Hand Evaluation – Dbls ( Guessing )

PITBULLS:

My partners & I have been developing D.S.I.P. theory since my first article on the subject dated August 2002 , 2007. We have blown many IMPS but gained many IMPS. We have learned from our mistakes so enriched the theory. 5 years later ( tonight ) I just blew a big pickup because I fell in love with my singleton in their suit. This is a big mistake playing D.S.I.P. competitive double theory , because the D.S.I.P. double was invented in part to find out if your stiff in their suit is really worth gold. The double prevents you from making a bad guess.

LHO opened a weak 2♥ on equal vulnerability (nv) , my partner overcalled 2♠ . They bid 3♥ so you hold ♠xx ♥x ♦K109x ♣AQ10xxx , what do you bid ? The opponents are bidding my stiff at the 3 level so the 30 HCP rule is in effect right ? I really liked my hand so I bid 4♣. This shows where I live , shows my offensive hand & helps partner make a decision if they bid 4♥. Wrong ! partner held ♥KQx opposite my stiff. A double by me says I want to bid something but I have controls measured in quick tricks in the other suits. Partner converts for penalty , we take 3 clubs , 2 spades & two hearts for +500. We were beat in 4♠ with a couple of diamond ruffs but it is a bad contract anyway.

Playing D.S.I.P. theory , you do not have to trust the opponents that they have all their HCP’s in their suits. Ask partner a question with a D.S.I.P. double . One of the reasons that D.S.I.P. theory was invented was to bring partner into the decision making process in competitive auctions. Let the system do the work for you . The double in effect says , partner do they have their HCP’s in their suits ? It works way better than guessing ! The bid catches bad bidders & speeders for you . %^&$%&

The splinter was invented to find duplication of value. This is not the only way though. D.S.I.P. competitive double theory allows you to determine duplication of value by getting partner’s opinion. A double says is my singleton in their suit duplication of value ? A double allows you to escape from making a bad guess & allows the opponents not to escape their bad bidding. That’s by far the best part of D.S.I.P. theory for me. Allow your system to help you from opponents bidding poorly.
