In this sequence GIB seems to completely misunderstand its own bidding sequence after Michaels. In particular artificial jump overcall of openers suit.

4S by GIB East cannot be to play given that opponents hold at least eight spades. And indeed the bidding explanation just says 11- points. It is clearly intended to prevent South bidding 4S. It looks a decent bid to me. However it must be forcing - GIB West canít pass this bid, which, however, it does, coming off for 4S-7.

GIB west should bid its minor.

I would say one of a kind bidding by GIB, but I wouldn't be telling the truth B-)

I had this exact same sequence too so I checked with advanced robots. Basic robots passed the cue, but the advanced robot got it right: http://tinyurl.com/y32m6mqx

Try doubling with the South hand. Both East and West pass and declarer plays in a 0-4 fit!!
