The position Martin Baumung posted (b2b3R/1np2pp1/Np6/n2K4/p7/N1k2p2/P1p3p1/2B2rqr w - - 0 1) gets resolved in my QSearch itself though ;-) so that gets solved at depth 1 ..... Lots more work yet to be done by me , esp on draw detection in eval and with search techniques ! It would be great if you can post the solution here - can I assume that the pv given by yace is the expected result ? (yet to exhaustively check that out ...) Thanks Mridul
