River play on a four flush board

[Peter]

5/10 6 max on Party.

Button openlimps. Button is loose and somewhat passive preflop. SB folds and I check in BB with A [img]/images/graemlins/diamond.gif[/img]2 [img]/images/graemlins/diamond.gif[/img]. I had been raising button a couple of times already when he openlimped. This time I decided to check.

Flop: A [img]/images/graemlins/heart.gif[/img]K [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/spade.gif[/img]
I bet, button calls.

Turn: 4 [img]/images/graemlins/heart.gif[/img]
I bet, button calls.

River: 6 [img]/images/graemlins/heart.gif[/img]
I check.

It seemed to me that button didn't have an ace, because he probably would have raised the flop. He would call with any heart, and would fold if he didn't have one. He might bet hands without a heart though.
What do you think?

Thanks,
Peter
