I have come across 2 versions of the Modified Wolff Convention:
(a) Responder is showing at least 5 cards in both Majors, a very weak hand (not suitable for game, unless there is a Fit); basically, asking the Opener to Pass or Correct. Example:
1m-1M
2NT-3C (A relay to 3D. Generally showing a weak hand, with 1 exception.)
3D-3OM (OM=Other Major. Responder confirms a weak hand and asks opener to pass or correct.
(b) Responder is making a slam try in the Om (the other minor).
1m-1M
2NT-3C (A relay to 3D.Generally showing a weak hand, with 2 exceptions)
3D-3OM (A Slam Try in the Other minor)
The bidding shown here assumes no interference by Opponents.
It is assumed that the first exception is 1m-1M-2NT-3C-3D-3NT= Slam Try in the Opener's minor.
I would appreciate receiving comments, based on your own experience with the 2 versions of Modified Wolff. In particular, it may be helpfull to focus on some of the following points:
1) Given the 1m-1M-2NT sequence as a START, what is the relative frequency or probability of the Responder holding (i) A 5-5 Weak M hand; vs (ii) A 5M-5Om Strong-ish hand?
2) How often did the partnership forget the "agreement"?
3) Of course, any other comments are most welcome.
Thanks, in advance for your comments.

What is the reference for those Modified Wolff treatment ?

It seems that they cater to relatively low percentage holdings for Responder.

A few examples with my "normal" version for the following sequences in Wolff Relay are:

1m - 1S
2NT - 3C!
3D! - 3H = 5/5, GF

1m - 1H
2NT - 3C!
3D! - 3S = 4/4, GF

and for the 5/4 or 4/5 :
1m - 1M
2NT - 3C!
3D! - 3oM, GF

and the "sign-off" is :
1m - 1M
2NT - 3C!
3D! - 3M (WEAK)

How do you describe all of these in the "modified" that you found ?

The following 3D = natural, GF, 2nd suit:
1m - 1M
2NT - 3D

And Responder showing a Clubs as a 2nd suit, GF is:
1m - 1M
2NT - 3C!
3D! - 3NT! = 4+♣, 10-12 hcp
