With the 27th edition of the Vis Moot under way (and the 10th in which I am involved as coach and arbitrator), it has only taken five days for my annual interaction with a colleague asking me why I coach our Vis Moot team, and what is the point. Indeed, at first glance it may seem counter-productive: the University gives me 16 hours per term to coach the team, and I usually spend 20 hours in the first two weeks of preparation - which means that I basically take time off research or rest to coach the team; if (rectius, when) we do not win I am responsible, but the credit for any success goes to the students (and rightly so); I am not a PhD student and I do not need to go to Vienna with a team to enlarge my network - at this point in my career, I pretty much know who I need to know and I can be introduced to those I do not, and my yearly trip to Vienna is sufficiently justified by the desire to watch my team competing, arbitrating one or two good teams, and ingest as many wienerschnitzel...
