This is in contrast to the game of Chess. I am an unrated Chess player, but if I chose to compete I suspect I would come in around 1,200. I have no trouble finding Chess programs that can beat me. The best programs can beat a Grand Master. I find have yet to find Bridge software that plays as well as a good social player.
Bridge is about bidding and play.
But you do get the occasional disaster. I find it very inconvenient that this product does not provide a way to review the bidding during a long auction, to claim or concede, or to look at or save a hand at the end of play for further study. Indeed, there is also no way to enter a hand, or else I might have pitted it against Bridge Baron. Of these, I think Bridge Baron is the strongest, although it is a little subjective here. In the end, the enthusiast may end up with several of these games.
