Entered this one today. Had some success at horseplayers.com and horsetourneys.com but nowhere near some of the best who are consistently among the top contenders.
I've found that focusing on who's gonna Win (Win and Place tournaments) helps with horizontals. Most people get in the habit of handicapping contenders and use contenders in their tickets instead of narrowing it down to 1 or 2 horses.
Anyway, good luck if anyone plays. There are much smaller tournaments to enter and feeders to get into bigger tournaments. I'd recommend playing in the small ones to get a feel for it if you've never played in these things before. They have great customer service IMO as well.
And don't feel bad if you you pick Zero winners. It happens to everyone including the best players. Keep punching
