1. Pre-flop is standard.

2. Flop three-bet is absolutely necessary, particularly if it will force out some of the one-bet types. Waiting until the turn makes some sense here, but you can confront a few with 2 cold here and I don't really want to miss that opportunity. (I do encourage someone to pen a reply about why waiting until the turn is right here... I think it's damn close.)

3. Given flop turn is standard.

4. On the river I don't like a fold here. My one comment is that you should be prepared, against tight-weak players in SB's position, to be raising this river a reasonable amount of the time if you think there is any legitimate chance you have MP2 beat but not SB. This is a classic promotion raise set-up, and it can be extremely profitable to identify it here.

I don't think it applies on this river because I don't think SB has a straight/two pair, or else we would have heard about it, and a flush isn't folding.
