You were correct to not 3-bet the flop.

Your chance of making the nut flush by the river were ~ 2:1, so you needed at least 3 opponents to still be in the hand to give you a sufficient equity edge to make further flop bets profitable.

If the turn had been checked to you, you should have taken a free card. The chances of making your flush on the river had now become ~ 4:1, so you would have needed 5 opponents to call a turn bet to make it profitable.

I think it was worth calling the flop bet to see the turn.

BB was probably betting with either top pair or a straight draw. The pot was offering 7.5:1 to call, and the chance of your spiking an A or K was about 6.5:1.

On the turn, it probably would have been best to fold to a further bet from BB.

The 6 made it possible for BB to have made a straight leaving you drawing dead. Also if BB only had top pair, your odds of pairing your A or K were now 7:1 and the pot was small.

Finally another reason for considering folding on the turn is that a lot of players like to play hands like Ax.

That increases the chance that BB could have been betting with a hand like A2,A5 or A8. Then if you had spiked your A on the river, you would have been behind to his 2 pair.
