Cap preflop, raise flop. We're either behind drawing to 2 outs, he's behind drawing to 6 outs or 3 outs with AK or a big A, or he's drawing at 2 outs with a weaker pair. (I assume he doesn't have a 6). If he re-raises on flop, we slow down, otherwise we pummel him. BTW, if we cap preflop, he probably checks to us on flop unless he's got aces or kings, unless he's tricky, and then we are in control...
