Game 4 Rybka vs Zappa

[AdminX]

Looks like the fish will bite back again. Due to problems with DGT board, this is not going out on the website. Here is the game game as posted on Playchess so far. Looks like a storm is brewing, a pawn storm.

My Fruit shows +1.0 , which is sad enough; although Zappa is not easy to crack afaik

UPDATE: Due to technical problems, I'm not 100% sure about this updated game score.

Looks like it's heading for a draw. Black has a fortress and white cant see a way through.

That has been the interesting thing (for me) for the past few moves.
I thought surely Rybka knows how to conclude a "won" game, but it is up against a strong opponent. Or? maybe it's NOT a won game, even against a weaker opponent than Zappa?
I know one thing, _I_ do not know how to win these positions against a strong opponent.

OH! that's looking good for Rybka (at quick glance)

It flatters to deceive

Not any more! I think the diagram I was talking about was a mistake, and now it was edited corrected. wow!

[S.Taylor]

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 what the score is, but for sure, the next thing to hope for is game 5.

On my C2D Laptop Glaurung 1.2.1 MP finds 51.Qe1! in under a minute
And I think 60. f5 was forced, if you protect the pawn with the king, black plays something like 60...Rh6, and e5 loses the pawn. You have to go back with king to d4, then comes Rf6.
Me wants a Zappa...
