Here are just a few examples (invented--I unfortunately had no real hands against this particular guy and was sitting more or less across from him, but I did have a similar thing vs. a chronic raiser a while back and was sitting to his right):

You have KQ in MP (raiser to your left) and limp, raiser raises, 1 caller. Now even I will limp re-raise. What I don't like about being to his left in this situation is that I'm re-raising into a field of 7 other players with completely unknown hands and who certainly aren't laying down AK here, probably not AQ, etc.

In the scenario outlined, I'll probably still just flat call if there are more than 2 other limpers simply because a lot of players try to trap on big hands with position, and I again don't mind getting involved with the raiser but am worried about the rest of the table.

So, let's take KQ with a few more players seeing the flop, and I flat call to raiser's right. Flop comes K64 or whatever. Now, if raiser will frequently CB, I check. Raiser bets. Ok, now if someone else raises that bet, I just quietly fold here (I figure the minimum hand they'll have is a split pot with me, and I lose to everything else). But if the rest of the table folds or we even maybe have 1 flat caller, I'll check-raise.

What this does is get your AK (or AQ on a Q-high board) question marks out of the way by USING the raiser to find out if anyone else has a hand.

Unless someone else in the hand slow plays a monster thinking the LAG will keep betting. Either preflop or post flop, but I would be more worried about them doing it post flop.

If Im on the left and LAG raises and I reraise with KQ, most people are laying down 66 so I dont have to worry about a set in this case very often.

if Im on the right and I limp with KQ, then LAG raises..MP calls with 66, I reraise, LAG calls...66 is calling also most of the time (depending on stack sizes). And if dont hit TP, the pot is now monsterous because theres another guy o2 even 2 in the hand so I cant even CB to take it away from the LAG who probably has nothing just like me.
