It is like the first solution I have tried, but I had only 1-ply minimax (so 
max :-)), to avoid to choose between only 10 moves at first (you have to have 
a good way to do it, we haven't).
With 1-ply minimax, it does not give impressive results, and can even be 
worst, because clients have not the same speed, so one move can be more 
deeply explored and reported as weaker, even if it is better...
