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.
