[Codo]

Surely this had been discussed several times, but I cannnot find it, so here is my question:

You play with and against pick up partners. You give the announcement: Advanced only (Or experts or whatever).
Now, after a few boards, you get to know, that you have two good players at your table and a real bad one.

Up to now, I let anybody play and sooner or later, the gifted opponent will leave and the novice will stay. The next advandced player arrives, some boards, same result: bye bye.

I would very much prefer, if the novice had been able to see, that he/she does not fit to this table. But this never happens.

So what to do? Sit and be gentle? Leave the table yourself? Just kick the beginner? Talk to him/her?

Other ideas?
