Actually I'm pretty happy with this result. This makes at least 5 of the 11 nolot positions that Zappa can solve in reasonable (a few hours) time. Of course, I am a long way from it playing the move over the board at tournament time control! 1. Nc3-e2 e6-e5 2. Nd4-f5 g7-g5 3. Bb3-f7 Bd7-e6 4. Bf7xe8 Qd8xe8 5. h2-h4 g5-g4 6. Nf5xh6 Bf8xh6 7. Rf1xf6 Bh6-g7 8. Rf6-f1 Qe8-a4 9. Ne2-c3 = (1.87) Depth: 17/38 00:58:56.78 2666999kN 1. e4-e5 d6xe5 2. Nc3-e4 Nf6-h5 3. Qg2-g6 Nh5-f4 4. Rf1xf4 e5xf4 5. Nd4-f3 Qd8-b6 6. Rg1-g5 Qb6-d8 7. Nf3-e5 Qd8-e7 8. Ne5-f7 Kh8-g8 9. Ne4-f6 Qe7xf6 10. Nf7xh6 Kg8-h8 11. Nh6-f7 Qf6xf7 12. Qg6xf7 = (2.28) Depth: 17/34 01:16:27.50 3451482kN Positions like these show that (IMO) more depth is *always* better. Maybe not a lot better, but Zappa is still finding new tactics at 17 ply. anthony
