West led the ♣ Q
, and GIB could do no better or worse
than the average human, winning in hand.
Short of entries, GIB exited its hand with the ♦ 10
which West won with the queen. East signaled, mysteriously,
with the ♦ 8
. East's signal was going to prove costly under
the eagle eye of GIB.
West continued the ♣ J
, which GIB won in dummy, pitching a
small heart from hand. GIB then took the spade finesse, which
won, and exited with the ♦ K
, pitching a spade from dummy.
East won and led the ♥ J
, GIB covered and West won

. West exited with the ♠ 9

♦ 6-3, giving GIB
If East had ducked the ♦ 10
, GIB was still going to make its
overtrick, by immediately playing the ♠ J-2
East to lead from ♦ J-4
into ♦ 6-3
