PostPost subject: Null Move Help    Posted: Sun Feb 05, 2012 10:09 pm Reply to topic Reply with quote
I'm trying to implement null move pruning and I'm not sure how to test it. I want to determine if my simple implementation is actually working, or if it's pruning too much.

eg, null move off I get f4f5 d6f6 f2g1 (score is 56)

and with null move on the best moves are e4e5 d6d5 f2g1 (score is 48)

Is it normal to see entirely different lines with scores that are worse? Or should null move on return the same score and best moves more often than not?
