BB: $11.26 (225.2 bb)
UTG+2: $5.07 (101.4 bb)
MP1: $4.93 (98.6 bb)
MP2: $6.86 (137.2 bb)
MP3: $4.56 (91.2 bb)
CO: $5.32 (106.4 bb)
Hero (BTN): $6.44 (128.8 bb)
SB: $6.36 (127.2 bb)

Preflop: Hero is BTN with Q K
4 folds, CO raises to $0.15, Hero calls $0.15, SB calls $0.13, BB calls $0.10

Flop: ($0.60) K 5 T (4 players)
SB checks, BB checks, CO checks, Hero bets $0.50, 2 folds, CO raises to $1.35, Hero ????

CO is 20/16 over 50 hands.
SB is 61/4 over 28 hands.
BB is 15/10 over 48 hands.

Firstly - are you ok with the call preflop or would you rather 3 bet? CO sample is small but they do seem positionally aware.
Secondly - how do we react to the flop X/R?
Third - if we call, what's the plan on the Turn/River?

Thanks
