Game 4 Rybka vs Zappa

[Uri Blass]

Oh no! i probably also made a mistake in thinking it interesting. No, there was never even a question of it not being a draw. (I had my own oversights too).
I don't know the score is, but the next thing to hope for is game 5.

It seems that rybka missed a win.

Zappa is simply better than rybka in the relevant position because zappa could see in the game how rybka could win when rybka could not see it.

Zappa expected 52.Qe1 and has a drop in the evaluation but rybka could not see it.

Current Position looks like the storm is over:

[d]3Q4/5r1k/7r/3P4/3KP1b1/8/8/8 w - - 0 127

[Martin Thoresen]

Looks pretty drawish.

I hope Zappa manage to draw this.

[AdminX]

Oh boy! Long but good!

[d]1Q6/3r4/3Pb1k1/4P3/7r/4K3/8/8 w - - 0 132

[George Tsavdaris]

Oh boy! Long but good!

Rybka would lose.
That's the result of being greedy....
Rybka should stay with the draw and not give its Pawns trying to win....

[d]8/8/3Pb3/2K1P1Q1/1r3r2/8/5k2/8 w - - 0 142

[Uri Blass]

I also hope that it is a draw
Based on the scores Zappa may even win this game and I hope it does not going to happen.

I finally managed to log on to PlayChess just in time to watch Zappa win!!

Hey George, I don´t believe that Zappa wins this game. I was on Playchess and I remember
that you are there. Some time after the problems with the game, I hosed to leave the room,
and only now I am know the result. When I leave the room I was certain that Rybka would win.
What a game, this is good for computer chess!
