we are on our way to slam suit agreed,and opp chips in
with a suit bid after my 4n/t hence DOPI

same scenario and opp x something-hence ROPI
missed a grand because p did not play either.

is it part of Sayc or Sayc 2/1???

fyp.

To answer your question, I think that neither is standard in these systems without prior agreements.

[manudude03]

It's a crapshoot online. If a random partner says SAYC in their profile, just assume they know where the S,A,Y and C keys are on the keyboard. I didn't look particularly hard, but the only link I seen covering the issue does say that DOPI/ROPI are on after interference (this was not the ACBL site though). You need to be sure to agree when it stops being DOPI and starts being DOPE (in a very unlikely scenario, if opps bid 6S over blackwood for hearts, it would be rather silly to play DOPI and find you have 2 key cards. I would generally recommend playing DOPI unless the opponents bid at least 5 of our agreed suit.

edit: Just found a SAYC convention card on the ACBL site (SAYC) and it does say Double=0 Pass=1 next step=2, so yes, DOPI is on (and I assume ROPI too)

[blackshoe]

The ACBL SAYC booklet does not mention DOPI/ROPI, or for that matter any defense to interference in a BW auction at all. Also, it specifies simple BW, and does not mention RKC.

Yes, the sample filled out SAYC card does have DOPI listed, but as it's not in the booklet, it's something that must be discussed. And while my understanding of the SAYC "rules" is that including DOPI isn't an option, I don't suppose it should be a problem, unless you're playing in an event where the booklet is specified as governing.

[Mbodell]

There is also an issue that when playing RKC (or much more commonly 1430) that DOPI has two common meanings:

1. Double zero, Pass one, next step two, etc.

2. Double first step (say 1 or 4), pass second step (say 3 or 0), next step 2 w/o Q, etc.

I prefer the second but IME it is about 50/50 playing with pickups in real life.

I always thought DOPI, ROPI and DEPO were so standard that it doesn't require mentioning this agreement before playing with someone. Guess I was wrong...

[mycroft]

I do know somebody whose bridge opinions I really respect who says "DOPI, sure; but no ROPI. Redouble for business."
I don't do it, but he's got a very good point.

[pirate22]

This actually happened my pard passed with 2 aces
so i x 6 spades-and we were cold for 7 hts...
the agreed suit Dopi 100% correct.
I will search the hand out and display it

This is the defense to the Jansma dbl:

dbl: I gamble that you haven't agreed on the meaning of your responses after a dbl
rdbl: you lost

You really need to provide the full auction, if it went ......4NT-(6S) then it would be insane to play DOPI (grand slam off the ace of trumps possible). I guess either partner doesn't know what to do (and is passing to not shut you out) or is playing DOPE (and passed to show an even number). FWIW, I play DOPE when the opponents bid 5 of our suit or higher and DOPI below that.

edit: just looked up hand records, I believe the hand he was on about was

1H-(3D)-4NT-(5S)
P-(P)-6H-(P)
P-(6S)-X-AP

[pirate22]

yes that was the hand 7 was on...
another CHESTNUT--- if partner opens 4n/t

what is he asking??? Ace or Aces ???
if so...
how do you respond if you have Ace CL
" Ace d
Ace H
Ace sp
and ................ 2 Aces

[Zelandakh]

If your partner opens 4NT without discussion then they are not being considerate. That said, the specific ace-asking convention is defined as a part of some systems. For example, in Acol, the responses with the CA would be 6C and with 2 (or more) aces 5NT. It may be (I do not know) that this is different in other systems. It is very common to reverse the meanings of 5NT and 6C, and with a random pick-up I would not be trustful that specific ace-asking was meant at all.

Similarly, on your given hand some play a conventional pass-double here and some are used to simply playing double for penalties. You should not assume to know your partner's agreements without discussion, unless they are claiming to be world class (like you?) anyway.

[pirate22]

World Campion im not--but you answered correctly 100%
6cl with ace clubs and bid 5n/t with 2 aces.
On BBO this comes up quite frequently,and without prior discussion
agree with you..advanced and above i would use it.
