Hand Evaluation – HCPS ( Trapping )
PITBULLS:
A common method of hand evaluation
is shown quite nicely by splinter theory.
If you have duplication of value opposite shortness , the offensive potential of the hand diminishes
and the defensive value increases. This is a common theme
for hand evaluation so is not just applicable
to splinters. The Bridge concepts of balancing
, trapping and D.S.I.P.
competitive double theory is
based on wasted values in the opponents trump suit. Take these two hands
♠Jxxx ♥Qxxx ♦AKQx ♣x , they open 1♦ to your right .
What do you bid ? 99 % of Bridge players will pass as they do not have a good bid with
the bulk of their HCP’s wasted in
the opponents long suit. Change your hand to
♠AKxx ♥AQxx ♦xxxx ♣x and you have essentially the same HCP’s but this time no wasted values in diamonds. I believe in
trapping when you hold the opponents suit with
wasted values .
However , when you do not have wasted values , I would
double with
this hand . Playing equal level conversion , I would scramble to 2♥ if partner bids
2♣.
Do not trap
when you just cannot figure out a bid especially vul vrs
not. A trapped hand in
today’s game is a descriptive call. The concept of trapping shows wasted values in the opponent’s suit which diminishes the
hand’s offensive potential. Like in negative double theory ,
partner will bend over backwards
with quick tricks to double in the balancing
seat to “protect” your pass. One level doubles converted can be
simply brutal for the opening side especially when they are prone to opening garbage.
A Tormentee
held a hand that everybody was getting into trouble. ♠AQx ♥AKQx ♦void
♣Jxxxxx , you hear 1♣ to your right. This is the wrong hand to trap as you do not have wasted values in clubs. You do not have a book bid , but passing should not be an option. The
reason why you can get away with
trapping with some big hands is that you have wasted values .
Generally your side can not make anything
& they go down a bunch. With this hand , partner
may not balance with hands that can produce a major suit slam & they still
can make 1♣ their way. Give partner ♠J109x ♥xxxxxx ♦xxx
♣void & you have a shot
at +1430 or even a grand slam in hearts . Give partner
♠Kxxxxxx ♥xxx ♦xxx
♣void & you have the same
slam opportunity as they are making
1♣ !!
Passing & backing in later is not
the way to describe this hand . You may not get a chance to back in as 1♣ can
get passed out or they find their diamond fit so get the auction up to high
levels too quickly for you. Passing and backing in later should show a club suit trap i.e. wasted values in clubs not just length in their suit.
The Tormentee
overcalled 1♥ , I made a
negative double so they bought the hand in a heart
partial. We lost 13 IMPS as everybody was getting into trouble with
contracts ranging from 5♣ in their 6-0 fit to 4♥XX for –1000.
Sometimes you must manufacture a bid
when passing is a poor alternative. This is hand
evaluation pure & simple. You do not trap without wasted values in the opponents
suit. A heart overcall was the best & winning bid by the Tormentee. Fixed again J . It hurts less when you are fixed by a Tormentee
though.
