Another one, where White even gives a bishop to being exchange queens and transpose into a won pawn endgame (KPP-KPP only). It occured in a game Crafty 17.14 - Delfi 4.2, 40/10m P3/700 MHz. IIRC, only 4-piece tbs. were available. [D]8/8/2q1k3/1p2B3/3Q4/PKP5/1P6/8 w - - 0 86 86.Qd6+! I don't know if it's the fastest way to mate (I guess so), but also Qd6+ is human-like IMO, because after the very simple 86. Qd6+ Qxd6 87. Bxd6 Kxd6 88. a4 it's very easy for White. So no need to deal with "endless" counter-checks from a black queen... Analysis by Crafty 19.06, P3/700 MHz: 86.Kb4 Qb7 87.Qc5 Kf5 88.Qxb5 Qa8 89.Bd6+ Kg6 90.Qd3+ Kf6 91.Qd4+ Kf7 92.a4 +- (7.84) Depth: 1/7 00:00:00 +- (9.50) Depth: 10/25 00:00:10 3613kN, tb=9 86.Qd6+ Qxd6 87.Bxd6 Kxd6 88.Kb4 Kc6 89.a4 Kb6 90.b3 Kc6 91.a5 Kd6 92.Kxb5 Kd5 93.a6 +- (10.58) Depth: 10/25 00:00:11 3747kN, tb=13 +- (11.44) Depth: 13/32 00:00:22 8183kN, tb=223 Regards, Mike Scheidl
