$0.05/$0.10
SB: $17.49 (174.9 bb)
BB: $14.49 (144.9 bb)
UTG: $2.86 (28.6 bb)
MP: $19.01 (190.1 bb)
Hero (CO): $10.15 (101.5 bb)
BTN: $17.40 (174 bb)

Preflop: Hero is CO with Ad 3d
UTG folds, MP raises to $0.30, Hero raises to $0.90, 3 folds, MP calls $0.60

MP 19/19 119 hands

Maybe the 3b is too light CO vs MP?

Flop: ($1.95) 7c 7d 6d (2 players)
MP checks, Hero bets $1.10, MP calls $1.10

Turn: ($4.15) Jc (2 players)
MP checks, Hero bets $2.70, MP calls $2.70

River: ($9.55) 2s (2 players)
MP checks, Hero bets $5.45 and is all-in, MP calls $5.45

Is this a good spot to 3 barrel bluff?
