If partner was just shy of accepting the game try, is a cue over game never appropriate?
NEVER
Here are some reasons:
- You have limited your hand and partner has signed off in game. This is really the only reason that matters.
- Like I said, if partner still has slam interest despite your non-accept he could have given you the opportunity to cuebid at a sane level. He chose not to do so, hence he no longer has slam interest (not that he "promised" slam interest to begin with - see below).
- It is very possible that partner never had slam interest to begin with for various reasons:
1) He may have been trying to keep 3NT in the picture
2) He might be looking to play in a different trump suit if you could raise the "game try" (for example, after 1S-2S you can bid 3H with a game-only hand since we might have a 9-card heart fit and an 8-card spade fit)
3) He may have been trying to dissuade an opening lead in his "game try" suit
4) He may have been trying to attract an opening lead in his "game try" suit
(Granted 3 and 4 might be considered Zia-like maneuvers - not important to add these to your playbook)
Responder doesn't need to think about any of these possibilities - he should just respect the fact that opener is the captain and has placed the contract. 4S is just a natural bid - it doesn't "show" anything (except the desire to try to win 10 tricks with spades as trump).
