I play on UB, and have seen an explosion in the number of people entering low/micro limit ring games short stacked. At a $10NLR it's not uncommon to see 2-3 people seated with $2.

They all play exactly the same...with a non-paired hand, pre-flop, they fold everything below AJo, then with AJo and up they go all in. For paired hands, they push with everything 88 and above. I have seen them limp down to 55 and push if raised. The only variance to this is when they are in the bb. From there, if the hand has been limped to them, they will automatically push if they hit top pair or better regardless of the kicker.

The other thing that is exactly the same for all of them is what they do after winning a hand or losing a hand. Losing a hand means they buy back in for another $2. Once they win a hand they stay until the blinds return to them, and then leave the table regardless of how many times they lost their original buy in.

I generally play a 6 ring table, but have looked in the 10 ring games and usually see 4 or more people with a stack of $2 or less.

If this were just occasionally happening I wouldn't think anything about it, but I have watched it go from a person here or there to 1/2 the table or more pretty consistently.

On a side note, this style of play is extremely exploitable. And what's even better is it effects everyone at the table allowing me to pick up all kinds of pots, and giving me easy decisions to make preflop.
