I definitely agree with nutsinho and mcat. I'd be sure to 'think' before calling, at least on the turn and try to represent AJ/AQ so he will continue to barrel AK.

Question for mike: many times the J, Q, K or heart comes in on the turn and these usually kill our action. If our opponent bets again are we shipping it in to protect our hand from the 4 flush? I think this is more important for the heart coming in and not the JQK scenario.

Lately I've been stacking off when the draw gets there with mixed results and wondering that, after calling the flop, we should avoid getting it AI when they bet strong again on a turn heart. This is of course very weak thinking and so I just get it in anyway.
