As I write this question, Ian Nepomniatchi is leading the ongoing Candidates tournament by a substantial margin. Since it's a winner-takes-all tournament, everyone else needs Nepomniatchi to lose.

Are the other players allowed to discuss how to achieve this collective goal? For example can they suggest openings to whoever is playing Nepomniatchi, or discuss whether one should take risks and possibly lose in return for a chance at winning (as Rapport did in his game against Nepomniatchi)?
