For the short stack tourny situation Aisthesis, wouldn't the natural hand ranking system just be according to heads up showdown performance? Here's a link to the GoCee site that gives that ranking system.

As for a ranking system where there is more play after the flop, I'm not sure. Has anyone actually done that for say Heads Up Play? Or Three way play? Not that you're playing heads up but you may be likely to go heads up after your bet.

btw, I too agree with George Rice's sentiments.
