Put in one more raise?

[blumpkin22]

First hand at table. I was folding the turn UI, but wanted to see where I was with a flop bet. The river bet threw me off; is he trying to donk-3-bet it? Put in one more raise and call a 3-bet?

I would grit my teeth and raise. I'm pretty sure SB has the 4th ten here, but it doesn't have to be a very good ten. (T [img]/images/graemlins/diamond.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img] would play this way.) Without any reads to suggest the SB would chuck a crappy ten preflop to the raise, I don't think we can automatically put him on QT, AT or a boat yet. Raise and call the three-bet.
