RKCB Variations


the hog

Recommended Posts

Early this week, pd and I bid the following to 6C.

 

AQTxx

Kxx

x

K9xx

 

K

Axx

AKQx

A8xxx

 

This was MP and 6N stole the bickies. The problem was that I was unable to read a 3H bid by pd as showing the K or a singleton. I was trying to figure out some method for distiguishing the difference, when I came across the following RKCB variant as played by some Polish pairs.

 

My questions are:

 

Has anyone here played this?

Even if you haven't, can anyone see obvious advs/disadvs with this method?

 

Step responses

 

0-3 KC

1-4 KC

2 KC + 0-3 Kings

2 KC + 1-4 Kings

2 KC + 2 Kings

 

After these the next step asks for the trump Q

First a remark: if you play RKC, you don't have 4 kings left, only 3. So it should be something like:

0/3

1/4

2/5 + 0/3 kings

2/5 + 1 king

2/5 + 2 kings

 

This actually seems like a version of roman blackwood (that I play when no trump is set), but with keycards in stead of aces... The difference is that showing kings with roman blackwood is 40/1/23 and there are 4 kings.

 

This RKCB is nice, but I guess it's purpose isn't usefull enough for every slam ambition in a suit. Imo the normal RKCB is better.

Actually this makes a lot of sense, but as Free points out, there are only 3 Kings left. New thought!! What if you counted the trump Q as a king. Now there would be four kings left and you would no longer need the trump Q ask. Just a thought

Hi Ron!

Try to play 4NT as even KC, skip it with odd KC. This is best way in my opinion, same in competition. Remaining bids below 5 of trump are used for establising Q trump or grand. Example:

 

AQJ10xxxx Kx

xxx Ax

x QJxx

x AKQxx

 

4SP 5CL(1)

5DI(2) 5HE(3)

6SP(4)

 

 

1. cue, odd KC, here 3 ofcourse

2. cue, KC enough for slam

3. No Q trump or cue for grand

4. Q trump, KC not enough for grand
