re: Poker & Percent stack to risk against small stacks?
Harrington called it fly swatting, and would call with most hands if it cost 10% or less of his stack.
This was a late tournament play though. I don't care if a shorty goes out early, as he'll go out anyway. Early on I just care about getting chips.
When we're at the end of the game and knocking people out to move up in the money is important, then calling shorties light to KO them has a bit more meaning. That is, early on you make plays based on getting chips, while late in a game you make plays based on payout.
