1) I don't understand the hostility on these sites. Is it really that bad to post a hand simply for the purposes of showing a win?
2) I didn't think it counted as a "limp behind" when I'm on the button, holding a drawing hand, and UTG already limped into the pot. It is?
It's not hostility, it's just the policy here that we keep threads organized. The BC is for strategy, and you weren't asking any questions or trying to initiate discussion, it was a brag post about stacking a fish so it belongs in wins and fails.
Limping behind is when you limp behind other limpers, which differs from open limping where you're the first limper.
After about ~300 hands last night and another few days of poker under my belt, I realize how mainstream this hand was and definitely wouldn't have created the thread if I could do it over again. These things are going to happen.
I've really tightened my full ring game up over the last few hundred hands, though. I fold in so many opportunities where I would have leaked money previously.
