It breaks principals, but remember that classical values give a tempo as about 1/3rd of a pawn. So just because your opponent is wasting a tempo (by playing a sub-optimal opening move) don't expect yourself to be able to win. You'll only set yourself up for disappointment. Inaccurate opening moves from your opponent only promise you a comfortable middle game (if you play accurately) not a win. Especially if they're white. White can waste a few tempi and be fine because white moves first.
Anyway:
I REALLY REALLY struggle when playing black, specifically when people play the Parham/Nakamurra attack/opening. You know the one. The one that means I suck at chess. White starts with 1.e4 and no matter what you do its followed by 2.Qf3. Maybe even a little 3.Bc4 if he's feeling frisky. Then, the most frustrating thing ever happens: they dance around with their queen and end up destroying you some how. I would, just once, love to be able to punish someone for moving their queen so early in the game. It goes against everything we're told to do when following opening principles. Maybe there's something to it though, as I cannot stop it, and Nakamurra has used it. Anyone who can help by answering this without sarcasm or arrogance, and wants to help a guy out, that would be fantastic, and I'd be forever grateful. Thanks in advance.
