2NT = Balanced hand, 20-21 hcp. East should not downgrade for
his 4333-pattern, for he must guard his ace-queen tenaces in spades and diamonds.
3© = Jacóby
transfer: 5+ ©-suit, 0+
hcp.
East has an easy play for 12 tricks, with ¨K on
side.

2¨ = 4+ suit, 10-11 hcp. East has passed
before, so our treatment of "2 over 1 forces
game" is off.
2NT = 5ª332, 12-13 hcp. West should jump to 3NT
with 14 hcp.
Train stops right in time. Clubs break 4-3 as expected (62.17%). ª are well-stopped, so North has lots of time to knock out ©A for his ninth trick.

West has no suit to offer after 1§, North is
completely busted, and East has no reason to balance, so South gets stuck in a 3-1 fit.
That's the price one has to pay on occasion.
If EW defend well, they can set South by 3 tricks, for example: ©A, ©K, §Q for king and ace, ª for queen, ªK, ªA ruffed by East, §7
for ten and jack, §9, © to jack and queen, ©T
ruffed, and ¨A becomes South's last trick.

2§ = One of many types of strong hands.
2¨ = Semi-automatic
relay. Positive responses
of 2©, 2ª,
3§, and 3¨
require a good 5+ suit (KQxxx,
AJTxxx, or better), and 8+
hcp. We would only respond 2NT
on balanced hands with kings or better in all suits.
3NT = Balanced hand (no 5332), and
24-25 hcp.
4§ = 'Ordinary' Stayman.
4© = 4-card ©-suit,
perhaps also 4-card ª-suit.
East corrects to 4©, if North denies possession
of 4-card majors with 4¨.
North leads a § to king and ace. West has 11
tricks when trumps break even. The ¨-finesse
offers a solid 50% chance for the 12 tricks. If ¨J
holds, West has 2 §-pitches on the top
diamonds. If North wins ¨Q, he can only cash
one §-trick, for in that case, West will dump 2
spades on ¨AK.
