No reads, stacks $100. Only real read is he hasn't been floating me a ton or anything.

1. Mp limps, folds to me in the bb I raise to $5.25 with [Js], mp calls,
2. Flop [Th][3c], pot $11. I lead $9 and he calls.
3. Turn , pot $29. What do I do here?

If you bet $22 or so, are you calling a shove for $70 more?

I probably check, hoping MP checks behind like most villains seem to when they hit a flush.

Ship heart river please dealer, else I may actually check/call river.

Say I check/call a $12 turn bet.

River comes . You guys fold to a $20 bet with about $55 already in the pot? (getting almost 4:1)

If the guy is aggressive at all (youve been in spots like this before and you checked the turn and he bet it), I would seriously consider a CRAI.
