Game 920/1620

A B48,  Sicilian Taimanov has caused some difficulties for engines in this tournament and Houdini found itself in a curious position here. Out of the opening, Houdini played 12.Na4 forcing exchanges leading to a material imbalance that in hindsight may not have been the best strategy against Komodo. With equal pawns, Houdini had its Queen; Komodo two Knights and a Bishop for the Queen trade. Komodo has done well with material imbalance games in the past and so it was here too.

With Komodo castled short, Houdini embarked on a King's side pawn attack but to no avail and its King defence looked fragile. Houdini's Rook on d6 was on offer but at the expense of giving Houdini a potentially strong passed pawn. After securing its position, Komodo exchanged its Black bishop for the Rook but now with just Queen and Rook did Houdini have enough material to force the C and D passed pawns? It looked unlikely.

With 41..Na4, Komodo had effectively disable Houdini's Queen although it was stuck at a5 supporting the b4 pawn because by playing the supporting a3, the Queen was still restrained. With Houdini in a hapless position it gave up its Rook for Knight to allow its Queen to escape from the b4 tie but too late. Komodo had now created its own King's side passed pawns. Game over.

Komodo performed very well during TCEC as regards material imbalances.
There were queen for minors exchanges that had everyone swooning.
Some of the swaps were a bit distant so that they even looked like queen sacrifices until the compensation became clear.
Komodo also performed well in those games.

Interesting game but there are no alternatives to 12.Na4.

Where White went wrong later was with 20.Be4?! and the useless King-side attack. In this position
r1b1nrk1/1pbp1ppp/p3p1n1/4P3/5PP1/5B1P/PPP5/3RQR1K w - - 0 20


20.Bg2! would have been better, keeping the King-side together and getting play in the center and on the Queen-side.

Thanks for looking at this game. I agree with your comments. Houdini 6 tends to be quite aggressive and often its attacks come off but here Komodo seemed to have something extra enabling it to take advantage although perhaps I should play the game with reversed colours for comparison. I may do that when the tournament is complete.

Komodo excels in queen vs minor imbalances.

Thanks for comments. Yes that is the impression I get too. Interesting analysis links where it suggests Komodo was the more precise!

Three minor pieces is usually better than queen, particularly if the bishop pair is present on the board.
