I wouldn't say it was a bad fold, I think its probably the correct move 90% of the time in that spot. Just sucks that you were up against some overplaying tards. Btw I'm prob not good enough to fold there, I'm a POW. Definitely wasn't the worst fold you've ever made, you're being very results oriented here.
If you were right, and he had the boat, (which he should have a LOT of the time) then that may well have been one of the best folds you've ever made. So I say congratz sir, on a very disciplined fold!
