Well I'm currently a shortstacker at 50nl 6max. I'd have to agree that most SS regs are horrible players, but really no worse than any other regs I encounter.

As has been said, don't steal too light if they're 3bet shove happy, or steal often if they are really tight. Shove over if they steal light and fold to shoves with hands lacking in the nec. equity to call, obv. Acknowledge that they are essentially playing a different game than you are. Other than that, it's super villain dependent and not really that difficult a strategy to counteract. Just understand that you're constantly going to get into flips and 70/30s preflop which is, in certain ways, appears high variance.

Do yourself a favor and PokerStove some typical shoving ranges and find the range of hands you can call with and junk.
