Should I have called here? I feel like I made the right move by folding, but as always am frustrated that I missed tripling up. I only had about $15 total, so I would've of course been all-in.

I just figured one of them had an overpair. Had Seat 5 not called, I would have... Seat 4 is hyper-aggressive, pushing all-in almost whenever he senses weakness. I knew he'd get busted.

Seat 5 is a very collected player, I respect him.

I would've gotten around 2.5-1 on my money had I made the call, but I knew I was drawing against at least 1 made hand.
