Hand Evaluation – Systemic ( Wollfe
Relay )
PITBULLS:
A relay is a hand
evaluation concept .
It is analogous to an electrical switch where you can use a relay to stop
current flowing or allow current to flow. In Bridge , a relay allows two sets of
meanings for Bridge bids depending whether the switch was turned on. Lebensohl
is the most common relay in Bridge but there are others. Bridge conventions are
built on hand evaluation concepts.
All expert players realize they
need some sort of structure after a 2NT rebid. NMF or Checkback
Stayman ,
Transfers or Wollfe relay are the popular choices. The choice of my partners
& myself is the Wollfe
relay invented by Bobby Wollfe. The Wollfe relay has the same check back advantages of the
other methods but has one big advantage. This advantage is the ability to escape out of 2NT to a partial . The
Wollfe relay is essentially Lebensohl
just like most relays.
Quite
often we cheat on our responses
especially when partner opens a minor & we have a 5 card
or longer major. This is because we do not want to have 1♣/♦ passed out down 3 vul when we can make a major partial or worse a major game.
Playing the Gandolfo intermediate jump shifts , the Wolffe relay should be mandatory.
Tom bids a major at the one level with a weak jump shift hand.
Partner now bids 2NT so you bid the 3♣ relay and over 3♦ you bid your major
& partner has the option
to pass. I did not say partner must
pass but if her hand is not superb for the major , she
should pass.
Wollfe relay uses the “puppet Stayman” way of finding 4-4 major fits. Instead of
responder asking the 2NT bidder if
she has a 4 card major via normal Stayman , responder tells the opener
that she is 4-4 in the majors.
This is done via the relay as
opener must puppet to 3♦ after the 3♣
bid. Partner after responding a heart & the relay ,
now bids her 4 card spade suit & we have used a different “Stayman”
concept. The relay allows natural
bidding to be strong which to me is the main advantage of the Wollfe
relay. This sequence is forcing to game
despite using 3♣ initially.
The main selling point of
the Wolffe relay is using the relay as a slam try in partners minor. Instead of bidding 3NT directly, you relay
first & then bid 3NT . This shows a balanced
slam try in partner’s minor. Excellent , a slam try below or
at 3NT ! Finding a 5-3
major fit is not done
the NMF way. You do not use the relay
to find a major fit as the hand can be passed out at the 3 level. You find your
5-3 fit the old fashioned way by rebidding your 5 card suit as responder .
If you have a 6 card suit just leap to 4 ! I repeat ,
rebid your 5 card major to find the 5-3 fit. Do not use the relay & bid 3NT
as you are showing a slam try in partner’s
minor. The Wollfe relay also divides responders hand into two playing
fields. No slam interest if she used the relay & slam interest if she just bid
naturally.
Gerber is thrown
out using the Wolffe relay. A 4 club bid ( jump ) after a 2NT
rebid is a 2nd suit , a slam try & if partner opened 1♣ it
is a jump preference
slam try. This work around is due to the 3♣ bid being used as a relay.
Here
are 4 example hands with partner opening 1♣ , you
respond with opener rebidding 2NT.
1)
♠KJ10xx ♥xxx ♦Jxxx ♣x
,
2)
♠xxx ♥KJ10xx ♦Jxxx ♣x
,
3)
♠K109x ♥xx ♦J109xxx ♣x
4) ♠K109x ♥xx ♦x ♣J109xxx .
Hand #1 bid the relay , 3♠ & partner may
pass. Ditto with hand #2 except with hearts. The 3rd
hand partner will have no say as you are dropping her in 3♦ after the relay. The
4th hand you are bidding 4♣ after partner takes the relay and
partner has the option of passing if a 11 trick club
contract is too rich for her blood. In most cases she will carry on to 5♣
as we may have a big fit.
We
use the Wollfe relay to allow us to bid 2NT with a 4 card fit for partners major.
We feel that all balanced hands should initially be described with a NT bid
regardless of having a major fit. This allows us to have a jump raise of
partner’s major to game as “fast arrival” so based on distribution rather than
HCP’s. The only time you are allowed to break the relay
is when you have a 4 card major fit for partner. This solves the problem very
nicely.
Here
is the Bridge World standard which makes the 3♣ quite ambiguous to say
the least but with Wolffe relay overtones.
After a one-level
new-suit response and opener’s two-notrump rebid:
(a)
responder’s three-club rebid is artificial,
and opener bids three diamonds unless he has
three-card support for responder’s major (responder’s next bid up to and
including three of his original suit is nonforcing;
otherwise, responder’s next bid is a signoff if that is possible; otherwise, it
is a choice of games if that is possible; otherwise, it is a checkback for an eight-card major-suit fit if possible;
otherwise, it converts the three-club rebid into a natural bid in the minor
three diamonds over two notrump would not have
shown);
