River is super obvious. I don't think he can bluff there knowing that BB will have tonn of combos that have Td or Kd.
Turn sizing is atrocious, it's a 4 flush 4 straight board. If he bets that big it means he should have quite a few bluffs, and I can't think of that amount of bluffs compared to flush and Tx combos he can bet there. Meanwhile he wants to bet Tx and flushes and sometimes sets for thin value. Sizing should be small if he decides to bet.
EDIT: given that it's liveament level of poker I am guessing CO had Kd and BB got stubborn with Td.
Think turn sizing should be closer to .5psb and river should generally be villain dependent. Can check non Kd value vs some who won't call down ever and adjust sizing vs others who will.
