if lag means he is raising 1/3 of the hands you should add another (normal 6$) raising percentage of the other players and just lay this down preflop. Wait for a better hand and/or position to double up. If you are ready to go all-in after his raise you should go all-in by yourself preflop, hoping to pick up the 225 ships already in and still having a hand when being called. But I still prefer the fold preflop.
