General Bidding Style

5 card Majors, SNT (15-17). 5-card M common. Off-shape unusual 2/1 Forcing to game. 2/1 in comp. is forcing but can be light Vulnerable, we pass some balanced hands with 12 HCP and slightly unbalanced hands with 10 or 11 HCP. Third seat can be pretty 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 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). Weak 2M is sound - never 5-card in 1st and 2nd - can be wild shape. No specific requirements. Multi is inferior weak 2. 3-level preempts vary with vul and position, but very rarely a joke except 1st seat fav. Almost all low-level doubles not penalty. Action double.
