MATCHPOINT STRATEGY
PART III:  MINOR SUIT GAME, NO TRUMPS OR A MINOR SUIT SLAM
In matchpoint play we rarely play five of a minor suit.  Three no trumps is usually easier and always more rewarding.  Three no-trumps, making four (430 or 630) is worth more than five diamonds, making six (420 or 620).  In our pursuit of three notrump contracts we use various treatments and conventions.
The auction S. 1    N. 2,   S. 3 is very close to forcing.  A rebid of 4 by SOUTH would be invitation to slam in diamonds.
The inverted minor suit raise treatment was created to give a partnership room to find a makeable three notrump contract.  Although the fourth suit artificial and forcing convention is not used exclusively for finding notrump games it does keep the bidding low.  Although the fourth suit artificial and forcing convention is not used exclusively for finding notrump games it does keep the bidding low.
If a parnership is not using inverted minor suit raises the auction 1  pass  3askes the opener to rebid 3NT if he has a suitable hand.

Here is an example of a hand that calls of a raise of a five of a minor to slam: North:  A9 K76 A9754 KQ10
The Bidding:
SOUTH WEST NORTH EAST
1   pass 3
5   pass ?
North passed and 6 was made for a 420 and zero matchpoints.  6 would have been the top score
