All the moves except the last move
I see that Qa7 is not single and there is also Kc6.
This+some pruning may explain the fact that movei needs more time then I

Maybe I will fix it so next movei will be able to solve it more easily.
I see that by changing some pruning parameters I can get it at depth 8.
