I read that in this position Fritz7 could find b4 only without futility pruning.

I have 3 questions:

1)Is 1.b4 the only best move for white?

I believe that humans do not understand much about chess and the fact that
humans said that b4 is the best move is not enough to convince me.

I will be more convinced if I find that Fritz can win a game against itself
after 1.b4 and cannot win a game against itself after a different move that it
prefers.



2)Can Fritz with the default setting(futility pruning) find 1.b4 after enough
time?

3)Does Fritz(without futility pruning) find b4 without changing it's mind(please
test for a long time)
