Pre-flop: ($1.5, 10 players) Hero is BTN :qh: :qd:
2 folds, MP1 calls $1, 3 folds, CO calls $1, Hero raises to $6, 2 folds, MP1 folds, CO calls $5

Flop: :4h: :8s: :kd: ($14.5, 2 players)
CO checks, Hero bets $12, CO raises to $28, $16 to Hero ($123.1)?

How does he play set hands? How does he play big upaired hole cards?

sets usually go call-raise/cr
he´s folding A-high on flop oop when 16-tabling. today he´s playing 7 tables, maybe he´s now focused enough to play me w/ air
