CM9000 on an old Athlon 700 MHz with 64 MB of hashtables using my Junior
personality shows this analysis:

Time	Depth	Score	Positions	Moves
2:06	9/15	0.18	16286220	1.a7 e4 2.dxe4 Bxe4+ 3.Bd3 Bc6
					4.Bg6 Ka5 5.Bf7 Kb6 6.Bxe6 Kxa7
					7.Kd3 Bb5+ 8.Ke4 Kb6 9.b3 Bc6+
					10.Bd5
3:59	10/16	0.15	31654409	1.a7 e4 2.dxe4 Bxe4+ 3.Bd3 Bc6
					4.Bg6 Ka5 5.Bf7 e5 6.Kd3 Kb6 7.Kc4
					Bb5+ 8.Kd5 Kxa7 9.Kxc5 Be2 10.Be6
5:26	10/16	0.41	44081605	1.Bg2 Bxg2 2.e4 f5 3.gxf5 exf5
					4.a7 fxe4 5.d4 e3 6.dxe5 Be4+ 7.Kd1
					Kc4 8.Ke2 Kd4 9.e6 g5 10.e7 Bd3+
					11.Ke1
6:31	11/17	2.23	52856011	1.Bg2 Bxg2 2.e4 f5 3.gxf5 exf5
					4.a7 fxe4 5.d4 e3 6.dxe5 Be4+ 7.Kd1
					Bc6 8.e6 Kb3 9.e7 Kxb2 10.e8=Q
					Bxe8 11.a8=Q Bh5+ 12.Ke1

Thus after 5:26 it prefers Bg2, but needs 6:31 to really give it a winning
score.
