Off-shape unusual 2/1 Forcing to game. 2/1 in comp. is forcing but can be light Can open 4-card M in 3rd or 4th, but only with minimum and good suit We vary with 4-4 in minors. With 4-5, almost always 1. Respond can very light Always a little more likely to open light with a good suit. May respond with a very weak hand. Almost always bid 1 over 1 with 4-card suit less than GF and <3-card 's. 1M-1N is semiforcing, max. 12HCP Overcalls are wide range - can be pretty light (but always a reason to bid).
