Go for overcall or raise on river in LP w/ nut straight?

[weevil]

Both opponents are reasonably aggro (~1.50) and very loose PF. The CO behind me happened to have most of his agg on the river though, (7 I think).

Final Pot: 10.66 BB

This had me a little confused at the time. I was probably guaranteed a bet from BB, and the offchance that he would 3bet and I could make sure the river got capped, but given CO's agg, should I have gone ahead and 3bet hoping for a cap from him whether the BB came along or not? I tend to think it didn't much matter either way. Yes, no?

I think you have to 3bet here. You only get (usually) 1 more bet if you just call but you're likely to see a call and a cap leading to at least 1 but usuually more bets going in.

Edit: it matters

This pot is pretty small. I wouldn't be shocked if BB doesn't call when it's two more back to him, if he doesn't have a T.

I think it's a clear raise when you have a solid read that you aren't splitting. When you might be, it's close.
