2) Fold ot villain's 3bet. He's likely not 3betting light, and all of the hands he would 3bet for value, you aren't in good shape against.

3) If you call preflop, you can only really call this flop bet, and fold to a turn bet. Raising the flop bet lets him fold all hands you beat, KK, JJ, KQ, etc, while you get the money in against hands that beat you (TT, QQ, AT, AQ, AA, AK, KJ, QT}.
