Ah, yes - Rubber is quite a different game. It's possible to play duplicate with only four players these days by using Bridge Base Online: they have a database of old competitions, their deals and scores, so you can play against a virtual room. Less fun playing online than round a kitchen table, though. I also play a version of Chicago bridge where you play IMPed against a par score calculated from your partnership's number of high card points[0]. That introduces some of the need for aggressive bidding that can be missing from (non-gambling) Rubber and is a fabulous game: nearly as much fun as a decent club duplicate. I've never seen this variant played or taught outside my own social circle, though we didn't invent it. [0]: http://maproom.co.uk/useful/bridge.html http://maproom.co.uk/useful/bridge.html
