I think you are dead-on with your analysis. You could have re-popped it on the flop, but the board being so dry, I think you were right to just flat and conceal your hand value (she could have read that flat as 2-overs with a BD flop option, floating one not wanting to give up so early. On the turn, you COULD have bet bigger, but – had the 4 not come on the river, you would have been happy to have that extra $30 in the pot…. I think it’s one of those spots where you are too good to throw it away – a smart player could be putting you on a total miss (AK-AQ-AJ) and just trying to take down the pot with A-7, A-2, or nothing at all. Sometimes you just can’t win. Reload and keep after it!
