Komodo 8CPU v Houdini 8CPU Match (2 hours + 30 secs)

[Graham Banks]

GAME 17
In a Queens Fianchetto (1.c4 b6), Komodo opts to try and hold onto the offered doubled d-pawn to cramp Houdini's style. Houdini is able to equalise material easily enough through taking the a-pawn. Komodo then gives up a piece on the kingside for three pawns. However, the resulting endgame is level and Houdini does spectators a favour by liquidating into a tablebase draw. An interesting battle.
The match score is 8.5-8.5.

[Graham Banks]

GAME 18
There was less drama in the return encounter, although there were some clever touches in the way that pieces were exchanged. The endgame was always destined to be drawn and was played out to a repetition when only king and pawns remained.
The match score is 9.0-9.0.

[Graham Banks]

GAME 19
In a Kan Sicilian, Houdini's plan of challenging the advanced black queenside pawns leads to several exchanges and an early endgame. Although the eventual rook and knight ending looks quite double-edged to the human eye, both engines can see that it is drawn all the way through.

GAME 20
Houdini plays the opening line differently and all looks serene until it ignites some excitement with h4. Komodo's position looks loose and under threat, but it manages to defuse any possible danger by going into the endgame a pawn down, but with the draw always in hand.
The match score is 10.0-10.0.

GAME 21
1. Nc3 quickly transposes into a Caro-Kann. Houdini quickly eyes up the black kingside and castles on opposite sides. Komodo staves off any immediate danger and the queens come off. Although Houdini seems to have central control and a spatial advantage, in reality both sides see the game as pretty much equal from start to finish.
Another draw and the match score is 10.5-10.5.

GAME 22
The opening is much quieter in the return game of this line until a brief flurry of action on the queenside. Then everything calms down again, the queens and a pair of rooks come off, and another drawn endgame arises.
The match score stands at 11.0-11.0.

GAME 23
In a Sicilian Moscow variation, Komodo (as black) quickly gets itself into trouble. Castling queenside proves to be unhelpful and the king wanders back over to the kingside as Houdini overwhelms the queenside. The game is effectively over before move 20!
Houdini retakes the lead 12.0-11.0.

Interesting. 4. .. Bg4 is pretty common but safer is 4. .. Bd7.

7. g4 is almost a novelty - the only other game I could find with this was Anton-Guijarro-Korobov (see below), which was also a win by White (and quite an upset). Komodo castling queenside was very risky, but Korobov avoided this and lost anyway. So I think Black should deviate earlier.

Here are the stats for 4......Bd7 and 4.....Bg4 from the Chessbase online database.
The given percentage is for white.

GAME 24
Komodo played the opening differently (no g4) and obtained a positional edge. However, Houdini stood firm and eventually equalised. Most interest came in the bishop v knight ending, but both engines always saw it as drawn.
Houdini leads by 12.5-11.5.
