Note that the free version of movei(Movei0_799) that you mentioned at previous
post has no king safety evaluation.
latest version changes its mind from 8...Nxe4 to 8...Qd3
but later does not like Fritz's move 9...Bd7 and prefers 9...Qxe4
+2.70/10,+2.67/11

10...Qxe4 +1.92/10,+2.05/11 seems also better from movei's point of view.
The scores at move 11 starts to drop
11...Qxd7 +1.77/9,+1.41/10,+0.96/11

I think that winning may be also a question of luck and you may fail to win if
you give the program 5 seconds for a move and win when you give the program mote
time because by some bad luck it is going to play a worse move at slower time
control.
