I'm coming up with 99 as having a fraction over 20% equity against those four hands (third best) with PokerStove. Change the JTo to 87o and 99 becomes a solid favorite. You're not going to run into too many lineups where you're not at least break-even unless people are limping hands like TT and AK (which can happen) and you're sometimes going to run into lineups where you have much better than average equity.

So, people who think that you should raise any time you have an equity edge do have a point. I just happen to think that the game conditions as described probably put you into a few too many reverse implied odds situations so that you'll probably underperform you equity if you raise. Still, I think it's a close decision. If raising is actually the better option, it probably isn't +EV by that much more over just calling and comes with a sharp increase in variance. It's quite possible that someone who likes playing LAGgy should probably raise and someone who likes playing tighter should just call. I do know that David Sklansky has said that weak-tight play is close to correct in truly wild and crazy games.

I would consider not raising the flop, but it depends upon my read of the initial bettor and the people behind me. I can't really explain how that all works, though.
