So You Have A Fit: Make Sure Your Bid Can Communicate These 4 Types of Fit
With 13 cards on each suit, democratically you need to have at least 7 cards to claim “majority” on the suit (4-3, 5-2). But what consider “good fit” will be at least 8 cards fit (4-4, 5-3, 6-2). While of course the more card is the better when declaring a suit contract, remember that , sometimes, having a double suits fit, playing 4-4 fit as trump gives you more trick than even 5-4 or 5-3 fit as the 5-3/5-4 suit can be used for discarding losers (while 4-4 become trump). Then the important question. There are 4 important types of support, does your bidding system covers it ?
