I have seen several top players now opening 1c on balanced hands in the 15-19 range and use transfer responses. However, I have struggled to find much online by way of replying to this. I have managed to piece together something that seems to work ok to me and would be happy to email this to anyone else interested. I would also be happy to hear from anyone else that plays, or is thinking of playing, this. It can be used with any other bidding system but my version includes 5 card majors and a 12-14 no trump, multi 2d, Lucas 2s' etc.
