I would like to conclude on the topic. I endende up with a very simple sum of hascard as indikator: Rand=hascard(east,2C)+hascard(east,3S)+hascard(east,4D)+hascard(east,5H)+hascard(east,6D)+hascard(east,7S)+hascard(west,2H)+hascard(west,3C)+hascard(west,4H)+hascard(west,5S)+hascard(west,6C)+hascard(west,7D) Rand is then binomial(12,25%) Strictly speaking the indicators are not independent, since they depend on the conditions for the hands in general but I have testet this on a simulation and absolutely no problem. Rand also have some slight correlation to the hand you are dealt, but I have never thought of that in the examples I have tried. One example where I use this is: SkipSmall=((Rand>=2) and (hcp(north)+hcp(south)<=24)) Just to giv you one specific. Thanks all for the warm welcome in the forum. Jørn
