Early in tourney, flop a set against a 3-flush

[flytrap]

It's the third hand of a 50+5 party poker one table sng. Blinds are 10/15. I have JJ in utg+1. I raise to 45, the button and sb call. We all have 950ish in chips.

You're getting ~ 6 to 1, so I call. You may still be ahead, and even if there is a flush, you have seven outs (3 aces, 1 jack, 3 fours), not including a running pair.
