Houdini 6.03 64-bit 8CPU v Stockfish 181117 64-bit 8CPU

[Graham Banks]

GAME 26

Houdini's passed b-pawn out of the opening never gets the chance to become a threat, as Stockfish initiates exchanges that lead into a drawn rook and pawns ending. Stockfish holds on to its slender one point lead in the match 13.5-12.5 (three wins against two).

GAME 28

It looked as though Houdini might have winning chances after it cleverly gained control on the queenside, creating a passed pawn in the process. However, Stockfish was able to defuse the danger and salvage a draw. Stockfish leads by 14.5-13.5 (three wins to two).

GAME 29

Stockfish slowly ratchets up queenside pressure against the the Dutch, before a clever exchange sacrifice sets up a breakthrough on the kingside that leads to victory. A superb win that sees Stockfish extend its lead to 15.5-13.5 (four wins to two).

GAME 30

In contrast to the previous game, Stockfish plays actively to defuse any danger on the queenside. Houdini can't see any way of making progress and opts to give up a bishop to force a perpetual check. Stockfish leads by 16.0-14.0 (four wins to two).

What a great tournament Meanwhile the TCEC continues.

[Nordlandia]

@Graham: are you willing to experiment with ponder on your dual cpu xeon.

Each engine get allocated one Xeon for whole game.

Is will be interesting to see whether 60-70% ponder accuracy outweights splitting total cores.

Consider this when you have time.

GAME 31

Houdini got rid of white's e5 knight at the expense of being saddled with an IQP and queenside pawn minority. Any pressure for a long while was from Stockfish, but Houdini's position held, After most pieces came off, Stockfish went into a rook and pawns ending a pawn ahead, but it was always going to be drawn. Stockfish leads by 16.5-14.5 (four wins to two).

GAME 32

Houdini looked for kingside expansion, but Stockfish had enough counter-pressure in the centre to prevent any danger. When Houdini's weak d-pawn was captured, the ensuing exchanges led into a queen and minor piece ending. A perpetual check concluded the game shortly afterwards. Stockfish leads by 17.0-15.0 (four wins to two).

GAME 33

As black, Houdini opens up the position with 15...c5, but again ends up with an IQP in return for some queenside activity. However, as trades occur, the problem of this pawn is solved and we go into an even queen and minor piece ending. After the final minor pieces are exchanged, Stockfish is happy to take a perpetual check. Stockfish leads by 17.5-15.5 (four wins to two).
