Competing at the 1-level

Polish Club 2020 already incorporates Transfer Walsh at the 1-level. One obvious advantage is that we get a “support double” by completing the transfer even without intervention. I generalize it to all non-jump responses to end the debate between standard and negative free bids.

  • 1 or (1)X: transfer, 4+
  • 1 or (1)X: transfer, 4+
  • 1: transfer to 1NT, partly ask for stopper
  • 2: transfer, 5+
  • 2: transfer, 5+

We somehow ignore the meaning of overcalls to deal with artificial and psychic bids. If we need to keep the bidding open, the nebulous 1 gets the job done.

Over (X)

Natural notrump is not very useful after a double, so let’s also use it for transfers. Then 1 takes care of diamonds, the only suit left over.
