I may be the only one, but I think third is a fine spot to jam once in a while. The only card out that weakens your draw it a lone Seven, and there's a good chance your opponents are holding each others' outs.

Nothing in poker is something you ought to always do, but I don't mind occasionally jamming with a live compound draw like this.

Fourth came down great, since your hand was not played like a three-flush, anybody hitting two pair in this big pot will probably pay off if you flush out on Fifth. This is precisely why you occasionally want to jam Third with a hand like this.

It's analogous to the Holdem play of raising in early position with a gapper or little pair. It increases your bluff equity with scare cards and makes it possible to get paid off when you make a big concealed hand.
