Final Pot: 23 BB

It felt like I needed to raise but I couldnt figure out where. Any ideas?

I'd raise the turn. At first I thought the river cap was too much, but given UTG's obvious crappiness, I think it's good.

[trentcroad]

I might raise the flop here and Id prob cap the river as you did given the read and SB's likely holding.

[JrJordan]

I'd probably just call the flop and turn like you did. Most people in the SB aren't firing to barrels with just overcards. When you hit the river though I like the cap. UTG's 3-bet looks like spewing to me instead of a real hand, since he would've raised earlier and the 9 only completes one straight combo (78). Plus, you have an overlay of SB calling with his overpair.

I would raise the turn. I think the river plays differently if you do so unless villain has a set.
