[toss]

I disagree about not auto-checkfolding the river UI if Button calls the turn after you.

I'd probably also raise if I were going to continue with this hand. You say UTG+1 is pretty laggy so I'd want to raise and knock out some better hands that Button may hold. If Button and UTG both call your raise you may get an oppurtunity to showdown cheaply if UTG checks the river.

Edit: I feel folding the turn is best.
