When you are the only human player, you will play with a computer partner (for example as a North/South team). First you will bid and play the game, then a North/South computer team will bid and play the same game. The scores are then compared and the results are recorded. As you continue to play you will be able to see that your game is improving. If there is more than one human player you can either play as partners or as opponents. The computer plays an excellent game of duplicate bridge. Don't be surprised if it ties you or beats you. By the way, Let's Play Bridge does not cheat.
