This is unsolved for a long time in MathOverflow. It's a card-game-problem, so I think it's more appropriate for cstheory, but I'm not sure, so I post a meta problem here to ensure.

I think that reposting is fine, but if you repost, please do the following:

  • Link in both directions.
  • Try to take care of the questions on both sites. That is, if you receive an answer on one site, let the users of the other site know. I understand this is not always possible, though.

You may want to include Guillaume Brunerie’s reformulation in natural language in the comment to the question on MathOverflow; it helped me understand the rules.

  • $\begingroup$ I'll do tomorrow. I'll try, but I think it's few probability that I will receive an answer from MO. $\endgroup$

  • $\begingroup$ I've migrated, roughly mixed with GB's reformulation. You can view it. $\endgroup$
