Overcalling Opponent's 1NT

I have a new book coming out through Master Point Press in the next few days. Overcalling Opponent's 1NT. The topic generally is overcalling 1NT openings, but I use the theory to also develop applications for other auctions.

The methods arise from my idea of using two-under as one or both majors (or as one or both minors in other auctions). Using these methods, for instance, you can do better (in my opinion) than the Woolsey defense, while fitting into the ACBL General Conventions Chart, a claim that the Woolsey defense cannot meet.

In Woolsey, for instance, you can handle (1) both majors with a probe as to which is better, (2) one-suited major, (3) major-minor, or (4) the double as typically major-minor canape longer in minor. But, the one-suited major is through 2D, which is not GCC compliant.

Using one of my proposed methods, you can have Overcaller handle (1) both majors with Overcaller defining which he prefers, (2) one-suited major without GCC violation, (3) major-minor, or (4) spades with a longer minor, all without violating the GCC and with retention of the double as penalty, if you want. If you then add in an artificial meaning for the double, you can handle much more than the Woolsey defense could handle, again all GCC legal.

If you add in the Multi used in Woolsey and in Multi-Landy (which I also out perform), you can handle (1) both majors, (2) major-minor, (3) major-MINOR canape, and (4) one major, all without giving up the penalty double! Of course, the penalty double could be added onto that to expand options even further.

You also would have other interesting options, like defining immediately which minor you have, defining immediately (at the two-level) whether you have a values overcall or a garbage overcall, and the like.

I hope you enjoy. I have pasted in the Table of Contents to give you a feel for what the book will be about:

Just downloaded your e-book and am excited about trying to use the 2-under strategy in other areas of bidding.

I have been playing Zebulon over opponent's 1NT where you bid 2-under with a 1-suiter (2 steps up) or a two-suiter with both of the next 2 suits (suction made legal!) Thus, with the majors we would bid 2D instead of 2C.

Let me know how you like this. I think you will like some of the GCC-legal options better than Zebulon, even. There is one structure in the book that has a Zebulon-ish treatment, the part about the sloppy Reverse Flannery 2D.
