Was watching some vugraph just now. I am not sure whether jurisdiction is relevant to the question.

The strategy suggested was that if you are far behind in a match that it is good to agree that one pair will play their usual game and the other will try for everything.

Now, this, to me, sounds like a change in agreements. Is this something that would need to be disclosed to the opponents?

Yes, I believe so. But I seem to have read somewhere that while you have to tell your current opponents your style, you do not have to tell them your team-mates' style. Comments welcome.

I would consider it general bridge knowledge, that when you are behind, evaluating your hands more aggressively could be part of the strategy.

If they know that they are far behind, than you know that you are in front.

More interesting is the question if they are allowed to chance agreements, esp. in events where you have to enter your system description / CC in advance so that everyone can prepare defenses.

It may be general bridge knowledge, but if our team has the specific agreement that Kenberg and I keep playing normal bridge while Dickhy/Willo49 go for swings, then I think it needs to be disclosed.
