I've seen that, too, but, just the other night, two of the good players (not great, but good) got into some kind of buy-in frenzy and both had over $3,000 in front of them in a 2/5 game.

I also think your 12 BB in a cash game is way too low. I think it's suboptimal to play with less than 100 BB--in NL, anyway. I'll have to admit that I don't even pay attention to the limit games, so I have no clue what really happens there, although I do think you can definitely get by pretty optimally with a much shorter stack.

Anyhow, it's definitely just a rule of thumb, and I honestly don't see much point in playing 2/5, for example, with a stack of $3,000. I honestly don't LIKE having more than $1,500 in front of me, although it's probably actually a weakness, unless I have almost everyone well-covered.

And, I agree, loose morons on a rush can get way up there, but they usually lose it all back the same night. Honestly, though, I think I've seen at least an equal number of good players on a rush with big stacks--and they generally actually go home with it.
