In this position: [D]2kr3r/1q1bbp2/3pp2p/Q7/3N1P1p/2N4R/PPP3Pn/2KR4 b - - 0 21 Chessmaster 9000 gives 21...Rdg8 an eval of 0.27 for White. After 21...d5, the eval is 1.27 for White, exactly one point higher. And then, after forcing the moves 22.Na4 Bxa4 23.Rc3+ Kb8 24.Qxa4 Rd6 25.Rb3 Rb6 26.Rxb6 Qxb6 27.Rd3, the eval is over 2.5 for White. There must have been a better line for Black.... Is 21...Rdg8 that much better of a move? jm
