Matchpoints, you're vul, they're not
System is weak NT with 5cM.
Our auction was 1C-1S; 2H-3D*; 4C-4S and I then had to consider that it's matchpoints and 620/650 scores better than 600 (stupid game, MPs), so I passed. At teams I would of course bid 5C and I guess partner might well then raise to 6.
Bonus puzzle for I/A: how to play 4S on the lead of D4 (4th, top from rubbish) to the 10 and Q?
