Final Pot: t1220

Convertor is missing turn betting (so turn and river pot totals are also wrong - is there a problem with the convertor?), turn betting is as follows:
Hero bets [800].
Button raises [1600].
Hero is all-In [1640]
Button is all-In [700]

Is it obvious what Button has?
Hint: this is not a bad beat [img]/images/graemlins/wink.gif[/img]
