i recently added a TT which gave a very big increase in both speed and strength. the only thing i noticed (which definitely is a bug) is that i have to clear it before searching to be able to play endgames decently. in the middle game instead this behavior does not hurt too much, probably because of less hits?
the problem is that it seems it stores the wrong move and if it has time to do a real search it immediately changes it.
instead since i added null move pruning i notice that the engine, when in a winning position, makes a move it thinks is good but when it is its turn again it thinks he is in a bad position (??), this is really frustrating.
does any of this sound relatable or am in for a bug hunt?
thanks
search instability (maybe)
