Hand Evaluation - Negative Free Bids ( Overcalls )
PITBULLS:
D.S.I.P.
doubles are obviously forcing bids
unless the contract gets converted holding the opponents trump. I have never
liked “negative free bids” directly as it complicates the 2/1 structure &
negative double theory. However , when we overcall at the one , two & three level & they interfere , we
should play negative free bids .
We can make a D.S.I.P. double with all
good hands that you do not want to
Q bid. This is one of the advantages of
D.S.I.P. theory .
You do not need free bids to be forcing one round when you have a D.S.I.P.
double available , so you are allowed to compete, setup
sacrifices or just get in a lead
director . The D.S.I.P. double or
Q bid does the rest. You do not
need 3 forcing bids in
competitive auctions where you have a D.S.I.P. double ,
a Q bid or a bid in a new suit all forcing . This is overkill. The new suit forcing is not needed.
If
RHO does not interfere , this eliminates your
D.S.I.P. double so a new suit is a
one round force. Let’s take some
example hands where partner overcalls their weak two with RHO interfering The
definition of a negative free bid is that your bid is simply not forcing .
2♦-2♠-3♦-?
♠5 |
♠5 2 |
♠9 7 |
♠4 2 |
This is the
classic “negative free bid” . You paid your card fees
so bid 3♥ non forcing
Since 3♥ is a negative free bid , you must make a D.S.I.P. double . Partners has ♠AKJ10x ♦xx ♦KQx ♣xxx
so you
catch them speeding +800.
Classic
D.S.I.P. double , I have cards & do not know what
to do. Do something intelligent partner & may the force
be with you

Negative
free bids apply at the 4 level also . 4♣ is not forcing but not suicidal either.
At the one level , your D.S.I.P. double tends to be “snap
dragon” or just HCP’s . A free bid is negative and not forcing one round.
At the 3 or 4 level ,
same rules apply. When you have a D.S.I.P. competitive double available, none of your “free
bids” are forcing not even one round.
3♣-3♦-3♥-3♠ ♠AQ109xx
♥xx ♦xx
♣xxx Why not bid 3♠ , it’s not forcing.
With a stronger hand double first & bid spades.
