[BB+]

Rybka really overestimated its chances against Equinox in the same colour B ending, though in some sense heading into the endgame (at move 31) was when the die was cast. As for Houdini, if drawing with Black was the goal, it was never really in trouble. The endgame after 11... Bxf2+ does not lend White much hope for a win.

Incidentally, Game 2.2 (Komodo-Shredder?) is not showing up in the web "Please select a game" for me (though 3.16 does).

Komodo - Shredder has mysteriously disappeared from all PGN files, like it never existed.

It can, however, be found on ChessBomb (though without engine info like depth, eval etc).

Houdini cleverly avoided the draw rules and went on to win.
Gull had some odd time management, but the main thing is that the snatched pawn held up.

I really think Chiron erred on the first non-book move (9. a4) against Vitruvius. Following up with g4 a couple moves later, and White's king had no home. It is difficult to combine systems like that. Vitruvius did well to keep Black's king in the centre, where it seems safest.

Houdini-Rybka had a lot of back-and-forth manuevering with a minimal White advantage, but eventually Black's weak squares and pawns, combined with White's two bishops when the position opened, proved sufficient. Rybka almost seems to have "missed" Bd6+ on move 56, as the score changed significantly. Maybe time trouble played a role, with Black down to 30-45 seconds or so?
