He rebids 1NT to show 12-14 points and let responder bid again. So far this is NOT alerted.\n\nSouth bids the unbid minor--now it is New Minor Forcing. It is artificial and does not show biddable clubs. North alerts this bid.\n\nNorth knows that South has 5 spades, since that is the reason for bidding New Minor Forcing--to tell partner, \"I have 5 of the major I bid; do you have 3?\"\n\nNorth does have 3 spades, but if he also has 4 hearts his first priority is showing them in case there is a 4-4 heart fit with partner.\n\nSouth rebids his spades. This does not show 6 spades--it merely denies 4 hearts.\n\nNorth now has the whole picture and can bid game in spades."}
