gorgeous LTC computer game + test positions

just saw this on playchess -- ZM II blows the HIARCS beta out of the water by giving it a heavy dose of its own medicine -- an early, uncompromising, overwhelming KS attack.

game is essentially over by move 20. pretty amazing given the difference in age & the fact that HIARCS was probably running on at least equivalent h/w.

some positions people may wish to test/compare their personal or favorite engines on--

g6!! HIARCS is unable to find the best refutation, though brief analysis with rybka seemed to suggest this is best move at any rate.

[d]r4r2/3bb2k/p2Nppp1/2q5/2p4P/P4N2/1PP1QP2/2KR2R1 w - - 0 24

h5!

and 2 moves later, both machines reach evaluations of +3 for white.

This is called Rook pawn Tin opener.

you will find number of similar examples in STS 8.0.

interesting -- R3 human hasn't found it in 45 minutes of octal analysis (granted, Nf5 also wins). meanwhile on my quad it popped up in IDeA in a couple minutes & was the preferred move a couple mins later. really diggin the new aquarium.

g6 not possible. You must mean hxg6?

yanquis1972 · Post by **yanquis1972** » Thu Mar 04, 2010 3:46 am

sorry, mistake - the diagram is post-move. the white pawn should be on g5 for tests.

M ANSARI · Post by **M ANSARI** » Thu Mar 04, 2010 6:05 pm

I think the critical position was here (although black is still struggling)

[d]r1q2rk1/3bb1p1/p2ppBp1/8/2p1N2P/P4N2/1PP1QP2/2KR3R b - - 0 21

Here Hiarcs took with the pawn which seems the wrong plan as it makes a future h5 extremely dangerous. Rybka 3 prefers to take with bishop and give up a center pawn for what seems to give much better chances for a draw.

yanquis1972 · Post by **yanquis1972** » Thu Mar 04, 2010 9:08 pm

interesting, didn't even both to check if there were saving chances after move 20. from my brief analysis msot critical was HIARCS response to g6. (rybka seemed to think fxe was much better, but again, this was just a couple minutes of IA)

i may do an IDeA study, it is difficult to believe for a human, at least for me, that black is not simply lost after g6.
