Last night I was playing 3NT and reached the above position. I led the
♥J towards the A, but West discarded a diamond. Then he found a heart in his hand.
Now I was able to finesse and demand a diamond lead. This resulted in three extra tricks, while if West had simply let the revoke become established, I would have got one extra trick. Should this opportunity for sharp practice really exist?
Note: I could not figure out how to edit the diagram. Please assume that West has one more spade and one fewer heart.
My view is that only 1. the revoker, and, 2. the LHO, ought to have the right to draw attention to a failure to follow. This belief rests mostly upon the principles of one action per turn (acting only at one's turn) the minimizing the creation of UI.
As such, the LHO will always have the opportunity to coerce a revoker to pay the PC penalty
instead of paying the trick penalty. And certainly, revoker can choose the same, and in practice typically does. And, by the same token, an opponent (RHO) ought not be able to illegally coerce revoker to create a PC. This seems to me to be a balancing of the equities
not a flaw.
Now, the true problem is incorporating tripe like
each player must follow suit if possible. This obligation takes precedence over all other requirements of these Laws.
Because when it is made law there is some unsuspecting soul that believes it. Think about it. Just how important is not revoking when a revoke must
not be corrected after it is established?
