You open 1NT and the bidding goes:
1NT-(P)-P-(2S)
P-(P)-3C-(3S)
?
Your partner could have bid 2S transfer to C initially. After his 3C bid you expect that he prefered to play 1NT above 3C (MP's) and that he has values just below a limit bid (being red): 5 or 6 card Club and about 6 or 7 pts.
Opps are intermediate/advanced.
How many points on 10 do you give for a 4C bid? ... what if vulnerabilty would have been green?
