Bidding practice

Coaching on

The most widely-played natural bidding system in North America. 5-card majors, strong 1NT (15-17), strong 2C, weak twos, Stayman, and Jacoby transfers.

South is the dealer. No one has bid yet. What is South’s opening call?

Planning

The 5 key cards in RKCB are the 4 aces and the K of trumps. We will use 30/41 as our guide.
It is essential that you and your partner are in agreement and understand whether you are using RKC or just normal Blackwood.
5 clubs will mean 0 or 3 key cards, 5 diamonds will be for 1 or 4 and 5 hearts will be for 3 or 5.
In addition we introduce the Jacoby 2NT convention in reply to 1 hear or spade.
In reply to 1 of a major, 2NT shows 4 card support and an opening hand.

Coaching mode

With 16 HCP and 5 very good spades, bid 1S rather than 1NT
