1. My partner opens 1S. Hearts are only 4-card suit in my 14-point hand. That would satisfy the rubric got 2-over-1, but we are told again and again that a response of 2H promises a 5-card suit. 2. My partner opens 1H. Spades are the only 4-card suit in my 14-point hand. But we are told again and again that responding 2S would amount to a jump-shift, promising a long, good-quality suit, and a hand of at least 16 HCP. Might it be permissible, where there is either of those difficulties, to use the response of 2C as satisfying the rubric for 2-over-1, but saying nothing about responder’s actual longest suit ?
