I really despise these stupid miniraise situations that I tend to see just about every hand at the 25NL and 50NL. Sometimes it means nuts other times it means air. Anyways, with that said do I 3 bet this (all in) or flat call and re-evaluate turn.

I considered myself to have 9 hearts - 2 aces - 4 4s totalling at 15 outs vs. a set. Even more outs vs. 2 pair (counterfit it) but only 7 outs to a made flush which seemed like a very likely holding.

I moved all in as a 'semi-bluff' i guess you could call it but do you think there's a better line?
