Probably most programmers would do better to strengthen positional play at the expense of tactics. But tactics is more fun! :-) And it will depend on what's in the evaluation and all the myriad other details of a particular program. Anyone who finds their program's playing strength goes up please donate a dollar per ELO to Steve's CCC fund! :-) >What about keeping WACBOOST variable, probably initialized by evaluation or some >eval related heuristics to determine some metric of tactical aspects for both >sides, like en-prised pieces, hanging pieces, pins, possible checks, forks, king >safety, weak as well as passed pawns, etc? It's something that could be tried. Certainly humans would be able to recognise certain positions as standing or falling on tactical swings alone, so perhaps a useful "high-WACBOOST" recogniser could be programmed.
