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.
