You're playing above your bankroll, bad idea.

If this is a limit game you're certainly costing yourself money. In a NL game you're playing short stack poker and costing yourself the chance to learn to play well with deeper money.

IMHO, short buy-ins should be banned from the NL table. Online there is no cause for them. Actually, it's due to a lack of creativity that we even bother with stack sizes at all online. A 100xBB or 200xBB per hand cap would create a great big bet game and give everyone a fair chance.

I'm surprised that more people don't abuse the short buy-in at NL tables like the matrix guy and his 3 accounts did/does at the Party games.
