Sadly many will figure this out once that damn book comes out but....

basically the pot is too small and you are to deep compared to the pot to semi bluff raise this ON THE TURN. flop woulda been a diff story.

Now as far as his bets...... It looks like he is betting A-a really strong hand that he wants you to raise or B- a worse heart draw. Either way you gain nothing from raising ether of those hands. If he has the jack then it depends what you read is on him (making a call the best play most of the time given the average players proclities)

Theres a bit more to it than that but i suck at writing and will stop now.
