About 80% of these 2v2 games end in the first 5-10 moves, and as far as I see, those very short checkmates could be avoided with placing the partners next to each other. This would make the bishops harder to activate, for instance, moving your king's pawn would open only one diagonal against an opponent, the second would aim at your mate. The kings could castle into real safety, where there are less diagonals to use against one's king.
Let's say
XXXXXXXX
Stronger 2
XXXXXXXX
Weaker 4
Stronger 3
XXXXXXXX
Weaker 1
XXXXXXXX
Matching: The highest and lowest 'elo' players are mates.
Moves could be:
1) Weaker 1 - Stronger 2 - Stronger 3 - Weaker 4,
2) -||-
(or whatever)
This could reduce the number of very short games, and could also lead to more tactical games, where the knights and pawns have more role.What do you think?
