IMHO there is no cheating in this game, as long as nobody can see the real bids of the other players befor he/she bids. If somebody wants to use some computer programms, spreadsheeds, external advisers, Nostradamus' Prophecy or whatever, he/she should feel free to do it. Personally I can't imagine that it really guarantee a win. -- In the runs on the server where I played it initially, we didn't forbid even agreements between players - they didn't work anyway. :-)
