I wouldn’t 3-bet 4th either. Although queens are more likely than the 4-flush, a 3-bet might knock seat 7 out and you’d prefer to keep him in.

I like the idea of raising 5th. It increases your chances of winning with small two pairs (or even unimproved) and the chance that your straight will be good (if you happen to hit one of the two remaining 4s); it might get you a free card on 6th, too.

I don’t really like the bet on 6th. Aces up is his most likely hand I think, so take the free card.
