That’s a classic tough spot — pocket Jacks can be one of the most uncomfortable hands to play, especially early in a tournament when you’re deep-stacked and facing an all-in.
Personally, my decision depends on several factors:
Stack sizes – If the all-in came from a short stack (say, under 15 BB), I’m more likely to call.
Position and player tendencies – If it’s a loose or desperate player jamming early, I might lean toward calling. If it’s a tight player shoving from early position, I’d consider folding.
Tournament stage – Early game? I might fold and wait for a better, less risky spot. Late game with shorter stacks? I'm more inclined to take the flip.
So folding Jacks there isn't necessarily wrong — sometimes it’s the disciplined play. But don’t let the uncertainty eat at you; the key is to keep learning from each spot and trusting your process.
