3TRF , (4)5+4+, INV+
35+ cards, INV+ on or ST without a self-splinter; then 3NT = accepts without a fit or with some nice 4333, and a cue-bid = accepts with a fit
30544; then 3 = fit, 3NT = stopper, and 4m = fit for that minor

2NTDeclines the invitation
3Declines the invitation, would rather play 3
3Accepts the invitation, fit
3Declines the invitation, fit
3Accepts the invitation, fit
In such positions we apply the general principle that when we have shown two suits, the first step that is not a return to one of the suits is an acceptance on the lower suit, and the other is an acceptance on the higher suit.

In such positions we apply the general principle that when we have shown two suits, the first step that is not a return to one of the suits is an acceptance on the lower suit, and the other is an acceptance on the higher suit. The same development applies over 3 (55MM): there 3M = declines the invitation, 3NT = accepts the invitation and will play in NT, and 4M = / fit respectively.
