My Bets for Belmont.......Please Help

[RollerDoc]

I promise not to start another thread for a while, but I wanted to share the bets I was planning to make for tomorrow. Please tell me why this is either a good selection of bets or bad and any basic mistakes that I am making while I can still correct it.

My budget is $300.00

My picks for now are:

$170.00 – Big Brown to Win

Exacta $20 Big Brown –Denis Of Cork

Trifecta $6 Big Brown – Denis Of Cork – Tale Of Ekati

Across The Board $8 Macho Again
Across The Board $6 Ichabod Crane
Across The Board $10 Casino Drive

Total 300.00

I'm sure I will get hazed pretty bad for doing this but go ahead and fire away. I honestly would appreciate the critique and what you might do different. FYI...I do not want to move off of making Big Brown #1 pick.
