The main problem is that you're only bringing 20 big bets to the table and making it sound like that might be your entire bankroll. If this is the case, you should not only fold but get out of the game. That's a completely different subject though.

Assuming you aren't playing with scared money and have enough to reload (since the normal buyin for a 100/200 game is $4000 on most OL servers) You should limp. If you raise you *might* force the sb out. I have played with 10Gunman to tell you he knows there aren't many hands he'd fold in that situation getting over 5 to 1 on his money, so raising seems counterproductive, you won't be able to isolate unless 10Gunman picked up one of the worst hands in the deck.

I call -- any ace four handed playing with a known limper is worth playing. You have position for the entire hand and are getting 3-1 on your money as of now. Easy call for me.
