Nobody knows why, this is really super-human chess.

Not because of passed Pawn? (issue has been tipping the ballance)

Yes, but the passed e-pawn was already there a move ago.
Why all of the sudden Kg3 "wins" the game is unclear to me - and also the Rybka Cluster didn't see it coming.

We can all see that it's a good position for white, but it's fascinating to see Houdini actually win it, increasing its advantage move by move.

No, actually it is enough easy, IMO, to understand why the jump in the evaluation (again).

The second rook was traded, now the passed pawn becomes like a full queen in evaluation (since it cannot be stopped no more).

The rooks in the board where the only things stopping the advance (and with it the threats along), so after the first, and then the second were gone, both had a jump (one naturally higher than the other) in the eval.

Probably H3, until the second rook was on the board, calculated manuvers that could blockade the pawn a little longer; after the move of Rybka (and much probably an error for H3) there's was no more that "problem".

You play better than the Rybka Cluster or the Komodo 5 version that is kibitzing the game on the https://secure.join.me/181-416-514 broadcast.

Many issues came up. But they don't always see it all from far back.

LOL, naturally not.

After it is easy to understand. The problem is understanding it before.

I'm just making guesses. The evals had a jump both times just before a trade of rooks, and it's a well known rule that in an endgame rooks can block a passer while with a queen only it's impossible.

Why Komodo and the Rybka cluster didn't see it coming (both times)? This I don't know, but evidently something was there, don't you think? It happened... so it's not a matter of making guesses, since it's a fact.

Yep,typical Robert......

Another stab in the back of Komodo and it's team whenever you get the chance.....

Pathetic to say the least.....
