What was the last white´s move?.

Bh7? Followed by ...g6.

It could be, but in that case the draw is over for white....

[George Tsavdaris]

with a little faster

What exactly?

Thanks but what about the initial position?
Does it find 1.Bg6+!! ?

regards Anton

Thanks.
So in the modified position it does 19 minutes while in the original(from the game) one it does 3 minutes.

6.3 times longer! Thank you for the analysis, i tried to make the position harder but i didn't think it would become so much harder.

And what hardware did you use for the analysis?

[George Tsavdaris]

Strange. Crafty finds it in 5 minutes:

Why do you think it's strange?

I guess I've come to expect that Houdini solves all problems very quickly. But having now tried several other engines, I am coming to the conclusion that Crafty was either especially smart or especially SMP-lucky.

[EDIT] See this: http://www.talkchess.com/forum/viewtopi ... 25&t=37265

He analyzed wrong position. See my reply there.
Perhaps of course Houdini on my position also solves it fast in his hardware, but we will see.

His hardware cannot be that fast. My i7 920 solves it alot faster.

Thanks for the analysis, but what hardware did you use for the analysis?

[Uri Blass]

I am disappointed by houdini.

I read that rybka cluster solved position number 1 and 2 relatively fast(near 5 minutes)

I hoped to see houdini1.5 4 cores 32 bits solving it in less than an hour and it did not do it.

13 million nodes 37 minutes 10 seconds no solution by houdini and I believe that it also cannot solve it in depth 31 inspite of using the gaviota tablebases because the evaluation goes down too slowly.

houdini seems to be able to solve position number 2 but it needs more than 2 hours for it(considering Re6 for more than 5 million nodes is a good sign).

searching more than 40,000,000 knodes when the last 9,000,000 knodes is for the right move but still houdini does not choose Re6

cluster Rybka is clearly faster by a big margin(even if you use houdini on the fastest hardware that it can use and I guess houdini may need 1 hour instead of more than 2 hours on 8 cpu and 64 bits)

finally houdini solve position number 2
Here is the next line of the analysis.

It may be interesting to see result of rybka4 4 cpu for comparison:

Uri, do you think all 10 positions here are relevant for the engine strength? That sort of things happen in less than 1% of the games. Actually, "overtesting" on those things while developing an engine could harm her strength.

The problem I see with this postion is Re6 although a very good move, most likely the best, is not the only path to victory. White is winning after many different moves. But, black can defend for a long while, unless I am missing something. I will try to run Houdini on my machine and see what happens.
