I think that tactical advantage is result of pattern recognition that is positional understanding. I can show example from humans. intelligent beginners without positional understanding may not be afraid from the idea Nf7+ Kg8 Nh6+ Kh8 Qg8+ Rxg8 Nf7# so they may miss it in blitz but not at long time control when they think about it. strong players are not going to fall for that trick even in blitz because of the fact that they have better pattern recognition or better positional understanding. If Rybka knows about a lot of patterns and detect it by evaluation then of course it has better evaluation that help it to be better in tactics. Uri
