Only 19 hands on villain, in which he has played 100/47, so I think assuming not the highest caliber of player is fair. Other than that nothing particular to add to the hand.

BB: $31.21 (156.1 bb)

UTG: $20 (100 bb)

MP: $14.75 (73.8 bb)

CO: $32.15 (160.8 bb)

Hero (BTN): $24.90 (124.5 bb)



Preflop: Hero is BTN with 5 K K 4

UTG raises to $0.70, MP calls $0.70, CO folds, Hero calls $0.70, 2 folds



Flop: ($2.40) A 2 4 (3 players)

UTG checks, MP checks, Hero checks



Turn: ($2.40) K (3 players)

UTG checks, MP bets $0.60, Hero raises to $4.20, UTG folds, MP calls $3.60



River: ($10.80) J (2 players)

MP checks, Hero ??????

If yes, preferred sizing?
