Schmittberg is a game-forcing major suit raise, similar to the Jacoby
2NT and Stenberg conventions. It was devised by Thomas Schmitt (after whom we
named the convention) in 2005 after we found the (Stenberg-like) scheme we were
playing before to be rather clumsy - we either got to know opener's strength,
or shortnesses, but not both, and in the most frequent "minimum" rebid case,
the opponents got to know opener's hand even if we signed off in game.
Schmittberg allows all of that - all minimum hands have a single rebid, and
responder gets to know strength and any singleton/void when interested.
DescriptionAfter 1M (in a 5M system), 2NT shows 4+ (sometimes 3 good) card support and forces to game in that major. Opener's hand is in one of 3 strength ranges:
After the 3♣ and 3♦ rebids, responder may also choose to describe his hand instead of asking opener, again using the same bids as above. Later on, all bids are cuebids, 4NT is RKC Blackwood.
Mnemonics: The 3oM/3NT rebids fit well in our system, we play 1M-3oM as "any void" splinter and 1M-3NT as "oM single" splinter. 4♣/4♦ are easy to remember as well. The rebids after 3♦-3♥ are shuffled around because of lacking space - it is not hard though to recall the meaning at the table if you remember the continuations after 3♣.
