I'd say the $110 player is likely to be one of:
a) a TAG who has taken a flop with a c-bet.
b) a passive player who has been lucky enough to win a small pot.

Here I'd put my money on a).

The $200 player has most likely not participated in many pots, but has still managed to get a stacking (otherwise his stack would be $194 or $232 or something - not sure if Fnord meant it to be that specific). He could be anything, but I'd say most likely:
a) a maniac who rivered his flush draw or something.
b) a nutcamper who stacked a fish.
d) any player who hit a lucky hand soon after sitting down.

I'd say the $110 is more likely to be the solid player. Anyone with a modicum of aggression could easily be the $200 stack if they hit a lucky hand.
