If the table is good, I'll stick around. But building a huge stack in a cash game doesn't do much except possibly intimidate other huge stacks. But if you're going up against someone with 100BB, they shouldn't view you any different than anyone else who has equal or larger stacks than them. So it just depends on the table.

If I have 200BB and the person to my immediate left also has 200BB, i'll leave. But I'm more likely to stick around if he's on my right. So like everything in poker, it's situational.
