pocket pairs.

Do you guys raise or limp with pocket pairs?

Lets say you have a tight image, 25/50 blinds, 1500 chips do you raise, limp, or fold 22-77, early, middle, and late position?

If you limp is this not telling them you have a pocket pair? I mean you have a tight image so big hands, which is all you play, would be raised up, bad hands would be folded.

If you raise aren't you putting more chips in the pot than you should?
You're trying to see a cheap flop and hit a set, no? There's obviously no reason to raise to steal blinds either, so everyone folding won't do you good.

This applys to sng's, but I would like to read opinions for these same situations in tournaments as well.

10 or higher I usually raise what i feel is appropriate for how the other players have been playing, however most the time I just limp with a lower pocket pair and hope to catch, or bet if I think it's obvious that the other players have not hit a thing... then again I am no poker pro, how do you usually play yours?

I don't like going to the flop and preparing to fold if you didn't hit your set. In early position, you should dump low PP, from middle it's worth a raise from 99+ (77+ if you have a solid image). With your tight image, you could be representing AQ+ or 10+. If you hit the board hard, then great. If you have second pair, try a continuation bet to represent that top pair or an overpair.

I like to raise them and limp at about 50% clip to mix up my play depending on position.

The general wisdom is that any hand worth playing is worth playing for a raise, and that limping kills kittens. So if you're not going to raise 'em, dump 'em, and that will usually be correct in early position. If you're at a very loose passive table where preflop raises are rare and lots of people see every flop, it's probably OK to limp, but you don't want to limp with a small pocket pair or otherwise marginal hand and then get raised and have to fold, or incorrectly call.

Anything less than 77 I would fold from early, call from Middle and raise from late. 8's and 9's I would call from early and raise from middle onwards. 10's and above I would raise from early.

This is my rule of thumb but you have tomake adjustments depending on the dynamics of the table and the other players style of play.

Firstly I'm assuming we're talking about only if it's been folded to us?

Early levels of a SNG (or MTT if only 1500 chip starting stack).. I'm dumping them in early position & raising from HJ, CO, BTN & SB.
Hitting a set is obvious ideal result but if we're raising & end up going heads up with BB, then we can also represent on many flops we feel miss the BB (ie. we can cbet an A or K flop & take it down a large majority of the time).

I will usually fold out of position with any small pair. If I can get a cheap flop in late position I will try and see at least the flop. Bin burned too many times trying to make something out of nothing.

AA, KK, QQ I do a big bet just to take the blinds, on JJ, 10 10, 99 I raise, under 9s I limp in and do set minning.

If is folded to me, I'll raise, if I'm UTG that depends on what pair i'm holding.

?? But you shipped 30bb's in early levels w 88 when I raised up UTG & UTG+1 flatted, lol (btw.. I mucked JJ there, & utg+1 makes the call & also holds 88 for a chop.... sigh... 88 wtf?)
