Only the robots failed to bid this one to at least level of six.

I'm interested in how everyone thinks this should be bid. But to help me I ran it through QPlus 2/1 and slam was reached with a spade double jump I think (4S) bid rather than a cue. Is that not available in GiB 2/1. Isnt a cue too weak for that hand?

I would expect an advanced pair to bid something like:

1♣ (1♥) X (p)
1♠ (p) 5♥ (p)
6♣ (p) 7♠ (p)
p (p)

Not sure if GIB understands Exclusion.

Thx, it does appear to be seriously underbid

Although 5S was rather pessimistic by North, South bears the brunt of the responsibility. North is almost certainly void in hearts so both of those aces are working. 4S was a gross underbid. 5H or even 4N make more sense. Once South survived bidding 4S, 6D over 5S might still get you to the grand slam here.
