Playing 0.50/1 cash at Gala Nottingham (sigh). Me and the villain concerned are both playing roughly £300. He is a semi-solid live player (Shaddy from DTD if anyone knows him). He knows me to be loose aggressive but respects my game. He might think I was slightly tilted cos I had just lost a reasonable pot.
two limps to my button, I limp

, SB completes (playing £24), Shaddy checks.

Checks to me. I bet £4, SB calls, shaddy makes it £16. Folds round. I raise to £35. SB calls all in (defo on heart draw imo). Shaddy tanks for a short time then calls. He definitely has a 3 in this spot but could be any 3 ofc from the BB. May or may not reraise 43 in this spot, not sure.
5minutes later the dealer has sorted out the side pot...and we get a turn card

he checks, I bet £55 (though the side pot is only £24). He tanks for a bit longer a calls. I'm pretty sure he'd raise K3 or 43 at this point but not 100%.
River

. He tanks and bets £75. He has about 120 behind.
What's the move here?
