-chess.com/ Game 100 also ends in a draw, after Leela misplayed a clearly winning position! That leaves Leela as the convincing winner by 55.5-45.5 (+24 -13 = 63) Congratulations to the Leela team, commiserations to the Komodo team and thanks to both for a very entertaining match!
