Here are a couple of good resources for tournament info:

Expect there to be a big learning curve. Strategy and understanding *how* to play is every bit as important as handicapping. Most contests have slightly different formats so one of the key factors is figuring out what it's going to take to win or hit the board. You can look at past results or apply standard guidelines. Tournaments are far more about finding playable mid-priced horses and longshots than about picking winners. You may have to pass on a 6-1 shot you like or even a 4-1 absolute cinch because you need 10-1 winners to compete. You also need to be able to adjust your strategy based upon where you are in standings as it gets late. The biggest issue is to make the transition from looking for winners and profit (betting approach) to a tournament approach where it's more of an all or nothing. ie - You don't get rewarded for coming in 23rd out of 200 and showing a flat bet profit. You're simply not going to win tournaments with a number of solid 3-1 or even 6-1 winners - no matter how confident you are of their chances. Goes against what you're used to. At the same time, stabbing entirely at longshots won't get the job done either. You have to find the right medium - but it really is a totally different mentality than what works for betting and it takes time getting used to.
