I suppose this only happens when you use setboard and does not restart the engine? If so, check that you reset the killer list, history table the hash table plus any other tables that you might use in the search. This could change move ordering and give you different PV. >My question is if there is a simple way to check the global varaibles or global >arrays that have different values. There is, you can throw everything into a search namespace, or a tree struct, then it's quite easy to remember to resetting everything. >I can generate a copy for every global varaible and later compare the global >varaibles with their copies that are not used but this is not a general solution >because this means that I need to add more debugging code when I add more >varaibles. -S. >Uri
