I pounded chalk on Curlin in the Ark Derby at even odds. He was the biggest lock of the day. But, it was more of a get out than it was a "strategic" play of the day. It depends on the chalk...some are worth putting a little more of your bankroll on because of their lower odds. To get the return you want.
A wise sage once told me, ask yourself, "How much money do you want to make today?" Take your best horse, decide how much you need to bet to make that and lay it down. Over time it should be a winning strategy. At least a break even strategy
