Definitely need some help with this one. Not sure whether my calculations are accurate, so please correct me if I'm wrong...

UTG opens, SB calls, we call in the BB w/TT. Flop is 843

Flop gets checked around.

If we assign UTG this range pre:




*I don't think he'd check back value hands on this flop. I don't see any 2P hands here on the flop. Sets, overpairs, and 8x likely would've bet flop to get value because a 3rd club on the turn might kill action. FD's, especially w/Ax, "likely" would've bet here. However, FD's can also go into his check back range.

*Hands that check back: Overcards, smaller pairs 55, 66, 77. Perhaps FD's could go here if he plays them passively.

Turn brings A. SB checks, we check, and UTG bets .25c.




And we assign him this range on the turn after he bets ("likely" for value) and after making the above inferences:




So it's .25c/.93c = ~27% equity

Hero should call in this spot because we have enough equity here? If we call, we're hoping to find a free SD?
