Hi, I'm trying a strong club system and am wondering what are some methods people use after interference. Here are some of the common cases: 1) Natural interference at 1 level 2) Natural interference at 2 level 3) 2 suiter interference, one suit known 4) 2 suiter interference, both suits unknown Playing with my partner strong club, I opened 1C-(1S)-X (showing 6-9 any). Holding Ax,AKxxx,AKxx, Ax what would be your agreements on how to bid? Thanks for any advice on this topic! Gideon
