Hey man, hope you enjoy our forums.
"Checkings" refers to the amount of points you have on hand, and that aren't in the bank. "Savings" refers to the amount that is in the bank and is gaining interest. You can transfar points back and fourth between these by following the steps in the Bank(top right hand corner of the page).
If you bet 50 points on 2/1 odds, and if you win, you will get 100 points back. If you lose, you lose the 50 points. If it were 3/1, you would have won 150.
Hope I have helped.
