What is the best move in this position?
Gromit likes dxe best for some time and then switches to Nh4, but the
difference is only small:
starting iteration 9. alpha=-50 beta=35
new highscore! Move Pd4xe5 Score=-38
Nodes: 2001449 nps: 14204.7
Finished iteration 9 after 140.9 sec. Best move: Pd4xe5 score = -38
Var.: 1.Pd4xe5 pg7-g5 2.Bf4-c1 pf6xe5 3.Ph2-h4 kg8-g7 4.Pg3-g4
bf5-g6 5.Ph4xg5 ph6xg5 6.Pe2-e3
starting iteration 10. alpha=-68 beta=17
fail-low-research of Pd4xe5(-168, -67): Score=-68
new highscore! Move Pd4xe5 Score=-80
fail-high-research of Nf3-h4(-80, -29): Score=-79 (564.22)
new highscore! Move Nf3-h4 Score=-70
Nodes: 17230003 nps: 14002
Finished iteration 10 after 1230.54 sec. Best move: Nf3-h4 score = -70
Var.: 1.Nf3-h4 pe5xf4 2.Nh4xf5 pg7-g6 3.Nf5-h4 pf4xg3 4.Ph2xg3
kg8-g7 5.Rf1-e1 re8-e6 6.Bg2xe4 re6xe4
I used a slow Sun, therefore I can't give more plys.
