Success!!!! I think I finally posted a hand history!!!! This is exciting and there should be plenty more where this came from.


So this was a really tough spot for me, because both villains seemed to be competent regulars multitabling. Villain 1 (UTG opener) was playing TAGish but I don't have many hands on him. Villain two always plays a ton of tables and is a nit playing 12/7/1.6, so once he shipped it on the turn in a multiway pot I really thought the best play was to fold, but my damn fingers wouldn't let me and I called it off. What do you guys think I should have done different here?
