I group these suitless positive responses together for simplicity. These
responses deny 4-card majors and 6-card minors. I also list 1♣ -3NT here as
reference because it takes precedence over 1♣ -2NT.

I took the artificial 2♦ relay from FunBridge . I found
it better than most Polish Club literature.
