re: Poker & Preflop bet 3x BB + every limper..
well of course that this tactic, if it can be called tactic, only works if no one raised in fron of you, if the pot is raised you need to 3 bet if you want to raise him, and you do that 2.5-3x size of his opening, or you just call his raise and play IP against him post flop.
The point of what you were asking about was the opening bet size, when is jour time to act and you want to raise you set 3bb size if the pot is unopened or if its already limped you add 1 bb for each limper already in pot. So actually its only not working when you're UTG because there cant be limpers in front of you. There is a slight addition to the rule for adding one bb more if you will play the hand OOP (out of position) post flop... for example you are in SB, co and btn limped so there are 2 limpers in front of you and if you want to raise you should raise 3bb+2bb+1bb=6bb 3bb is original bet size, 2 bb is for 2 limpers before you and additinal 1bb is because you will play that hand OOP post flop...
