How to exploit an annoying LAG

[DickieBets]

I had position on a player who was roughly 30/20 . He was raising from position usually - so obviously knew what he was doing - my guess is that he was a CardRunners member. The problem for me was that I was trying to play a TAG style - but because of his raises - I was forced to tighten up - whenever I did have a hand and 3-bet - it killed any action and he folded . Once I loosened up my 3-betting range - then he started calling and I was weak - and without hitting good flops was vulnerable.

So, is the best thing to do - just leave ? or is there a way to exploit this? In hindsight, I've been thinking that 3-betting once in a while with good hands might be good along with just calling with premium hands, encouraging more action and hoping he c-bets into me - but I dread multiple callers in a pot when I have a hand like pocket Aces, for example.

Any ideas ?
