Robots on BBO
Players are permitted to rent a robot to play with in pairs tournaments. This is a service offered by BBO, and costs $0.25/tournament. The robot plays a natural 2/1 system, with what appears to be standard carding and signals (high encouraging), but don't trust this completely, as it can sometimes be random.
When playing in a tournament, use a mouse pointer to hover over a bid which the robot makes, or a bid you want to potentially make, to see the description of how the robot will interpret the bid. This also works with a finger tap on a mobile device (phone/ipad), but be careful not to press the bid, unless you have the "confirm bids" option enabled in your BBO settings.
You can find their system notes below.
To enter with a robot, find the tournament in Virtual Clubs, and on the registration screen will be a blue button which says "Play with Robot (0.25 BB$)". Click this, and you'll be registered to play.
If you want to change your mind, simply click on the "Cancel" button, and deregister.
