3♣︎TRF ♦︎, (4)5+♦︎4♠︎, INV+
3♦︎INV+ raise of ♥︎ or ST without a splinter; 3NT cannot be played, so a later 3NT is a nice minimum.
3♥︎4-card ♥︎, exactly an invitation; 3NT can be played
3♠︎+splinters
2NTNT-oriented hand, does not accept the invitation
3♣︎Does not accept the invitation, prefers to play in ♣︎ rather than NT
3♦︎By the general principle below – I accept the invitation with a maximum in ♣︎; afterwards, up to 3NT it is always "stopper / no stopper", and if we continue they were cue-bids.
3♥︎Again by the general principle, I accept the invitation in ♠︎. NB! Here we cannot have four spades, i.e. accepting in ♠︎ is with 3 cards and a suit-oriented hand with 5 hearts. Strange as it may sound, such hands do exist, not to mention hands that may have decided to hide the 4-card spade suit because their opening hand is ragged, and so on.
3♠︎I do not accept the invitation in ♠︎, and I also have a fifth heart
In such positions we apply the general principle that when we have shown two suits, the first step that is not a return to the suit is "I accept in the lower suit", the other is "I accept in the higher". An example of such a hand is AJx Axxxx xx KQx; logically, when partner is 54 in ♠︎ and ♣︎, diamonds are most likely wide open, but he can evaluate that himself too.
