Looks standard to me, UTG looks like a fish because of the limp and stack size. Don't really think too much of SB's call for the same reasons (not full stacked and looks like a fishy call from the SB). Oh, and we block AA/KK.

I play this hand the same way.

SB is likely overplaying 99-JJ. UTG does indeed look like a fish based on the stack size, but this limp -> all-in from UTG is a bit like ABC poker with aces and that's pretty much a standard fish move with rockets or kings. After all, in NL10 people have very unbalanced 3-betting ranges and like no balance in four betting ranges, you get 1:1.5 (with the assumption of sb folding), so a real equity of somthing along 1:1.5 vs 1:2. With no read on the player, given the limit I tend to fold ...

I think the line is fine due to UTG looking bad. Once MP folds we shouldn't be worried at all for 80bb stacks with the extra money SB has put in to juice the pot.

There's also only half of the KK+ combos possible due to the blocker effect.
