Everybody likes Poker nowadays. Bogislaw ("Boker") von Schönfeldt, our
expert, will gladly open a Poker table. Most likely a warm-up on
Thursday night and some more on Friday and Saturday after midnight,
when dip is over.
Depending on whether people like the idea and join in, he might even organise a one- or two-round tournament on Saturday afternoon - for those who sit out the 4th dip round. (Most likely 5 EUR buy-in no-limit Texas Hold'em.)
Note that we can't allow for "big money" gambling, and we can't allow underage players to bet money. This is a) for ethical reasons and b) for legal reasons.
