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

[Graham Banks]

GAME 22

A fairly uneventful draw. Stockfish set up a solid pawn structure and found d5 to be a strong outpost for its knight. Houdini traded its bishop for the d5 knight late in the game, hoping to create chances on the kingside, but there was nothing there.

GAME 23

Houdini obtains a passed pawn on c4 during the middlegame, but again can't gain further advantage against the robust Stockfish position. Stockfish later breaks open the position on the kingside with 40. g5 and 44. f4. Exchanges occur leading to a fairly interesting double rooks and pawns endgame, which ends in a draw. Stockfish leads by 12.0-11.0 (three wins against two).

GAME 24

Stockfish looks to have an early spatial edge, but Houdini counters with active rook play on the queenside. Stockfish then decides to end the game quickly, sacrificing a rook on g2 to force a perpetual check. Stockfish leads by 12.5-11.5 (three wins to two).

GAME 25

After all of the rooks come off via the e-file, a queen and minor pieces ending eventuates. It is always drawish and Houdini finds a nice way to accelerate the end. Stockfish leads by 13.0-12.0 (three wins to two).

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).
