What happens if S passes first round?

Both sides make a small slam! Only one NS got to 4♥, when S bid 1♥ over 1♣ Other tables played 1♦ North's pass is strange. GIB bids often in these situations with a balanced crap. Why it is passing now with a huge hand? Edit: W,N,E is GIB

I play only free robot tournaments with downloaded mobile version 3.91 and Android tablet It freezees now and then, about once in 20 tournaments. This has been going on for a few months. To continue, the application has to be closed and started again.

This deal is from the book Adventures in Card Play by Ottlik & Kelsey

Still only 11 tricks without club finesse: 7 spades, 1 heart, 2 diamonds, 1 club, but if East is 4-4-2-3 with club king it is 12 tricks.

I made a simulation of 100 deals with Deal3.1 hand generator.I gave west 5 spades, 4-5 hearts and 11-16 hcp, east 0-2 spades, 3-4 hearts and 6-9 hcp, north 5 hearts. Doubling or bidding 2NT by South is a clear winner. Bidding 3 clubs/diamonds ( or 5c/d a couple of times ) after 2NT wins on average 1.2 imps/board. There were over twenty double partscore swings and about the same amount two imp wins ( +110 vs. +50 ) Doubling might be better, but it will backfire a few times in practice.

This looks normal 1♠ opening.

3NT is explained as 13-15 hcp, 3 spades and 3343, any 4 card suit.

Yes, I knew we might make 7♠ or fail in 6♠. I just bid 6♠ to make it more difficult for GIB to cash the diamonds if we are missing AK of ♦
