quiescence & only generating appropriate moves

[flok]

Hi,

I hacked my move-generator to only generate catch/promote moves for quiescence search. At itself this works but this gives problems for the evaluation; now the mobility is all messed up and thus it generates silly scores and moves.
What am I missing here?

Mobility should not be affected by whether you plan to search only captures or not. You should calculate it as always.

You mean "capture", not "catch".

You are calculating mobility by generating all moves and counting them. Now it is messed up because you're not generating all moves anymore. The solution is to calculate / estimate mobility in a more efficient way.

HGM, RDM, thanks
