After 30.e4, Black played the blunder 30...Qxb6?? After 30.e4, Chessmaster 9000 gives an eval of about 0.25 for White. Immediately after 30...Qxb6, the eval is 3.5 for White, and after a little over a minute (on a P3-733), the eval is 8.14 for White!! In the initial position, Chessmaster wants to play 30.Bf1 and then 31.e4: Time Depth Score Positions Moves 0:00 1/3 1.06 1564 1.Qc7+ Qxc7 2.bxc7 Ba6 3.e3 Ra2 0:00 1/3 1.09 2108 1.e3 Bd3 2.Qc7+ Qxc7 3.bxc7 0:00 1/4 1.15 4597 1.e3 Ra2 2.Qd8 Bd3 0:00 1/5 0.93 17130 1.e3 Ra8 2.Bf3 Bd3 3.Rd1 0:00 1/6 1.10 49687 1.e3 Ra8 2.Rc1 Bc4 3.Bf3 Ra2 0:01 1/7 0.95 140900 1.e3 Ra8 2.Bf1 Bxf1 3.Kxf1 Rc8 4.Kg1 0:03 1/8 1.01 287697 1.e3 Ra8 2.Bf1 Bxf1 3.Kxf1 Re8 4.Qc7+ Qxc7 5.bxc7 Ke7 6.Rb8 0:10 1/9 0.89 902821 1.e3 Ra6 2.Bf3 Rxb6 3.Qd8 c5 4.dxc5 Ra6 5.Bh5+ g6 0:30 1/9 0.97 2717347 1.Bf1 Ra6 2.Qc7+ Qxc7 3.bxc7 Ra8 4.Ra1 Rc8 5.Ra7 Ke7 6.e3 Bxf1 7.Kxf1 0:35 2/10 0.99 3180856 1.Bf1 Ra6 2.e4 dxe4 3.Qc7+ Qxc7 4.bxc7 Ra8 5.Bxb5 cxb5 6.Rxb5 Rc8 7.Rc5 Ke7 1:16 3/11 0.67 7093001 1.Bf1 Ra6 2.e4 Bxf1 3.exd5 cxd5 4.Kxf1 Ra2 5.Qc7+ Qxc7 6.bxc7 Rc2 7.Rb7 Ke8 5:48 4/12 0.89 32718884 1.Bf1 Ra6 2.e4 Bxf1 3.exd5 cxd5 4.Kxf1 h6 5.Qc7+ Qxc7 6.bxc7 Rc6 7.Rb7 Rc1+ 8.Ke2 Rc2+ 9.Kd3 So, e4 may be a good move, or even the best move. But it certainly doesn't win "in a few moves".... jm
