TheaN: Good analysis and theme listing <notyetagm> (as always), but I think that in this example, White does not win purely from 15.Nc6. Might be White's best move as it pretty much forces a kingside castle which is surely in Black's disadvantage, but decisive after 15.Nc6 I believe not. Actually, Fritz's verdict is that Nc6 and Qe2 are alike on move 15, leading to the same tactic in a different move order. And they are both only ~0.3 better than the simple h3: do take note that this move, and most others below, DO use the Nc6 tactic, which is then probably the only move to make real progress, but it's NOT decisive.
