...only questions:
- Game before slam, so it is best to play 3♥ here as another game-try? (so 3♥ is either a game try or Slam interest).
- Responder bids 3♠ with minimum, 4♠ with almost minimum, 3NT non-serious with some extras (in case opener has a slam interest), Cue with slam interest.
- If responder cues over 3♥: f.i. responder bids 4♣, should opener always cooperate, also if 3♥ was a game-try (then responder can only cue with a slam-interest opposite an almost minimum opener) or should opener only cooperate if he has a slam interest himself?
...or if responder cues, opener cooperates and responder bids 4♠ then this shows a 'polite cue' (good hand opposite a slam interest of opener, but only game interest if opener had a game-try).
...but then if responder cues 4♣, opener cues 4♥: what is 4♠ by responder?: does this deny ♦-control or does this show the 'polite cue'?
