Ok, pawn g7 goes to g6: >[D]q1k1r2r/1p1b2pp/p1n1p2n/2B1PpN1/3p1P2/P2B3P/P1P3P1/1R2QR1K w - - This seems to be a good attempt to "repair" the test position. >I this position most engines will play Rb6 soon, I guess. I didn't analyse Rb6 in the new position. Ruffian prefers 1.c3 up to ply 14, obviously to open the c-file. Maybe Black's move of the bishop to c6 provides some counter chances (against g2, if the Pb6 moves eventually), but Ruffian's evaluation shows big white adavantage too: Analysis by Ruffian 1.0.1 (P3/700, 64 MB hash): 1.Bd6 Ne7 +- (1.87) Depth: 1/1 00:00:00 +- (1.84) Depth: 2/4 00:00:00 1.Qf2 Rd8 2.Bxd4 Nxd4 3.Qxd4 +- (1.89) Depth: 2/5 00:00:00 1.c3 Nd8 2.cxd4 Bc6 3.Bd6 Nhf7 4.d5 Bxd5 5.Rc1+ Bc6 6.Qa5 Nxd6 7.exd6 Qb8 8.Qe5 Qa7 9.Qxg7 +- (2.16) Depth: 2/5 00:00:00 +- (3.48) Depth: 14/34 00:04:12 108336kN Regards, M.Scheidl
