My engine is giving me headaches :) Its performing pretty badly against test positions (even thought it can beat me!). I have concerns over the following statistics: 1. The PVS search success ratio seems extremely high, of 180k attempts, only 9 fail (ie value > alpha && value < beta). 2. When writing to the hash table, of 50k writes 40k are lower bounds, 10k upper bounds, 20 exact. Does anyone else have any statistics for what I should be getting, or any suggestions where to look for errors???
