My standard opening pre-flop raise is 3xbb + 1xbb for each limper in the pot ahead of me, up to 5x. Some people say they raise to start building a potentially big pot. I, on the other hand, raise to try to limit the number of players in the pot. The more players in the pot, the higher the possibility and probability that someone will hit bingo with an inferior starting hand. I raise to try to keep those bingo players out of the hand.
That is my standard play. With pocket aces, I make my standard raise of 3x + 1x for each limper, so as not to telegraph the strength of my hand. Like with any other hand, I want to limit the number players involved in the hand to reduce the chances of someone getting lucky on me. The
odds of pocket aces holding up starts to drop considerably with each additional player that comes into the pot. The key is to try to limit the number of players in the pot, but not to chase everyone out of the hand, which is why just open shoving is probably not the best idea, unless you often play other
hands that way. If the pot is raised in front of me, then I am going to 3-bet. If I raise and someone 3-bets, then I'm going to 4-bet. I am basically going to keep re-raising until I feel that my opponent is not folding, or I feel that the pot is big enough that I will be satisfied taking it down at that point. That is the point at which I will go all-in.
