Yes, he has, no matter what words were used. Else, it would be too easy to 
get round the European law.

This is not the same matter as, say, to check whether a player has 'an 
obvious bid' after UI, which would give away more UI ; here, the knowledge 
that somebody revoked (or didn't) is AI. Therefore, the TD is fully 
entitled to look at the player's hands and react appropriately.

He isn't entitled to know whether LHO has a void in the suit or not, before 
playing from his hand ; in rare cases, this could constitute an 'Alcatraz 
coup' (the knowledge that West has or hasn't a card in the suit is 
essentinal), but this doesn't seem to be the case here (too many clubs 
outstanding to make West's holding in the suit critical). It could be 
different if, say, East had doubled the Stayman enquiry, and the 
probability that West held a void was substantial.

>4. How is West's revoke dealt with?

Is is established. The fact that South played a spade doesn't diminish 
West's responsibility for looking at the cards. Unless some mannerism addes 
to confusion, e.g. South plays a spade and says "I'm following low".
BTW, it's quite plausible that South pulled the wrong card (i.e. he knew 
perfectly well he had some clubs in hand); How would this small error 
(which can be negated by dummy's enquiry - or East's !) allow West's revoke 
to be cancelled ?

Best regards,

    Alain.
