Inverted Minor Raises

 

 

DEFINITION: - A deviation from standard bidding practices for showing support for an opening bid of one of either Minor suit, Clubs or Diamonds.

 

A single raise is strong and forcing (10 or more HCPs) (Example 1), while a double raise is weak and obstructive (Example 2). This combination of a reversal of bids from standard bidding allows more room for investigation with good hands while, concurrently, offering a preemptive effect with weak hands.

 

When using Inverted Minors, if the opponents intervene over the opening bid, it is a matter of partnership understanding whether or not the use of this inversion is still in effect.

 

Inverted Minor bids are alertable.

 

 

Example 1: You, South, hold:

North South AXX (A bid of 2C shows support

1C P 2C KX with invitational or

XXX greater strength)

KJXXX

 

---------------------------------------

Example 2: You, South, hold:

North South KXX (A bid of 3C is preemptive)

1C P 3C XX

XX

JXXXXX

 

--------------------------------------

 

VARIATION: - Many tournament players modify the above system in order to cover three types of support (forcing, invitational, and preemptive) for a Minor suit opening. In this variation, a jump bid in the Minor is, as above, preemptive; but a jump shift into the other Minor suit (Examples 1 & 2) is invitational showing 11-12 HCPs, and a simple raise to the 2-level in the original Minor (Example 3) is evidencing 13 or more HCPs and is game-forcing.
