Nimzo amazingly hasn't smelt it yet here. e3 is leading to the endgame from which i think DB misevaluated it bigtime. So does nimzo of course, but not so weird is that a preprocessor misses after f3 that Bh5 wins bigtime, hmm perhaps it is dissappointing, because IMHO it's a simple tactical win! What might matter is that you perhaps had turned on 'futility' forward pruning last 2 plies? Perhaps checkout next time the tactical line it outputs first before saying TADA :) >Who says SE is a bad thing? :) I'm pretty sure that DIEP has more SE than nimzo ever will, but the 'piece threat' extensions are picking up for nimzo huge amount of tactics usual! Anyway, it's not about 'who has more extensions' here. it's about the fact that f3 is a major blunder! >Slate
