In my chess program I tried out several "good ideas" that did not improve performance: 1) Mate distance pruning 2) Futility pruning in Quiescence search 3) LMR 4) Hash table ( This I have to try out again) Are there more good ideas that may not work ?

"Good ideas" that may not work

In my chess program I tried out several "good ideas" that did not improve performance:

1) Mate distance pruning
2) Futility pruning in Quiescence search
3) LMR
4) Hash table ( This I have to try out again)


Are there more good ideas that may not work ?

I like to have warnings in advance.

Re: Borislav Ivanov: a Lilov's add-on
