Why is the "Bet Pot" amount larger than what appears to be in the pot?

[dubiousdrift]

Another thing to note is that betting pot in this way lays exactly 2-1 odds back to an original bettor.

Take for example a pot of 100 (pennies or dollars) on the flop. Someone bets 1/2 pot of 50 to you. You bet pot and it folds back to the original raiser who is now getting 2-1 to call your raise.

100 (pot) + 50 (bet) = 150
(youre getting 3-1 on a call)

you bet pot, which is:
50 (call) + 200 (raise of the size of the pot after your call) = 250

The original bettor now must call 200 for a 400 pot, getting exactly 2-1 pot odds for the call.

Hope this helps someone.
