Card counting

I burned through Bringing Down the House like so many hands of blackjack. Some clumsy, overheated prose, but the story is undeniably interesting. A bunch of MIT geeks learn to count cards, devise a sophisticated team counting scheme, and win millions from casinos around the U.S., especially those in Vegas. Includes mention of a faux riverboast casino in Illinois that I visited once or twice.
Especially appealing for geeks as it's one of the few stories where math nerds can parlay their smarts into dating nubile young NFL cheerleaders.
