AQd on monotone flop: Could be for value, could be FE

[BarryLyndon]

Blinds 100/200

Hero (3,500), UTG+1
Villain (2,800), MP1

There is a 50/50 chance Villain will bet if I check - he may trying to float me, as I've been the most aggressive at table and him the most responsive. But he's not a great flop player, so I don't really know if he thinks this way, and he is in MP after all. Anyway:

Folds to Hero from UTG+1 with A [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/diamond.gif[/img] to 550, Villain calls in MP2, folds

Flop: 3 [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/diamond.gif[/img] (pot 1400)

Hero bets 1400.

The pot was big and I wanted to committ myself + get some FE against pocket pairs, which I'm sure there are a few in his range. Take it down or get it in felt standard.

However, I was confused about my best line because:

1. There is value I'm getting from a fold
2. There is value I'm getting from a call (Kdx, Adx).
3. There value I'm getting from a CR here.

Which is my best line?
