You beat a lagg by semibluffing draws a little harder, and extending a large length of rope when the turn or river brings it. Act scared of coordinations that hit you when there's a big pile built from semi bluff in the middle. Lagg's can't resist taking stabs at huge pots when you act weak on coordinating boards, so it's good to build a chunk in the middle before you're made. You lose value on the semibluff, but you gain it back through implied odds on the lagg.
Another thing to do, is raise rag connectors into the lagg. Since laggs will float on pairs, you can extract a lot from them by catching good hands with connectors. This sounds like outlagging the lagg, but lagg is more than preflop. Lagg is an aggressive style all around. You can still maintain Tagg status by doing this. You're essentially mimicking the lagg preflop and then picking your battles when you flop strong. You need to catch the lagg by surprise with a nice hit, and he'll be less likely to float on you as much in the future.
There are very simple adjustments to make which will pwn a lagg, but most taggs just outright refuse to make them and allow the lagg to roam around and build stacks off of them.
