Spike 1.4 vs Houdini 4 Pro 64-bit - Sicilian Najdorf, English Attack

This is a game played between two chess engines, namely Spike 1.4 and Houdini 4 Pro 64-bit. The opening played between these two chess programs was the Sicilian Najdorf, English Attack. It was played with blitz time controls 3 minutes with a 1 second increment. The clock times change during the video, and give the viewer an indication of the time spent on each move.  What I found of particular interest in this game was the queen check on h4 that provoked g3. Since white also castled kingside, the earlier h-pawn advance allowed yet another meaning. Initially h5 was played to "restrict" white's kingside expansion with g4. However the g3 advance coupled with white's kingside castle allows black a secondary and "aggressive" intention with an h4 strike. Can black do without castling if g3 is provoked and white opts for a kingside castled position?

    Can you do Stockfish vs Houdini next?  And keep those soundtracks rolling.

    I am not sure, but I think white loses the knigth, may be after Ra8 (threatening to pin (Rh8), and white cant avoid the lose it (Kg1 Rh8 followed by Rg8, if N moves Rh8 check followed by Rg8)

    Why not take the last pawn of in the endgame? (as seen from whites perspective)

    wow.. the piece sac looked interesting at first sight but it shouldnt have been correct, black defended very well, and the endding a piece for 2 pawns looked winning for black but in practices it is not so easy, there are a lot of drawing tricks

    I really thought Spike had that one for most of the game. Very close

    Nice videos, like the soundtracks too :)

    One suggestion though. As houdini is the champion engine at present, it might be nice to see it's side of the board that houdini is playing (i.e. flipped board when houdini is playing black), as it is likely to be the winning side...

    Well of course Houdini wins! Thanks for the video, Jerry!
