Very good Louis! It shows it is possible and it sets a nice benchmark, for improving Stockfish. So far it maybe goes wrong in pruning somewhere, sometimes I see Bxh6 appear with a few correct moves and really big scores, but then apparently a partial refutation is found and the move disappears quickly again so it does not get much benefit from having been the PV.zullil wrote:It takes quite some time, but Stockfish-1.7.1 (8 threads) succeeds:

I made some progress I think, nothing spectacular but I introduced a new Stand Pat Futility Pruning, I did not think I could get that to work at all because there is not really such a thing in Glaurung or Stockfish, a hybrid of Razoring, Futility Pruning and the Stand Pat Return static eval > beta of the quiescence search. At least that is what I had in mind and I think I like it enough to keep it in for now, unless I discover that it isn't supposed to work
I trust it enough now to publish the code, but it was only conceived one and a half hour ago so beware...
