Cons: The button's hand is strong, or plays very well multiway (or both): he's raising four limpers. Also, you're out of position the rest of the way.

Pros: It's multiway, and your hand plays pretty well multiway.

However, I'm not sure you want to be in the habit of playing suited one-gappers for two bets (well, 1.5 bets) from the worst betting position on the table. I'd guess it could be marginally profitable at best if you're easily outplaying the field, but more likely you'll miss flop after flop in this situation and end up costing yourself more than that big pot you win with the SF.

Another problem is that the pot will be big here (11.5 SB if you call), and if you do catch part of the flop (say you flop top pair and some backdoor draws), you'll be tied to the pot and end up putting much more money in than your 1.5 SB. There's potential for pretty huge variance in making this play, and I'm not sure it's finally +EV.
