Tom,

I read another thread about Killers and have an opinion on it.

- Doing captures separately speeds you up considerably
- Doing an on the fly legality check for killers speeds you up noticably
- Doing SEE based pruning of losing captures in the qsearch cuts the number of
nodes and improves node/qnode ratio. You don't have to SEE sort for it. I doubt
SEE sorting is a winner anyway.
- Having the former, you can skip losing captures in the normal search as well
with it, and do those later. Improves sorting noticably.

This goes for all versions and half baken versions I have ever made.

Bas.
