Game 50 - enterprising play by Komodo, but drawn.

Post by Graham Banks »

GAME 50
As white, Komodo gives up the exchange with 10.Rxh5, to shatter black's kingside. Two of black's weak pawns there also fall to compensate for the exchange.
Both sides castle queenside and all seems to have quietened down until Komodo initiates play on the queenside with 35.c4. With the two black rooks able to switch their attention over there, it appears a big risk to take, but after much interesting play, the game ends in a draw.

Although 50 games is only a small sample, Houdini did show a small edge in this match and was a deserved winner.

Re: Game 33 - full board press eventually claims victory

Graham Banks wrote:GAME 33
In a Modern Defence, Houdini developed a full board press and eventually broke Komodo down to regain the match lead.
After a glut of draws early in the match, we've now had seven decisive games.
Houdini leads by 17.0-16.0 (4 wins and 3 losses).
Again game decided early after 11-12 moves :lol:

I agree Graham especially game 49 is a real beauty with the break up move 48 g4!! followed by hxg4 49 h5!

Re: Game 49 - Houdini takes out the match in style +6 =39 -4

Post by yurikvelo »

Graham Banks wrote:GAME 49
In a 2.Bg5 Dutch which seems to be going nowhere fast, Houdini uncorks 24.Nxd5, giving up a piece for two pawns.
This gives Houdini connected passers on the b and c files, with the possibility of picking up the weak black a-pawn to create a third.
After committing Komodo's defences to the queenside, Houdini then blasts the kingside open with 48.g4.
Komodo desperately tries to stave off disaster with 58....Rxc3, going into an endgame the exchange down, but Houdini is just too good and goes on to win.
Houdini has won the match by being first to win six games (+6 =39 -4), but I'll play the return game regardless.
