In high school I played on a chess team, but that was fairly straightforward because there were no rating restrictions for teams. Every team just grabbed the 5 strongest players and then ordered them by strength.
In most other team tournaments (except for the Chess Olympiad), there is a rating limit (i.e. the average rating of the 4 players must be less than or equal to the limit). Additionally, most team tournaments are comprised of teams of 4 players.
That was all a build up to a request for the best strategy for a team of 4 in terms of ratings. Given a rating limit of 2000 (as it is in this upcoming tournament), what are the best strategies to create a highly competitive team? Similarly, what are the average ratings on each board?
For example, a team of 4 equal rated players (2000, 2000, 2000, and 2000) would likely be at a disadvantage on the top 2 boards, but would most likely have a rating edge on the lower boards. On the other hand, a top heavy team (2500, 2000, 1800, 1700) would be more likely to have an edge on the top board, but at the cost of the second board.
A perfect answer would draw on statistics from past tournaments, but I would love to have personal anecdotes as well!
