D.S.I.P. Balancing Principles
PITBULLS :
Balancing obviously should be thought of
for D.S.I.P. purposes to when they balance & also after you balance. When partner fails to
respond to an opening bid & a competitive auction ensues , penalty
doubles apply not D.S.I.P. doubles.
This is the "pre-empt" principle as partner already knows a
great deal about your hand anyway since you passed. This principle also applies if partner passes originally in
a competitive auction & comes in belatedly or supports partner later
in the auction. D.S.I.P. theory does not apply.
When your side balances, you can use D.S.I.P. doubles to
clarify the situation. You hold ♠Jxx ♥Axxx ♦Q10x ♣Kxx and the auction goes 1♥-3♦-3♥-4♦
P- P - ? . This is the
semi-balancing balance of power
D.S.I.P. double.
You
have the 4th heart for offensive purposes with maximum defense for your
previous bid , so you should double. 4♦ X
goes for 500 , 4♥ went one down !
Balancing is a very ambiguous art form
so any help in clarifying the auction is gratefully accepted . I held ♠A10xx
♥Ax
♦A109x ♣xxx , the auction
went
P |
P |
1♣ |
P |
1♥ |
P |
P |
X |
P |
2♦ |
2♥ |
? |
This is a time to use the D.S.I.P.
double. You have defense & you want to compete to 3♦. If partner has a trump stack in hearts , this
contract doubled will be the optimum spot.
When partner balances & the opponents
make a jump rebid , a double is always D.S.I.P. This is because in the balancing
seat , partner does not promise perfect distribution soits very rare that you
will catch someone with a trump stack your direction. 1♦-P-P-X 3♦-X is
D.S.I.P. so does not show diamond
values.
When you have a good hand but a bad
suit , the safe approach is to balance rather then giving the
opponents the option for a penalty double by bidding directly. I held this hand ♠KJ109 ♥K10xxx
♦KQx ♣x and the auction went
1♦ |
P |
1♠ |
P |
2♣ |
P |
P |
2♥ |
P |
P |
3♣ |

Sounds like the opponents are in a 4-4 fit
with a 4 –1 break . I would like to compete further with my hand so I make a
D.S.I.P. double. Partner has ♠xxx ♥Jxx
♦Axx ♣QJ108 & converts for +500 . Change his
hand to 4 small clubs and 3♥ has a good
chance.
Support doubles & redoubles go hand in
hand with D.S.I.P. The purpose of a
support double or redouble is to show a 3 card fit with partner. I held ♠Axx
♥Axx ♦AQxx
♣xxx , the auction went 1♦-1♥-1♠-X XX with the double alerted as a systemic heart
raise. I redoubled to show a 3 card raise , the opponents leapt to 4♥ . Around to me again & I am vul against
not vul but 1 have 3 1/2 defensive tricks. I make a D.S.I.P. double saying I
wanted to bid 4♠. Tom had ♠KQ10xx
♥Jx ♦109xxx
♣x and we get to a beautiful 620.
Both not vul so this auction shows the
D.S.I.P. 2nd double in action . Tom held ♠x ♥Q1098x ♦AKx
♣AQxx & the auction went
1♠ |
X |
2♦ |
2♥ |
2♠ |
3♥ |
4♠ |

This is a classic D.S.I.P. double in the pass
out saying I have lots of defense so I would not mind if we bid 5♥ or if your hand is defensive lets play 4♠x . I would bid 5♥ which
makes unless they get a ruff. 4♠ makes so its a win
- win.
When they balance after we open the
bidding , we play the “over–under rule”
. If the double is in front of the bid suit , it is D.S.I.P. If behind the suit , the double is penalty.
This principle applies to the overcalling side also. We can not make a penalty
double in front of the suit in the balancing chair . BJ held ♠Jx ♥Qxxx ♦Axx ♣xxxx
, they opened 1♣. I overcalled 1♠ & they doubled with a pass by
BJ. Opener bids 2♣ so I compete with 2♠ which gets passed around to
opener who bids 3♣. This bid gets passed around to BJ who doubles in the
balancing chair. This double is not penalty by the “over/under rule” . I bid 3♠
which is cold for +140 .
