A non- jump rebid which indicates extra strength (see also jump-shift): 1) In strict sense: rebid of second, higher- ranked suit than the one previously bid, on a higher level, e.g. 1â(tm)¦ â€“ 1â(tm) ; â(tm)¥ is a reverse by opener, and 1â(tm)¥ â€“ 2â(tm)£; 2â(tm)¥ â€“ 2â(tm) is a reverse by responder. 2) ("High reverse"): Rebid on lower-ranked suit on level 3: e.g. 1â(tm) â€“ 2â(tm)¥; 3â(tm)£ is a "high reverse" by opener, and 1â(tm)¥â(tm)¦â(tm)¥ â€“ 3â(tm)£ is a high reverse by responder.
(1) (noun) a non-jump bid in a new suit that bypasses a bid in a lower-ranking suit already bid by the same player. [North one club, South one spade, North two hearts is a reverse (bypasses two clubs). But North one club, South one heart, North one spade is not (no bypass).].(2) (verb) to make a bid described in (1).
Rebidding a higher ranking suit at a higher level than one's previous bid of a lower ranking suit, forcing partner to prefer the first one (if he has to, which is common) at yet a higher level. As a result, this shows extra strength. The bidding sequence: You Partner is a reverse. If one cannot pass or rebid one's first suit at the current level, then bidding a higher-ranking suit need not show extra values. For example, You LHO Partner RHO Pass is not a reverse.
