question about getting checks..

[nickcage100]

from a sportsbook.
I have 3 options when I get a check from my book.
1. go to the bank and cash it.
2. go to the bank and deposit it.
3. go to the bank and deposit part of it and
get some cash back.

What is the best way to do it if I don't want anybody to find out I'm making money
w/ sports betting. Also, should I keep the checks under a certain amount?

thanks in advance
