V1 $1000, V2 $1500, V3 $500, I cover.

My image is bad because my last straddle attempt failed miserably. But I'm not one to give up. I straddle and find Q♥ 9♥

V1 at CO makes it $35, V2 button calls, V3 BB calls.

V1 is a grinderish dude picking on my straddle. V2 and V3 are fish, very stationy preflop and to a lesser extent postflop. I 3b to $100. V1 goes away, V2 and V3 call.

Flop: Q♣ 7♠ 3♥ Pot $337 BB checks...

1. Was 3b bad and why?
2. What do we do now and what's our plan for the hand?
