Did he ever make mistakes. It would seem easy to have errors of omission.
Anyway it seems very impressive!

How did the authors discover the problems and the solutions?

Why didn’t South lead the Q? Was he trying to avoid a cover?

I think part of the question of whether to open 1D is how happy or unhappy you are if it goes all pass and I suppose how likely it is? The good news is you are a strong favorite to make it.

Would you change your mind if the stiff ace was in a major?

What improvement would be needed to upgrade the hand for a minimum 3D bid

I could be wrong but, I think there are still rebid problems opening 1D after most responses.

I think that makes sense.

Partner bids 1S would you reverse in hearts or rebid 3NT?

Yeah I realized later my thinking on the bit of East having one small heart and one club was muddled, That calculation of 2/3% applies to drawing one trump and then playing two hearts. I still need to add a little to my calculation of your line since if West has QJxxx and xxx and the diamond queen you would still make. I think that adds maybe 1/6%.

BTW I was trying adhere to your line I just got confused as to that one aspect. Hopefully the rest of my calculations aren’t inaccurate.

I just added a third club to the above.

I think Michael’s line basically loses when trumps are not 2-2 and West has either QJxxx, QJxx and no squeeze or drop,QJx and no drop. I believe those numbers are (0.6x7.5x2/3)+(0.6x24x6/15x1/2x0.95)+(0.6x0.35x1/5x0.90)=3+2.8+3.7=approximately 9.5 subtract another 2/3% if the West hand has a small heart and a singleton club [5%x(7/18x6/17)=roughly 2/3% the 5 being the chance of a small stiff in hearts and the other two the probability if the first two trumps are split 1-1 then the chance that West gets the next two.

The final tally is roughly 91% if my thinking is correct.

I guess I thought bidding two suits with 4-3-3-3 shape was misleading. This way I thought I described my hand better. Also in the event partner does have Qx in spades, the event you’re probably fearing will you be able to get partner to declare it? Meanwhile should partner have a stiff diamond NT plays better from my side though it usually will just be an IMP or two..

Finally with your example hand won’t partner bid 3D after both sequences.

At any rate that was my “reasoning” behind my bid.

Most lines worked. The East hand was KJxx, QJxx, T9, Txx
I was just curious as to what people thought was best and what they made of the negative inferences from the opponents failure to bid.

No. What would you have bid?

The last line should read a high heart.

If partner is 4=3=3=3 and weak does he rebid a three card suit?
