nolot number 3 again

Post by Uri Blass » Sat Dec 18, 2010 4:33 pm

[D]r2qk2r/ppp1b1pp/2n1p3/3pP1n1/3P2b1/2PB1NN1/PP4PP/R1BQK2R w KQkq - bm Nxg5

Is the solution correct?

After Nxg5 Bxd1 Nxe6
Houdini with slow hardware has a fail low for black at depth 23.
Maybe someone with better hardware and more time can use houdini to find if white is really winning and if yes if houdini can find Nxg5 after many hours of search or maybe Nxg5 is not the only winning move.


New game
[D]r2qk2r/ppp1b1pp/2n1N3/3pP3/3P4/2PB2N1/PP4PP/R1BbK2R b KQkq - 0 1

AMD Phenomx4 9850 2.5ghz 528 MB Hash. Will keep updating the analysis. Note that GUI is arena so minus score is bad for black good for white.

After Nxg5 Bxd1 Nxe6
Houdini with slow hardware has a fail low for black at depth 23.
Maybe someone with better hardware and more time can use houdini to find if white is really winning and if yes if houdini can find Nxg5 after many hours of search or maybe Nxg5 is not the only winning move.

I put both Qb8 and Qc8 for over an hour (2x 3.6GHz) and got a +1.xx eval for both. I forgot to save the analysis of Qb8 (sorry), but here is the analysis after Qc8:

Is the solution correct?
Crafty finds Nxg5 in about two hours, and sticks with it (though the search is still running):

Houdini with better hardware surprised me by finding Ng5 from the root position(4 cpu 32 bits)
