Not sure what you mean ? The Null move search is called with param (depth - 3)
so reducing the search depth for the null move.

Data structures are pretty much as TSCP, I think it is ok as it is because it
vastly speeds up my search and doesnt make any obviously buggy or totally stupid
moves with the null move code enabled. However if I play a number of games
against earlier versions of the program prior to Null move, they older code
quite easily wins !
