2¨ = 5+ hearts, 0+ hcp. East uses the
Jacóby transfer because he is a little too weak for a Smolen
Transfer*.
3© = 4+ ©-support,
maximum hand.
More discussion to follow.
*Smolen transfer = gameforcing jump
in 4-card major, too show 5-card suit in the other major, when opener denies 4-card majors
in 1NT-2§-2¨.

Pass = North has little to offer in the
majors, so he does wise to pass quickly.
1© = In Walsh
Approach, East may bypass a 4+ ¨-suit,
so West must alert.

Dbl = An excellent hand for a takeout
double, unlike the North hand of board 10.
Dbl = Repeating the takeout double. North is
not strong enough to bid 2§ here.
Rdb = Balanced hand, 9+ hcp, similar to
1D-dbl-rdb.
2© = 4+ suit, 0+ hcp. Remember, South must
chose, unless he has equal length in the unbid suits.
3© = Ultimate invite, justified by the 14 hcp plus
void in diamonds.
