[D]8/k7/3p4/p2P1p2/P2P1P2/8/8/K7 w - -

This position really bothers me ... and bothers nullmover...
nullmover takes a really long time to see that the pawn can be really won.

At ply 23 we see the keymove Kb1, but it needs 26 ply after 6 minutes we see
that Kb1 wins a true pawn.

The hashhit percentage is only 3%.
The FH is only 30%

Do I have to be worried ... or is this still all normal?
