1)is the sacrifice sound? if not, what is the refutation.
2)if so, do any engines find it on their own?

Thanks John. I shouldn't have caused confusion in the other thread by adding a second position.

Cheers,
Graham.

1) Yes, it is sound.

2) Unless the engine has very speculative evals, such as older Juniors, I doubt any would find it, even though the analytical tree is extremely linear.

Hi Albert,

I wonder on which basis you say that the sacrifice is sound? Do you have deep computer or GM analysis on that one?

Nevertheless I think your (informed) opinion is correct after the sac and acceptance (what's else?) here is SF 1.7.1 output:

[d]r1b3k1/pp1n3p/2pbpq2/3p4/2PPp1p1/PP2P1P1/1BQN1P1K/3RRB2 b - - 0 2

New game
