comment Should “100 or 150 honors” allow you to open light?
@PieterGeerkens: The point of the question (as revised), is "Do the honors (including 1 T) signal that the holding is stronger than its nominal value? (That is, "10" is really worth 11?) In your other example, you convinced me that your "11 hcp" holding with tens and nines was actually worth 12.

comment If you are fourth seat after a third seat raise, can you make a takeout double with “intermediate” values?
@PieterGeerkens: I did say 12 with 4-4-4-1. The "intermediates" work well with the J's so I would evaluate the hand as 12. Replace the T and two 9s with lower cards and I would NOT double with that hand in second seat because those intermediates are probably on the other side.

comment Are there viable alternatives to a “three level pre-empt” with a good seven card suit?
Yes, vulnerability is an important factor, more, perhaps, than I suspected.

@PieterGeerkens: You mean xxx-xx-x "or better" in the side suits, right? Because you'd be happy with xxx-xxx-0 or xxxx-x-x?

comment Are there viable alternatives to a “three level pre-empt” with a good seven card suit?
If you say don't open AKQxxxx xx xx xx as "two," I'd go to 1S, not 3S.The reason I quarrel with opening AKQxxxx xx xx xx as "three" and KJxxxx xxx xx xx as "two" is because the former is the stronger hand, and yet I'm using the weaker bid. If you're using 6-10 for "weak two," I'd say that AKQxxxx xx xx xx is much stronger than any balanced "10," and I'd open 1S.

comment Are there viable alternatives to a “three level pre-empt” with a good seven card suit?
I was taught that "weak two" was anywhere from 6-12 points. KJxxxx xxx xx xx is "six" (counting distribution and with the side king removed) and AKQxxxx xx xx xx is "12," again counting distribution. So unless I was taught wrong, the "usual" remedies ought to apply. In a forced choice, I would open AKQxxxx xx xx xx 1S rather than 3S. It has seven probable tricks, and should make game opposite an opening hand (three probable tricks), even if we end up with only 21-22 hcps between us.

comment Is“ third seat, favorable vulnerabilty” the only appropriate time to pre-empt with “any seven” of a suit?
Strangely enough, I would rather defend than preempt with your KJTxxxx-xx-KTx. The two reasons are your side honors, and the K-J, K-T tenaces that are hard to overcome. This hand should prevent most slams, but it is vulnerable on offense to "offside" cards. You have 7 hcps (8 counting the T/s), not much below the average of 10. I "like" 1100 point penalties only when I see a slam for the opponents, here I don't.

comment Is“ third seat, favorable vulnerabilty” the only appropriate time to pre-empt with “any seven” of a suit?
Thank you for a long and informative answer. But with a hand like x-KJTxxxx-xx-KTx, my inclination is to open a weak two with it. And save "weak three" for "no defense." Put another way, open 1 with 12-13 points, open 2 with 6-7 (and distribution), open 3 with 0, 1, 2, 3, etc. FWIW, I consider "single face card hands" in the same category as 8765432, which was just an extreme case. Maybe I need to revisit the distribution of weak hands.

@PieterGeerkens: 1) How is partner stacked in other suits if I'm doing this in third position because s/he passed initially? 2) To the extent that partner has tricks on defense, s/he reduces my penalty on offense. I can make up a scenario that s/he has "three queens" for defense that are worthless for offense, but that's rare.

comment If you decide to play for “top or bottom” in duplicate, are you supposed to consult with partner?
@PieterGeerkens: Thanks for your help. I do not expect to make the bad anti-queen plays that you mentioned, because that is irrational even in rubber (my "home") game, but I might end up making safety plays in duplicate because they are rational in rubber. Just not in duplicate. And when I talk about these behaviors, I'm thinking in terms of "one time, on my worst night." I wouldn't do this systematically like Cohen and Katz.

@PieterGeerkens: Then "playing for top or bottom" is like a "psych" situation, where partner can't be in on the secret, right?

So the essence of cheating is making technically inferior plays, and getting superior results, because the Bayesian information set has been illegally altered, right? And if I or Alexander made these "top or bottom" plays without illegal signals, we wouldn't necessarily be considered cheaters, but would run the risk of being tagged as inferior players.

comment In duplicate, is it ethical to base your play on other people's body language?
@AlexanderWoo: So then the ethical thing to do is to inform the tournament director as soon as you realize that you inadvertently have an 'unfair advantage," right?

comment In duplicate, is it ethical to base your play on other people's body language?
@PieterGeerkens: If there was no tangible evidence of cheating, how would you establish that the declarer who made the safety play was or wasn't in a "top or bottom mode" as he was claiming? By his play on other late hands?

If an "onside" opponent at your table hesitated when you were playing a finesse, that would be a permitted inference, right?

comment With which “non-trump” holdings is a 4-4 fit superior to a 5-4 fit?
@PieterGeerkens:Then a 4-4 fit needs an "imbalance" in side suits to shine. Ideally a partnership holding of 8-8-5-5 (or better), rather than 8-6-6-6 (unless the latter were something like 4-2-4-3 opposite 4-4-2-3). That was the point of the question.
