Programmer can use any language they want, as long as program is easily usable.
I have software that makes the gameplay decisions for the hand. The program you wire must:
1. Click a button to make the bet for the hand.
2. read cards off the screen
3. enter cards into the other program that will tell how to play the hand.
4. play the hand accordingly.
There are also some special conditions that overrule the other software. I will specify these rules and also give the site the game will be played on via PM.
