About the robots

• The robots used are GIB robots.
• This event utilizes Advanced Robots.
• The robots play a modified 2/1 system.
• This is a link to robot's system notes. The robots sometimes deviate from notes if simulations lead them to other conclusions.
• The robot's understanding of what a bid means can be seen by clicking on the highlighted bid.
• When it is a player's turn to bid, the player can see what robots think a bid means before making the bid by mousing over the bid in the bidding diagram (before clicking to make that bid).
