Defense
The best bridge players are identified by
their defense - - not only bidding and declarer play.
Defense is the most difficult part,
and to many the most interesting,
part of competitive bridge.
Consider that two players,
who can't see each other's hands
and who must not pass illegal information,
compete against a declarer who can see
all 26 of his cards and has
most of the values, too.
That's hard - - and fun.
