Hand Evaluation - Equal Level Conversion (
levels )
PITBULLS:
In my mind , an overcall shows a one
suited hand especially at the two
level & higher.. You have a multitude of toys to show all kinds
of two suiters , of course 3 suiters are handled
by a T/O double. Overcalls should be defined as showing a one suited hand.
Rules are made to be broken so with the wrong combination of suits
, you can overcall at the one level
with two suits . Normally done though when you do not
have too much defense. If
they open a minor , a double shows at least both majors . If they opened a major , a double shows at least the unbid major and other suit (s). Equal level conversion handles the
non shape T/O doubles. Bring back the double as opposed to the ambiguous overcall which hides 2nd suits.
Equal
level conversion is more than that though. It is a style of Bridge where converting to another suit at any level up to &
including the 7 level denies your suit & promises the bid suit & one
higher ranking. The bid at the same level is not an advanced Q bid with a fit in your suit. That just
does not happen playing an equal
level conversion style at any level.
Equal level conversion defines your overcalls as a hand with one suit & not
much defense. The concept defines your
doubles as defensive in nature with more than one suit. Ambiguity is reduced.
Say
you had this hand ♠KJxxx ♥xx ♦Ax .♣AKxx , they open 1♦ . You have two suits
but a 1♠ overcall is just a better bid than a T/O double at the
one level. What if they open 3♦ ? I would now choose a
double as it is more flexible
& I have equal level conversion
to protect me. If partner bids 3♥ , I will bid 3♠ . Since we are at
the same level , it does not show extra but shows spades &
clubs. This sequence gives partner an option
to bid 3NT with a little extra.
Overcalling 3♠ could be a disaster
resulting in a huge set or partner
might pass 3♠ with ♠x ♥Axxx ♦xx ♣Qxxxxx
&
other hands where 5♣ makes but 3♠ goes down. Bidding 5
card suits at the 3 level & passing should not be
an option with this hand. Partner might even convert your double for penalty !!
Still another advantage a double has over an overcall ! An overcall with a 5 card suit at the 3 levll
is so final & does not describe your true
hand.
What
about even higher levels where the
opponents have pre-empted ?. Here is where I feel an overcall must show
a one suited hand. The pre-empt has done its dirty
work so you can not have shape T/O doubles all the
time. Equal level conversion goes hand in hand with pre-emptive auctions from the two level
up to the four level. Double with defense
with two suits and allow equal level
conversion to sort things out. You bring penalty conversion into the
picture & bring your 2nd suit out of the
closet.
Here
is Tom Gandolfo in action tonight. ♠KJxxx ♥AKJ ♦Ax ♣ AKx ,RHO opens 3♦ nv
vrs vul. A double is
obvious so partner bids 3♥ . Bidding 4♥ is a mild underbid
so it would be nice to have the 4th heart for a 4♦ slam try. A Q bid
must imply a fit & be a slam try on these auctions. A double followed by
3NT would show the rock but not just a single stopper normally
. You do not have a perfect bid so I would try 3NT. At least I have
shown my balanced hand in the 2NT HCP range.
One
bid you can not make is 3♠ as that is equal
level conversion so is not forcing.
The old fashioned notion of doubling and bidding a suit to show a rock is extinct playing
equal level conversion at
any level. As Kiz Fung says “big hands
can take care of themselves” . With Toms hand , he had many options
to show a moose so he does not need the 3♠ bid as strong. It is
all the intermediate two suiters and 5-4’s that need help with equal level
conversion.
Equal
level conversion is not level
dependent. The approach just means “equal level” not low level. Some Q bids
rather than doubles are equal level conversion. You Q bid ,
partner chooses a suit & you convert at the same level. This means you have
that suit & one higher. You do not have partner’s suit. No more ambiguity.
