north:
♠54
♥9765
♣KQJ1074
♦6

south:
♠AK107
♥AKQ2
♣2
♦AKJ2

vul:both.
Both N and S are robots.It's a easy small slam with C or H be the trump(H is 3-2), but they stopped at 5d and end up with 5d-2. There are something wrong with that 4NT I think.

If the robot confused clubs and diamonds, maybe it had been looking at your hand diagram.

There is a very simple to use hand editor. Click on the editing symbol that looks like a spade with red vertical stripes on each side.
