Yes, pass is clearly forcing here. My double assumes a pass-double inversion (so it is a moderate suggestion to penalize); if not, I'll pass like Richard.

We play 2NT as an invitational+ 4 card raise in competition. But it seems that this style might be slightly better in allowing minor signoffs.

On the positive side, I have good controls. On the negative side, I am balanced. 3 seems right. I'm sure we will be better placed after this auction, in particular since (looking into the future) partner clearly has spade shortage.

Overcall, because i would like to have full high card strength when doubling at this position. Otherwise the double is just too wide ranging,and partner might overvalue our defense.

In 2/1, SAYC, or any 5 card major system: open the longer minor.

3NT over a non-lebensohl response.

2-2-3 gives more or less the same room, doesn't it?

With 5-6 I can reverse light, so with 6-5 I can open light. 27 Zar points, for that matter.

Sure. You have such a hand 13.2% of the time. I assume you include any 4333 and 4432, too.

“One downside, aside from the obvious degree of risk, is that the 1♦ opening takes on a wider range of balanced hands, compared to some other strong 1♣ systems. ”

Passing 4333 and 4432 10-12 hands is not a crime against nature. :-)

I presume that systemically, 5 card suits must be bid right away, so rejecting a transfer shows exactly 4441 and opener can bid to a good fit. To be honest, to me it seems that it's reasonable to just play in a 5-1 or 6-1 fit in this uncommon situation.

After doing some simple simulations, I have to nuance my judgment. As dealer, I have a “New NT” hand roughly 7.5% of the time. That is, if you also open any 5422 hand 1NT; otherwise it's 4.8% of the time; less than a standard 15-17 NT opening (5.7%).

Meanwhile, with a “more normal” mini notrump opening which opens 1NT 10-12 only on semibalanced hands without a 5 card major (not too awfully uncommon), the opening frequency is 12.4%. An aggressive mini-notrump that opens all semibalanced hands except 5M(422) has an opening frequency of 15.3%.

Altogether, if you include 5422 hands, it seems like this convention might have a good enough frequency to be useful.

If we have an agreement about 2NT (so that we can check whether dummy has an outside entry), that would make sense. Alas, 2NT is clearly natural according to your conditions.

The main advantage of bidding 3NT was clearly to let the better player declare. :-)

Excellent spots, lots of aces and kings. I think it's worth an upgrade.

K&R (AKJT T4 KJ92 AK7) = 20.35

This opening has good preemptive value when it happens, but it doesn't seem like it will happen often enough to be worth allotting the valuable bidding real estate that the 1NT opening is.

That might make sense. But I'm having a hard time coming up with shapes where that would be reasonable on this auction.

East held:
QT xx QT9xx Q9xx (!)

West doubled for the lead on KJT tight.

After we ruff our clubs and successfully finesse hearts (East ruffing in on the last trick), he must return either a spade or a diamond. Either case lets us score a pointed jack.

I don't mind the suggestion, but actually, if I had followed David's line 3 is makable for a top, while the misfit with the poor splits means that no game can be made. 100%. :-)

Stupidly, I cashed a second diamond first, and we got down one. 0%. :-(

4-5 loser hand, easy 4 any vulnerability. Enjoy the five level, opps.
