My greatest comeback story is a live MTT, 30 players. Buyin was...t1200 at least. My memory is somewhat foggy on this.

Several loose calls and seeing too many flops left me with 70 chips at 75/150 blinds after the second merge (down to the final ten). I was able to recover (after pushing JTs and catching a T on the river to make two pair), then got short-stacked again. And again and again.

In all, I was short-stack at the final ten, 7-handed, 5-handed AND 3-handed. I ended up winning that tourney after several lucky pushes, blind-stealing and what is still, to this day, the best heads-up I've played. There was a great amount of beginner's luck involved (especially because most of those players were, and still are donks), and I've evolved much more as a poker player since then, but the story is still fun to tell.
