Hero posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 1.5 BB) Hero has Q♦ J♥

fold, fold, fold, fold, Hero raises to 3 BB, BB raises to 7 BB, Hero raises to 21 BB, BB calls 14 BB

Flop: (42 BB, 2 players) 5♦ K♥ 3♥
Hero bets 21 BB, BB calls 21 BB

Turn: (84 BB, 2 players) 3♠
Hero checks, BB bets 44 BB, fold

i 4bet as a bluf and give up if he didnt fold
but the flop was very good for a cbet

i try to 4bet bluff (with blockers) villains that have a high 3bet in position
in BTM vs co and btm vs MP and BB vs sb

small example :

BTN: 170 BB (VPIP: 22.06, PFR: 17.65, 3Bet Preflop: 7.41, Hands: 71)
SB: 94.7 BB (VPIP: 20.00, PFR: 10.00, 3Bet Preflop: 0.00, Hands: 20)
BB: 92.9 BB (VPIP: 30.77, PFR: 7.69, 3Bet Preflop: 0.00, Hands: 13)
UTG: 169.7 BB (VPIP: 16.45, PFR: 12.55, 3Bet Preflop: 4.11, Hands: 236)
MP: 38.5 BB (VPIP: 36.84, PFR: 5.26, 3Bet Preflop: 0.00, Hands: 19)
Hero (CO): 100 BB

SB posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 1.5 BB) Hero has 7♠ A♦

fold, fold, Hero raises to 3 BB, BTN raises to 9 BB, fold, fold, Hero raises to 24 BB, fold
