Flop: ($3.15) 5 9 5 (4 Players)
UTG checks, UTG+2 checks, CO bets $0.50, Hero ???

Here's the story so far...
900 hands at table - TAG and catching/showing a lot of premium hands

UTG+2 is reckless to say the least.. 65% VPIP 20% PFR
He's playing the limp/call/call game and the table has followed suit.

Flop - I reason I'm against Ax/9x/22-44/66-88 and winning the showdown.
Nothing about this says AA/99 to me, and 54s/65s/55 are remote possibilities.

I pause for a few seconds and shove all $9 here,
basically because I don't want to bet $3,
then have $6 on the turn and possibly an extra hand or two priced in and getting lucky.
I've also seen quite a few TP/MPP glory calls in similar overbetted multiway pots.

Is a $3 bet the best play here?
