explained in John Blubaugh's article in the May 1995 ACBL Bulletin the Smolen
convention was devised by the late Mike Smolen of Los Angeles to allow the
notrump bidder to become declarer when responder uses Stayman with 54 or 64
distribution in the majors.
partner opens 1N, you bid Stayman, and partner then responds 2D (no four card
major) these subsequent bids have the following meaning, and both are game
forcing. You jump in the 4 card major to show 5 in the other.
invitational with 5 spades, 4 hearts
2S invitational with 4 spades, 5 hearts
3H Five spades and four hearts
3S Five hearts and four spades
your jump, partner can bid 3NT to deny three-card support for your long suit,
then if you have 6-4 distribution you can retransfer, just as in Advanced
keeps the strong hand concealed, unless, of course, you are using 8-10 HCP one
