Do you play ROPI here or systems on, what is "expert standard"?

[mike777]

I play over x=ignore.

over suit bid:
x=0-3
pass=1-4
next=2 w/o q
next2=2 wQ.

I don't know what standard is but I'd play ROPI-RKC over your 4H! kickback and DBL:
RDBL = 0/3
pass = 1/4
4S! = 2 - ♣Q
4NT! = 2 + ♣Q

RIPO / DIPO - just like regular RKC

Jilly, I think you've exhausted your quota of RKC questions this year.

How about an interesting play or defense problem you've had?

[aguahombre]

If they double our RKC in a minor-suit slam auction, we could have some fun (Minorwood). But, since the double takes up no room over Kickback and we have lots of room available, perhaps using the double to better advantage might be in order.

Thinking of pass without a heart control and simply answering KB if we have first or second round control. Partner can redouble to continue the RKC sequence demanding an answer.

haha

Our defense is usually spot on and my partner is a brilliant declarer and can tell me where I went wrong in the play so those hands don't make it here but I will look out for some interesting ones.

The most logically consistent ordering is the way to preserve the most bidding space.

That means:

1st step is pass
2nd step is XX
3rd step is 4♠
4th step is 4nt

In a typical key card auction you have 4 normal steps (not counting void showing responses) so the steps get labeled the same way. For a 1430 auction:

1st step is 1 or 4
2nd step is 3 or 0
3rd step is 2 w/o Q
4th step is 2 w/ Q

(this fits the ROPI mnemonic if you play 1430)

If you had, say, 1 and the Q and the K of spades then the auction might go pass by you, XX by partner (the cheapest step is a Q ask when you didn't give a Q answer), 4♠ by you showing the spade K.

I'd say that (expert) standard is pass without heart control, redouble with first-round control and another cuebid with control in both suits.

Edit: I see now I misunderstood... ROPI makes sense.

[fromageGB]

Depends on your ace responses ; RKCB ones don't help. Using the simpler 1234 method we find it very easy and nothing to remember. We ignore X, and if they bid a suit, we have X = "I would have bid that", a bid means more aces than that, and a pass is fewer than that. Seems to work. It gives us a choice of game or penalty when the slam is missing.

I have no idea what is expert standard. FWIW, I like:
pass denies a control (1st or 2nd) in the bid suit. Partner can then XX to force Key Card answers. XX is 0-3 with the trump queen, 1st step is 0-3 sans queen and higher bids are normal.
