Takes 30 seconds for Skipper to find Bd3 in this position. That is too much when playing blitz games.

Wait. 4 seconds now. I had to disable SEE pruning in QSearch. Don't know yet if that harms/improves overall performance.

No disabling SEE in QSearch harms performance. It takes Skipper already at least twenty seconds to find a move at level 1 in position below:
