It is with some dismay that I read Georgi's response in that thread, which stated that the rebid would not be made game forcing, but the requirements would be adjusted to reduce the frequency with which it would be passed.
If you are going to go to the trouble of making any adjustment at all, why on earth not simply impose a rule that it is Game forcing? Full stop. End of chat.
Be that as it may, and mindful of the aforementioned thread, along comes this hand:
Paranoid that (uncontested) 2♣-2♦-3♠ is non-forcing at present (AND WILL REMAIN NON-FORCING IN V.29!!) I rebid 4♠
No doubt this is also non-forcing, but at least it is game.
Spotlight on North
North has heard partner open 2♣ and is already essentially worth a slam force on general values.
He hears his partner rebid, not 2♠, not 3♠ but 4♠. 4♠ is presumably a stronger bid than 3♠ if 3♠ is non-forcing.
And still has no grand slam aspiration? Or perhaps I am supposed to punt 7?
