There was an article in Cardplayer a few months ago that posed the question. Would you bust your own Grandma? Assuming that she was sitting at the table with you, at stakes that you consider profitable (not fun), would you exploit her game and try to take your share of her SS check, or would you play 'nice'? Your answer is meant to indicate whether or not you have the mentality to be a pro.
As for me, I'd go for the throat to start, but then the guilt would set in and I'd back off. I might even dump to her. Guess I'm just a poker player, not made to be a pro.
