Pre-flop Theory Question

[TTChamp]

I'm not sure I totally understand your question.

I have been playing sort handed lately, so in my book if you are first in, you always want to raise (I think the same is true first in from late position in a full game).

I get the geeling that you are talking about the situation where you have a hand like T9s in middle position in a full game. No one else has come in and you want to limp. In those types of situations, the expectation of limping vs. raising is highly dependent on the players to your left.

Is the BB a call down artist who will go to SD with K high? Is the player to your left a smart LAG who will 3 bet you and bet every street. Get what I'm saying?

Another improtant factor is how many players are acting after you. From early postion a rasie with T9s is much worse expectation wise (metagame considerations aside) than a raise first in form the button with T9s. IMO there is no time where it is correct to limp first in from the Button or CO.

Looking back at your post you may be talking about any time you want to limp even if others are in the pot. If 5 players have limped behind you, then raising with A2s would be a big mistake.
