Hero folds.

The turn bet of 1K is strange because its unlikely for hero to fold. I think in general you are either behind a little or a lot. I think its unlikely that villain has a drawing hand and is setting up a bluff on the river given that hero has the A [img]/images/graemlins/diamond.gif[/img] and villain has not made an attempt to drive hero out of the pot.

Given the original 50 hands I estimated (88,99,89,ak,aq,aj,a8,a9, aa) there are only 37 hands left after taking into account the turn/river (including hero's holdings).
I can see villain betting the entire range.
Hero only splits the pot with aq,aj (12 hands or ~1/3).
So hero needs 6:1 in the pot to call;
I'd call up to T1200 or so.
