[blml] Quick Duck

[Wayne Burrows]

In another forum a poster responded to this question:

"On the diamond lead, (you have Tx of diamonds opposite Kx), what do
you play? MP." - Kx in dummy if that is not clear.

"Quick duck seems clear "

I am not sure exactly what was intended by "Quick duck" but it seems
to me that an "in tempo duck" is ok but a "quick duck" could be
construed as trying to deceive the opponents by varying your tempo.

"A player may not attempt to mislead an opponent by means of remark or
gesture, through the haste or hesitancy of a call or play (as in
hesitating before playing a singleton), or by the manner in which the
call or play is made." L73D2

Could a "quick duck" be a violation here?
