Puckish: I would consider every specific advice over a certain move like "go, double now" probably breaking the rules and every general advice like "you all maybe should'nt play too conservative, we need a win to advance" perfectly acceptable. The former is just too specific, giving advice on a single move - and is not comparable to a golfer or any other sportsman for the reasons you gave yourself. The latter is simply a general advice about big-picture strategy, something every team should be allowed to discuss and agree upon. But that is just my "feeling" and others might draw different lines.
(verberg) Zin in een vlugge partij die gegarandeerd binnen 2 uur klaar is? Zet dan in de gewenste spelsoort een nieuwe partij op en stel de tijd in op 0 dagen / 1 uur, de extra tijd op 0 dagen / 0 uur en de limiet op 0 dagen / 1 uur. (TeamBundy) (laat alle tips zien)
