Hi,
MP1 is vpip 18 y 5 pfr.
My flop bet is a bit low because I wanted him to call or raise with AK,QQ, etc...

Full Tilt Pot-Limit Hold'em, $0.25 BB (8 handed)

saw flop

MP2 ($20.65)
CO ($25)
Button ($16.18)
Hero (SB) ($27.88)
BB ($7.77)
UTG ($10.69)
UTG+1 ($25.97)
MP1 ($22.82)

Preflop: Hero is SB with
1 fold, UTG+1 calls $0.25, MP1 bets $1.10, 3 folds, Hero raises to $3.50, 2 folds, MP1 calls $2.40

Flop: ($7.50) (2 players)
Hero bets $3.50, MP1 raises to $18, Hero ?
