Overcalls after a 1NT opening: the minor/major double

The minor/major double
This is the most frequent two-suited overcall after a 1NT opening. (There are 4 possible combinations...against only one for the Landy!) It promises:

A minor of at least 5 cards, a four-card major,
at least 10 or so HCP and, above all, the high cards concentrated in the long suits.

Remember, to overcall after a 1NT opening, distribution is more important than the number of points.

If he wishes to know the 4 card major, he bids 2 diamonds.
With a strong hand your Partner can pass and turn the double into a penalty double!

The bidding after the doubler's Partner has replied 2 clubs or 2 diamonds

After your bid of 2 diamonds, pass if the major called by the doubler suits you. If not, bid 2NT to find refuge in the minors (not to play 2NT of course!)
After your bid of 2 clubs, pass after your Partner bids his minor.

S	W	N	E

Pass Your Partner has bid 2 diamonds in reply to your 2 club bid which asked him for his long minor. You are going to play this contract relaxed!
