4§ = Midi-Splinter: 4+ ª-support, singleton or void in clubs, and 10-11 hcp. The
requirements can be lowered, since West has passed at his first turn. This narrows the
range of 2NT Garozzo Splinter to hands with 4+ ª-support, some
singleton or void, and 8-9 hcp, for the sake of maximum accuracy.
Discussion to follow.
