RHO opened 3D, I passed and my partner made a takeoutdouble in fourth position.
With Kxxx Qxxxxx Kx xx I bid 4D asking partner to pick a major but he bid 4NT.
He took my 4D as forcing with an unknown distribution. I never heard of that as
I always used quebidding opponents minor on the fourlevel as pick a major.
Now I just want to know which bidding is most common.

Most good players I know of use 4♦ as pick-a-major.

It is also common to play with 13 cards, not 14

I think it is slightly better that 4♦ shows any 2 places to play, not necessarily both majors.
For example 4♦ is fine with 4225 , planning to bid 4♠ over 4♥ from partner , offering a choice between spades and clubs.

Good idea, but partner must bid on the assumption that it shows majors (you will correct if he bids the wrong one): any minimum double with good enough clubs to insist on them should have overcalled clubs instead. (3♦-X-(P)-4♦-(P)-5♣ should imply good clubs with substantial extra value--too good to overcall. Partner will boost this to six almost any time clubs is one of his two suits--though he might pass if he is very ashamed of his 4♦ bid.

13 cards is optional. Pick a major (with M/m 2-suit correction possible) is not optional...can't imagine any other useful meaning.

IMO you and partner are both right 4♦ is game-forcing, usually with doubt over strain. With 5+ ♥, however, perhaps you should just choose 4♥, yourself.

Nice. Except, my 4D bid can be very bad, and I am not ashamed
