The longest game so far and in this match I have been stopping the game at the point of mate announcements. In this game the Caro-Kann, Spassky variation was played but it was not until almost exactly half way through the game did TheKing start to gain and finally win. In fact, at times Maia was playing much better and should have won.
In the following position Maia had just played 21…Rb8?!
The position is dangerous for TheKing with Maia’s pieces lining up for an attack on its King. However, Maia’s move was not the best. 21…Ba3 would have been the better attack, but nonetheless, TheKing needs to be very careful. The Pawn on b2 and Queen on c2 are the main defence against Maia’s onslaught. TheKing moved 22.Ne5?! Better would have been to consider King safety with 22.Ka1
Play continued with 22…Nxe5 23.dxe5 and although Black is down a pawn is in a much better position:
Later on White had just moved 38.Kc2 and Maia with the Black pieces was 2 pawns down but had again achieved a better position after having an advantage and losing it a few moves back! However, as I often say it’s easy for strong PC engines to identify good and bad positions, in this case DH15.3 was looking 23 ply ahead. TheKing with 30 average 30 seconds was achieving around 10 ply, and Maia was limited to 6 ply although had it’s Neural data to assist. Here is the position:
DH15 gives Black an evaluation of around 2.8 over TheKing. Here, Maia played 38…Qc6+? DH15 gives this position an eval of 0.00 (at ply 28). Play then continue with 39.Bc3 and White would not mind exchanging Rooks to ease the pressure. 39…Rc5 Black wants to keep the Rook! 40.Rd8+ and the game is level. I think for Maia to see the full implications and I assume the Neural data was not good enough, it’s 6 ply search was just not enough to see the better move of 38…Bf8 allowing the move Na3+ to follow. So now the game is level until move 43 when TheKing started to get the advantage. Even then it also made poor choices and levelled the playing field before finally kicking into action, also aided by a blunder from Maia at move 73:
TheKing had just moved 73.Kf3 and Maia replied 73…Qc2?? Had it correctly evaluated the position after 6 ply search that actually followed it would have found the exchange of Queens and Whites’s Pawn on e5 to be a winning combination. I think this is where TheKing’s greater search depth coupled with its programmed knowledge is superior to Maia’s more limited fixed 6 ply, and obviously its neural data is inadequate in such positions. That being said, we can see TheKing is not always playing so well and Maia put up a pretty good fight for half the game. Just imagine Maia being able to look further ahead, the result could well be quite different. Anyway, at move 87 TheKing announced mate in 10.
Current score 4 ½ - ½ to TheKing
