On one hand, I feel like this is a fold because they're going to raise behind me a lot and I could get trapped in the pot for a bunch of bets. On the other hand, there's a ton of bets in the pot already and if I hit the GS or make a flush they'll probably all pay off and may even go off with worse hands for multiple BB.
