So it has a 80% chance for winning this game, according to what Robert mentioned.
Where did you see that?
80% is for a +1.0 advantage against an equal opponent at blitz TC.

Yes 1 - 0 for sure. I have feeling, that H3 1CPU will be enough for this Cluster 8-) Somebody has really paid for use Rybka Cluster!?

16.Qc3! appeared to be a very good unexpected move.
The Rybka eval dropped by 0.3.
When Houdini starts sacking pawns, all is well :).

26.Qd5+ is another unexpected move (instead of Bd3), Houdini gives +1.46.

Houdini +1.70, Rybka Clu +0.80 (for the cluster Qd5 was a worse move than Bd3).

Who will be right?

We accept bets.

EDIT: Obviously Rybka was wrong.

Or there will be a miracle or this will be another loss for the Cluster (RIP).

Houdini played very very well.

The current position after 31.h5 g5.

[d]5r2/3r3p/p1n1qk2/1p2p1pP/4Q3/P2B1P2/1PP5/1K1R3R w - - 0 31
+1.80 according to Houdini, +1.60 according to Rybka.
In the main line Black doesn't lose any material for at least 10 moves (20 plies), it's really incredible that both evaluations favor White so much.

Yet another time, this game has shown that the Rybka Cluster evaluation is always one step back from the one of Houdini.

Simply speaking Houdini sees things much earlier than Rybka can, and it even sees things that Rybka cannot either grasp (and "catch" only later).
