Featured is a game from round 6 of the Top Chess Engine Championship, Season 16 between Leela Chess Zero (LCZero) v0.22.0-nT40B.4-160 and KomodoMCTS (Monte Carlo Tree Search) 2381.00. There are many instructional moments in this game out of a Slav Defense, Quiet (Slow) variation. In it, white doesn't deploy the bad bishop outside the pawn chain, whereas black does. Eventually KomodoMCTS is successful in exchanging the bad bishop for white's good bishop. In the process, white achieves a slight queenside space advantage, and a black pawn to bite at on g6. What follows as white pursues a kingside attack is a star idea that I have only ever previously seen surface with a knight taking center stage.

@@ninepoints5932 Rh7 after Ke6 isn't mate for several reasons, most of them having to do with the illegality of the king moving several squares to take his own pawn. Kf7 is arguably better because it is legal and probably what you meant, but best of all is resignation.

17:17 If king takes rook, then bishop f6 check. If king moves to h7 then rook check mate after king moves to g8. If king moves to g8 first, then rook to h1 preparing to go to h8. king can run to f8 but it would be too late and rook h8 checkmate.

Amazing game! I think one thing you didn't mention is that black has his pieces concentrated on the queenside while white managed to open the kingside and line up all his pieces to attack the king. It seems to me that black put too much weight on material and went for those pawns while white focused on attacking the king with a long term strategy.

@bennieblanks5129 4 года назад

I saw the combination but I continued staring at the screen for another 20 minutes assuming I was missing something. I was convinced that if I saw it that a super computer would never have found itself in that situation. I guess I underestimated just how strong Leela is. Let's just hope it sticks to chess. The last thing we need is it taking an interest in utilitarianism. Death by ethical human purge isn't my idea of a good time.

Jason Anno almost. You have the right idea. But if you on Kh8 play Rh1+ the king can also go to g7. Instead you first play Bf6+, Kg8, Rh1 with mate on h8 next move. If black instead of Kh8 plays f6 then Rh1, fxg5, Rh1h7+, Kf6, Rh8f8#. Hope that helps :) Great lesson as always Jerry.
