[hv=pc=n&n=sj8h953daqt94cakq&d=s&v=b&b=7&a=1sp2dp2hp]133|200[/hv] I play 2/1 with a good partner who is more familiar with 2/1 than myself. Absent discussion is there a standard meaning for a jump to 3NT, does it show extra values? If you bid 2NT and partner raises to 3NT are you bidding again? If not, what should partner be bidding over 2NT holding extras, e.g. AKQxx AKxx xx xx? How do either of you show extra values in the subsequent auction? If 3NT shows this hand including the extra values, then suppose you hold a hand such as Kx Kxx AQ109x Axx which wants to keep other strains in the picture. This hand surely bids 2NT, but the question remains how does either player show extras?
