Both MP3 and CO are huge fish, i saw them make some very bad play, like going broke with top pair 7 kicker or bet 3 street with middle pair.
So i think my preflop call is ok, the flop call is questionable, but i think still ok.
After MP3 3bet on flop and CO goes allin i think i still had the odds for a call, but i didn't know the rules!! CO had a bit more than MP3's 3bet was so CO's all-in opened the betting again or not?
Because if it has opened, then i have to fear that MP3 is gonna shove after my call.
There was some rule that only at least two times the original raise counts as a raise and in cases like this the allin doesn't opens the betting again. I don't know if i remember this from limit holdem or is it the rule in no limit too.
So i need some assistance in learning the rules of the game that i has been playing for a year now 
Thanks,
