POWERFUL HANDS I63
gate opening bids of 2-No Trumps rather than 2 -Hearts; the suit bid on only four cards possesses
no advantage over the no-trump approach for those
hands lacking guards in the fourth suit; about 4 out
of 5 hands allowing opening bids of 2-Hearts justify an assist by partner on 2 small trumps and a
single definite trick; it would be upsetting in 4 of 5
instances to be obliged to even consider the possibility that partner does not desire you to assist his
opening bid of 2-Hearts upon 3 small trumps and
a sure trick. In view of the above facts giving a
possible double meaning to an opening bid of 2 -Hearts is not in line with efficiency and it cannot be
justified. Never make an opening bid of two on
any 4.card suit.
