Loose table with 6 players
.25/.50 blinds NLHE $50 behind
My hand: 2c 5d
I 3x raise to 1.50 Under the gun, two callers, BB also calls
Flop 3d Td 4c
Big Blind leads out $6 (pot) I call. Other two players fold.
Turn is Ah (I turn the wheel)
BB leads out again for $8.67, here I cannot decide if I should raise to get value in now when I have the nuts as I am worries a flush card will come on the river or the board will pair. Is it correct to 3bet the turn here? I have also been told I should have maybe 3 bet the flop too with the up and down straight draw.
Thoughts? Should I have just called to hope for a good card on the river so he bets into me again?
Thanks.
