 Thus, opener's reverse must show values at least one trick beyond the minimum needed to open.For example, following 1 – 1 ; 2 – ?, responder may have a weak hand such as QJ86 K2 8762 Q74 and be planning to rebid 2, a simple preference, if opener made a typical rebid such as 1NT or 2, and to pass if opener rebid 2 or 2.However, following the reverse, he must now rebid 3.
