Zappa used to need 20 ply for this one, now it gets it in 4 :)

1... Bd4-b2 2. Ke7-d7 Kf4-e3 3. Kd7-c7
 = (1.79)	Depth: 4/9	00:00:00.02	4kN
1 ...Bd4-b2++
 + (2.17)	Depth: 15/33	00:00:04.92	4997kN
1... Bd4-b2 2. Ke7-d7 Ra6-a4 3. Kd7-d6 Ra4xe4 4. Bd5-f7 Re4-d4 5. Kd6-c5 e5-e4
6. Bf7-h5 Rd4-d2 7. Kc5-b4 e4-e3 8. Kb4-b3 Rd2-g2 9. Bh5-f7
 = (2.64)	Depth: 15/33	00:00:08.59	9102kN

Now I just need to do some test games to make sure my passed pawn eval is
better, and not just more aggressive ;)
