Fold preflop as default play.

you could look at it a couple ways:
1) As a rough guideline, Bill Boston's book KKT9 as top 55% of hands for tightish fullring game, and stealing w that range is too loose for most games

2) you could look at its equity. So, vs. random hand hot/cold you're even money vs. a top 25% hand and around a 42-57% (or 1.35 to 1) dog. Comparing this to limit holdem, for example, makes your hand roughly equivalent to say T6s, Q5o, or 22.

3) you might argue that with that equity, you are getting odds and have positon so you can play it. But that means that the blinds are also getting odds and so are much less likely to fold. sort of equivalent to LHE when blinds defend super loose

4) But those equities only show hot/cold. When actually playing, your hand is sorta like 22 from LHE: it is not in bad shape equity wise to many hands, can hit big, will often be ahead on the flop but opponets will always have outs, but most of the time won't know where it stands. as a result you are at a playing disadvantage. Here for example, you flopped the most likely flop you would expect: 2 low cards, no set and you have a tough time on the flop.

5) all that said, there are times you steal here: when blinds don't defend correctly, play bad postflop, when fits into overall metagame strategy, etc.
