I know what you are trying to do - and that is get a game to start with 1,000 points each - but that is not was is being done here (Fencer will hopefully get it set up do to this at some point.)
What is being done is a game that starts with 20,000 points WITH a minimum first bet of 19,000.... which is similar to a game that starts with 1,000 points - but not the same.
If you want everyone to bid above 19,001 in the first bid - then I would think that would be inportant information to have in the rules of the game before it starts.
