user15223: Inspired by How much stronger is a team of GMs compared to a single GM?
All the chess matches I'm aware of have been 1v1. There have been team competitions such as the Olympiads, but I am not sure if you are allowed to discuss moves with your teammates in Olympiads. I assume not since news reports don't usually mention the teammates discussing. If so then Olympiads are just a series of 1v1 games.
I am wondering if there has ever been a consultation chess tournament/match of the kind where a group of players play against another group of players, and both sides are able to talk and discuss moves before they are made. If so, I'd like details of the tournament/match.
A few close cases:

Hand and brain chess, although the hand and brain are not supposed to talk.
Kasparov vs. the world was sort of a consultation game, but it was also a correspondence game since the time control was very long. I am looking only for OTB games.
another close case: pair matches eg this or the mixed sex version, although the teams are not supposed to talk.


user17126: A chessgames.com user has made a compilation of consultation games. For example, it contains Lasker / Pillsbury vs Steinitz / Chigorin. According to a comment by user TheFocus, it was "played in St. Petersburg, Russia on January 29, 1896."
