No problem

I have in the code that I posted:
"if (nullconditions(depth))"


In case that you do not want to use null move you may have

int nullconditions(depth)
{
  return 0;
}


Even if null move at every node does not work in some games it does not mean
that it cannot work with the right nullconditions functions that often return 0
but not always.

I want structure that will help programmers to try different ideas in every
game.
