I'm playing poker w/ some of the regulars. Frank hands me a credit card to make a preflop call and I throw in $10 for him, taking $1 from the table as change (we're using money instead of chips). A streets later, it's the river and everyone's checked. Frank has not hit his KT of clubs and says to me, "Do what you do best." I assume he means steal this pot and I look over the board. There's 4 to a spade flush on board and I consider how much to bet.
