Mohan on Blackwood
Dr. Mohan, our team’s leading proponent of frequent Blackwood bids, suggests the following team understandings concerning when a bid of the partnership minor is KC Blackwood:
- After an inverted minor, by either partner at the 4 level
- After a minor suit positive by responder to a 2
opener, when opener raises the suit, either immediately or at the next turn to bid - By opener, after a reverse and a constructive raise by responder
It would be nice to achieve a consensus on that to ease memory of the system. Please comment on the suggestions and any logical additions. I’ll post a follow up after we have the group’s opinions recorded.
These suggestions are very sensible one, though I think in the case of inverted minor, only unlimited hand should be allowed to ask for keycards:
1C-2C (limit+);
3C(min, nf)-3S(strong, spade values);
4C?? (imo, RKB interpretation is insane)
Logical additions:
1) After 2/1 FG & minor agreement below 4m, 4m is RKB (you may have to discuss whether the sequence 1M-2m; 4m is RKB; Dr. Rosenkranz suggests it to be, while Eddie Kantar says it is a pic. bid, maintaining that ask should follow firm suit agreement)
2) After you overcall in 2m, and advancer cue-bid to show fit, 4m can be played as RKB if it is a jump (redundant in natural meaning)
I guess the default agreement maybe something like:
1) Unneccessary jump to 4m after minor agreement in constructive auction is RKB
2) After FG is established and minor agreement below 4m is in place, 4m is RKB.

I would like to know if you have agreements on how to answer blackwood with a void playing RKC. Thanks for any suggestions. While I have seen many schemes, I don’t think I’ve found the right one yet.
