LJ is 33/0 over 6 hands. BU is 34/28 over 128 hands, bith a 40% fold to 3bet.

Preflop: Vs. a Lojack RFI i'm calling A4s and vs a BU RFI I'm calling or raising. Vs. and open and then a call, I'm certainly getting fine odds to call. Looking at this now, maybe this would have been a good hand to squeeze? The only thing that makes me think it wouldn't be is BU's loose stats and his low fold to 3bet.

Flop: LJ bets, keeping his range uncapped. BU then raises. I figure it's close, but that I have enough equity here with the nut flush draw, and some pretty good implied odds if a diamond overcard comes.
LJ then goes all in, and BU calls. This is where I'm confused. They are both obviously representing strong hands, but I'm pretty sure the math shows I still have enough equity to call here.

What do you guys think? Squeeze pre? Call the all in? Thanks!
