Why responder reverse with Majors 4/4

[paulsim]

Hi all,

 

Bots and more people bid a reverse with 4/4 in the majors playing extended walsh

 

1D.....1H

1NT*...2S?

 

If 1NT doesn`t deny 4S

Why do they bid a reverse with 4S and 4H instead of NMF?

 

Ty all,

Kind Regards

It allows you to distinguish between the 4/4 hands and the hands with four spades and longer hearts. The most common agreement I've seen is that if you are playing some sort of checkback, you can define the auction

 

1m - 1H

1NT - 2S

 

as 4/4 invitational. Both the stronger 4/4 hands and all hands with longer hearts bid something else over 1NT.
