Yes, the Encyclopedia quote discussed discards.

And yes, Roman Odd-Even:
- is used when following suit
- has even cards conveying suit-preference

This has been confirmed on this page by quotes from Sheinwold and Wolff.

Roman Odd-Even when following suit was what Barry's original question was about… not a different method (no suit-preference) during a different part of the game (discarding).

We are in agreement - genuine Roman Odd-Even signals, as described by Avarelli and Belladonna in their 1959 and 1969 system books (odd = encouraging, even = discouraging and suit-preferance), are unplayable.

Sheinwold also agreed; that is why he wrote (quoted above):

I have never seen odd-even signals used without hesitations and emotions. If you play a card slowly and reluctantly, partner will understand that perhaps you didn’t have a card of the right kind, and he will make allowance for your “misleading” signal. If you play a card quickly and casually, partner will understand that you have no problem, and he will accept the signal at its face value.

Bobby Wolff discusses the Aces - Sharif Bridge Circus matches of 1971:


It was during the mid-week Open Pairs events, when I (and the other Aces) would play with members of the Circus as our partners, that something began to distress me. My partner (regardless of who it was) almost always suggested that we play a particular carding method which he was accustomed to using — and I, too, soon fell in love with it. It is known as odd-even signals and it can be used when following suit or discarding. Using this method, a “discouraging” even spotcard (like a two or an eight) also had suit preference overtones, allowing the tempo (obviously not discussed) to suggest just how much partner wanted that suit. Thus, playing an odd card would be “encouraging” — but only an even card could have a dual meaning.

Michael:

Barry's post says:

They were playing odd-even signals, at least on opening lead.

Roman Club was the first system to use odd-even signals when following suit to partner's lead.

Roman Club System, Avarelli and Belladonna:

When partner leads from an honor sequence, an odd card encourages continuation. If no odd card is held, a high even card fulfills the same function.

We agree that standard signals are:
high = like
low = don't like.

This is binary.

We don't agree that Odd-Even just a “new ordering of cards.”

Odd-Even is not binary because of the injection of suit-preference into the even cards, as I outlined above.

This leads to “issues”, as Sheinwold describes, above,

Certainly agree against decent opponents… the chance of playing the hand is low, and backing-in just feeds declarer useful information,

Bill:

From the Encyclopedia of Bridge, 7th ed:

ODD-EVEN DISCARDS.
A signaling method that assigns different meanings to odd- and even-numbered spot cards. The discard of an odd-numbered card (3, 5, etc.) encourages in that suit. The discard of an even-numbered card (2, 4, etc.) discourages and often doubles as a suit-preference signal.

I do not agree with these recent comments. More specifically, I do not agree with Steve Bloom, below:

Suppose you are playing a (right-side up) 3-way signalling system.

Let's suppose not… ie, one plays, as I do, reverse attitude on partner's lead.

Say spades are trumps and partner leads CA.
- my low club says I do not prefer a shift to a red suit
- my high club says I prefer a shift to a red suit.

The card is, with rare exceptions, mono-meaning.

I do not agree with the comments that maintain that Odd-Even is just a reordering of the cards.

I requote Sheinwold, above:

What if you don’t have an odd card to encourage a continuation? Then some very high even card will have to do the job. Partner will understand.

What if you have only odd cards, but want to discourage a continuation? Or what if you have only a low even card but want to encourage a shift to a high suit? Partner will understand.


With Odd-Even:
- an odd card is encouraging or (not, from only odd cards)
- an high even card is high suit-preference or (not, from only odd cards) or (not, with only one even card)
- a low even card is low suit-preference or (not, from only odd cards) or (not, with only one low card)

The card is multi-meaning.

I'm not following these objections.

We are West and we are assigned three passes. I believe we are asked, “Of how many of these passes do we approve?”

So what did North have, to leave in a takeout double?

Sometimes playing UDCA you don't have a small card.[

Well, if one does not have a singleton, one always has a lower/lowest card. Odd-even is intrinsically-different; an even card can have one of two meanings: suit-preference, or encouraging when holding only even cards or an odd card one cannot afford.

Alfred Sheinwold:

What if you don’t have an odd card to encourage a continuation? Then some very high even card will have to do the job. Partner will understand.

What if you have only odd cards, but want to discourage a continuation? Or what if you have only a low even card but want to encourage a shift to a high suit? Partner will understand.

I have never seen odd-even signals used without hesitations and emotions. If you play a card slowly and reluctantly, partner will understand that perhaps you didn’t have a card of the right kind, and he will make allowance for your “misleading” signal.

Foreword by Mike Lawrence, Under the Table, page v:

Garozzo led the king of clubs. Here’s the layout of the club suit that I could see.


♣J4
♣K ♣ A10862

I liked the lead. I wanted to play an odd card to show interest. I wanted to win the second club which would leave us better placed with me on lead. I looked for an odd card to signal with but I didn’t have one.

I had read that when you don’t have an odd card, you are supposed to play your highest even card to encourage. So I played the ten. I had been told that partner would understand what my intentions were. Partner didn’t. Garozzo switched.

After the hand, Garozzo was very annoyed with me. He wanted to know why I had played the ten. I said I didn’t have an odd one to play. He grabbed my cards out of the box and discovered that I didn’t have any odd clubs. He was still angry as he replaced them in the board. I have always wondered if he was angry that I didn’t have an odd club or whether he was angry with me that I hadn’t played my ten of clubs in a more thoughtful way. Seemed weird. Too early in my relationship with the Blue Team to give it serious thought.

My favourite Test commentator's comment:

“So it's lunch on the third day and the players are heading off the field, with so-and-so stranded on 99. I'm sure he'll be looking to turn that into a big hundred when play resumes. So-and-so's figures: 23 overs, 1 maiden, 1 for 99.”

If you are American, don't ask for an explanation… I don't have several hours to explain what it means and several more hours trying to explain why it's funny.

Thanks for the correction.

My recollection is from reading Forquet & Garozzo's book about 45 years ago, and some time I will double-check the accuracy of my memory…

Mike:
Blue Club did not use Roman Blackwood, although your teammates may have chosen to adopt it. In Blue Club, 4NT was plain Blackwood if used on the first or second round, or as a jump.

But who needs any form of Blackwood at all?

Yes, this is the hand where the ♥K is the right switch. I didn't find it at the table.

Tim Seres used to say:
There is no point in telling your partner, “We would have beaten it if you had (done so-and-so) if there was no sensible way for him to work that out.”

A trump lead is plain silly… misapplying a slogan.

Good hand… I think the low club is certainly findable at single-dummy.
