Release of Version 1.2.1
This version has simplified the Bust Responses for all Opening bids as 0-9 HCPs. There are still some exceptions.
Over 1♣, with 0-6 HCPs you must bid the Bust Response (1D), but with 7-9 HCPs and a 5-card Major, you can show your Major at the 1-level.
Over 1♦, with 0-6 HCPs you must bid the Bust Response (1♥), but with 7-9 HCPs and some Distribution Points (hopefully with shortage in Minors), you can bid 2♣.
Over 1♥, with 0-6 HCPs you must bid the Bust Response (1♠), but with 7-9 HCPs and a 4-card Major, you can bid 2♣.
Over 1♠, 1NT now shows 0-9 HCPs (expanded from 0-6 HCPs), and 2♣ now shows 10-12 HCPs (reduced from 7-12 HCPs).
Over a Bust Response, opener with 16+ HCPs is now allowed initiate the Ace/King Ask (previously set at 16+ HCPs after 1♣, and 19+ HCPs after 1♦ and 1♥). This means the Ace/King Ask and replies to Ace/King Ask are consistent.
