Betting Big Brown is a tricky proposition. The galloping UPS ad is expected to go off at 1-5 odds, meaning you'd have to risk $5 to win $1. That means that the only bets worth making are exactas, trifectas, and the like.

The Belmont Stakes begin at 5:25 p.m., so get your bets in early.

For neophyte gamblers, here's a guide for what to say at the window.

If you're looking for a good exacta pairing, you could do worse than Denis of Cork.

Denis of Cork's trainer, transplanted Irishman David Carroll, knows every inch of Belmont Park. Carroll, 48, was the exercise rider for 1989 Belmont winner Easy Goer during a six-year stint under Shug McGaughey. Easy Goer derailed his archrival Sunday Silence's Triple Crown bid, but Carroll isn't predicting his colt can knock off Big Brown.
