Thanks.

I thought that movei is weak because it could not find it at tournament time
control and only at depth 12 failed high(I did not wait for it to solve the fail
high) but I see that crafty is even weaker.

Note that Movei can find a draw score after Ne5 but finding that white is
winning is hard.
