N/S started the defense decently enough but couldn't unravel 6 tricks. UDCA agreements for defense.
Where do you see chances for either N or S to do better? S doesn't need to play the 3rd club, it seems like, but it's not clear which red suit to switch to and on the actual lie it doesn't hurt. I was south, that's why I played the 3rd club, to let partner decide, though I know it sets up the 13th club. How clear should it be that we needed to attack both red suits, or hearts first?
