test position -- giri-grandelius

bm e5!!

Qc3 may also be good enough for an edge, but i believe e5 is better.

[Date "2010.05.27"]
[White "Giri"]
[Black "Grandelius"]
[Result "1-0"]
[WhiteElo "2642"]
[BlackElo "2476"]

28. Nd4 Bd7 29. Nxe6 Bxe6 30. Qg5 Rf8 31. Rxe6+ fxe6 32. Qg6+ Qf7 33. Bxc6# 1-0


it is amazing how long it takes computers to sift through the tactics of these positions -- junior seemed to be the only engine i tried that gave a 'human-like' eval throughout the game (and intuitively finds e5 as well)

Yes, He's really very brilliant. :)

I found some of his annotation of GM games really entertaining.

Stockfish-1.7.1 (8 threads) switches from Qc3 to e5, but only after a long time:

Post by yanquis1972 »

the above postings -- particularly the second -- were very likely lucky searches -- if you'd like run rybka 4 on one core & see how long it takes to switch to e5. i'm running the position on a quad & 12 core & its yet to switch at d22 on either machine. the 12 core appears to be about to switch at d22 approaching 30 mins of thinking at 700+ kn/s.
