Game is 2/3NL, Bicycle Casino. Early in a session. Hero is early 60's serious rec with effective stack of $300. Villain is a youngish hispanic with his girlfriend sweating him on BTN with about $1500.
Hero opens UTG with KK for $15 (I know, could be larger, but I want to play a little more balanced and not have a preflop bet sizing tell). Folds around to BTN who calls. $29 pot after the drop.
Flop Th6s5c. Hero bets $20. Villan calls. Pot $69.
Turn 4d to complete the rainbow. Hero bets $40. Villain calls. Pot is $149.
Villain has the nut advantage. For the small preflop raise, villain can have all combos of 87, all sets. He could aslo be continuing with pair + SDs. Is this really a check/call instead of a lead?
As played, river was a 4c. Hero checks, villain shoves. Hero ends up folding. Villain shows a Td.
