You have to call this right?

[KingGeedorah]

fold, hes never bluffing and hes never doing it with worse

[JROK777]

A min raise on the river is never a bluff. Villian thinks that he has the best hand. You are behind...

[choccypie]

It's hard to put him on a hand if he's unknown to the table, but he's not going to be minraising with a second best hand on the river...so fold.

[xeanatic]

I always fold to these minraises with one pair.
Villian almost always does this for value.
Plus no draws missed that villian could be bluffin on.
so yeah I fold this even though we get sick odds

[Rednas]

Bet 3 on flop and 6 on turn.

[PleasureGuy69]

Probably has A9. No one really raises on the river at these stakes unless they have the goods.

[MortenTA]

This is a crap spot, but I think it's fairly safe to fold.
