This time, the board of the week is about bidding. András Budinszky and András Talyigás reached the grand slam on this board using 17 bids, which is quite a lot, considering there are only 35 possible bids in the bidding box. Opening with a precision 1♣ East started a relay sequence and he had enough space to learn almost every card West held. First, he discovered the 4-5-3-1 distribution, the 11+ points and the 0 aces (4♦). Later West showed the queen of hearts and the king of spades and denied the king of diamonds. East still wanted to know West’s remaining honors to see if there are 13 easy tricks in 7NT or should they play the safer 7♥. West promised the queen of spades, the jack of hearts and denied the queen of diamonds and the jack of spades so he had to have the king of clubs to have 11 points. Knowing all this, East decided to bid 7♥ and claimed right after drawing the trumps.
Here is another interesting situation, after the seven of diamonds lead, how do you plan to make 3NT, which card would you play from dummy?
