OK, thanks. It's good to know we hadn't misunderstood this aspect of the instructions.
It's a pity that BridgePal does not properly support sessions with a very small number of players, because it is through these that individuals can demonstrate to themselves that the system works before they make a major proposal to their club. (As you know, it is so inexpensive for someone to download the software, and borrow a WiFi router and a couple of Android handsets.)
My wife and I play in a couple of leagues in Surrey which take place in people's homes: just two teams of four, in which you play against one pair in the first half, then the other opposing pair in the second half.It would be nice to have BridgePal support this sort of match.
We also have social bridge when we have just four players, in which we compete on the basis of the optimal contract calculated for the Hand Record. If you make the Optimal Contract, then neither side wins the board. If you exceed the optimal score, the board is a victory to your pair; if you do worse, the board is a victory to the opposing pair. Simple, but fun. It would be wonderful to have BridgePal support that sort of non-duplicate game.
