Houdini 3 vs ClusterRybka Game 4 ...

[Lavir]

Yep, I wrote that too in the 2nd edit

Btw I think Houdini would have won either without Ne6? in some way.

[Leto]

I don't think so Robert. Houdini now shows +3 in pondering.

If I had to play the game I would draw against strong opposition probably, but Houdini seems to have the path to victory clear.

EDIT: As for Ka1!, yes I noticed that move when it was made with the intention of Ba2. Houdini really plays these wonderful moves sometimes.

Because Rybka finally cracked and played 45...Ne6?
46.Bb1! is game over, but note that Rybka expected Kb1? after over 5 minutes thinking .

No I'm pretty sure black was dead even without 45...Ne6.

possible continuation after 45...Ne6:

This is despair in it's pure form

Even without 45...Ne6 black was dead. For example if 45...Qe6, then:

Somebody should call it the Rybka Blind Cluster

Seriously, wanting to play 46. Kb1?? is terrible.

It would have been funny to see Kasparov in 1997 watching this game.

[S.Taylor]

While I can see that white is clearly better, a full continuation to win easily the game I cannot see.

White has now played nearly 20 moves without finding a crack in Black's defense. I wouldn't be surprised to see this game end in a draw, unless Rybka fails under time pressure.

[d]4r3/3r3p/p4k1P/1p1qp1p1/5nR1/P1P1QP2/1PB5/K3R3 b - - 0 45

P.S. Note the nice 44.Ka1! threatening to bring the bishop to a2!

Actually I'm shocked because i agreed that black was active and ballanced enough to hold the draw, but needed to be very exacting.
Of COURSE he needed to keep his knight on that outpost.

Right, B to a2 looks like way round which i didn't notice

In similar positions,the knight is a major defender and must indeed be kept on it's post.....

The game is lost anyhow and moving the knight actually accelerated the rest of the chess drama.....

Ok, I think now we can stop the game, so that maybe renting time cost is cut to hopefully play other games (they are too interesting to stop now )

[Lavir]

Wow!!!

Wonderful game.

Some really good moves by Houdini. 16. Qc3!, 26. Qd5+! with the continuation 28.Qe4! and then 44. Ka1! with the intention of Bb1-Ba2.
