In the above auction, no stop card is played when LHO bids 2 diamonds. Partner hesitates briefly, asks about the alert, and then hesitates again for about 10-12 seconds.
I thought this particular hand was going to balance whether or not there was a break-in-tempo, as pass is not really a LA here, but I still have a question about this situation:
Partner is allowed 10 seconds to think after a skip bid whether or not a stop card is played, right? Does that take place immediately after the bid is placed on the table, in which case there would probably be a break in tempo for this hand, or after partner receives an explanation for the alert, in which case there would not be a break in tempo for this hand?
