Full Tilt - $0.50 NL (6 max) - Holdem - 5 players

Villain  28/18 AF:1, 4 bet = 0, fold to 3B = 67% Raise flop and turn 15%. I saw him ones raising 3 x flop TPTK.

BB: $50.00

UTG: $61.95

Hero (CO): $50.00

BTN: $31.50

SB: $63.20

SB posts SB $0.25, BB posts BB $0.50

Pre Flop: ($0.75) Hero has Ks Kc

UTG raises to $1.50, Hero raises to $5.25, fold, fold, fold, UTG calls $3.75

Flop: ($11.25, 2 players)

UTG checks, Hero bets $9.00, UTG calls $9.00

Turn: ($29.25, 2 players)

UTG checks, Hero bets $14.25, UTG calls $14.25

River: ($57.75, 2 players)

UTG checks, Hero bets $21.50 and is all-in, UTG calls $21.50

I put him a lot on pairs like 88, 99, TT, perhaps JJ. I decided to bet big flop to charge these hands. Turn I bet smaller to let him shove over me, but felt perhaps 12 would have been better bet size?
