East and West are a married couple who play together regularly but are generally weak players. East's 2NT rebid was supposedly 11-12 and West had no answer as to why she did not go on to game.
This took place in a German club but I am interested in procedures for other regions and for other circumstances too (I know the EBU have a special way of handling these sorts of things for example). What would you do if:
a. the hand was played behind screens;
b. the hand was played without screens and E-W are known for giving a great deal of body language signals; but nothing specific on this hand can be pointed to;
c. as per b but a similar incident occurred later in the same session;
d. East made an obvious gesture during the hand and N-S believe this to be a signal for a weak hand
Would you only consider an adjustment if N-S were damaged in the play of 2NT (thinking West was weaker)? In reality, N-S were not damaged in their defence of 2NT (East butchered the play to go one down) and did not call the TD. The actual scenario was either b or c (I think c but my German was not good enough to understand the other incident fully) but I have asked the question more generally since I think that is more interesting. I also think it quite likely that a variation of scenario d will be faced sometime soon.
