Could I have got it all?

[JonLines]

William Hill, Pot-Limit Hold'em, £0.5-£1 (6 handed), £100 Max buy-in

Button (£70)
Hero (£95)

Button just loves to raise when checked to... its like a fix he needs.

Preflop: Hero is BB with A [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/club.gif[/img]

Checked round to Button, he bets pot (£3.50), SB folds, BB calls.

Flop: (£7.50) K [img]/images/graemlins/diamond.gif[/img] A [img]/images/graemlins/club.gif[/img] 8 [img]/images/graemlins/spade.gif[/img]
Hero Checks, button bets pot (£7.50), Hero calls

Turn: (£22.50) 2 [img]/images/graemlins/heart.gif[/img]
Hero checks, Button (after a very long wait) bets pot (£22.50), Hero re-raises all-in, Butoon folds.

Final Pot: £67.50

Just wondering if a flat call then a raise on the river might of worked, or a smaller raise? Or was it better to take the pot now? Cant see any draws im afraid of.

Any thoughts would be appreciated.
