Re: sudden river aggression
 

I agree with the majority of the posters here.

I think this is an easy raise.

I'm guessing it's a JT that suddenly thinks he has the best hand. If only he knew... [img]/images/graemlins/smile.gif[/img]
Even against an unknown I'm giving enough credit for just calling the 3-bet if he does indeed 3-bet.

Re: sudden river aggression
 

Without reads I would raise. Checking the turn just does not make any sense with a set. On the other hand, if this was a tricky player with very creative moves, I might consider just calling. Yesterday I met someone like that. He was checking all the way with the nuts and then check-raised the river. But these are so rare cases that you should not miss the value by not raising without a specific read.
