Ever since I wrote the Losing Trick Count booklet last year I have been receiving reports from friends and readers that using LTC has improved their bidding and made their decisions easier. Give it a try if you haven't already--your success will make you a believer!
The main thing to remember is: don't use it until you have found a fit with partner in the bidding.
I have always found it especially valuable to use when I have a decision to make in the bidding, such as whether to invite game (or slam) or whether to accept a game invitation. LTC provides a quick and accurate answer.
Occasionally I hear about a hand where LTC doesn't work. It's good to remember that LTC measures the number of tricks the partnership can expect to take most of the time. It doesn't measure certain winners, but only the potential of the hand--the number of tricks the partnership can be expected to take. It's not a panacea for all bidding problems, but is more accurate than other methods.
I used LTC while bidding this hand a couple of days ago in a pair game:
At favorable vulnerability, partner dealt and opened 1♣. RHO bid 1♦ and it was my call. As I liked my club fit and distribution, I made a negative double. LHO passed and partner jumped to 2♠. It went pass, pass and LHO balanced with 3♦, passed back to me.
While I didn't have much of a hand, I now counted my losers as we had a known spade fit (and probably a club fit as well). I added my 9 losers to the 6 losers partner showed with his jump to 2♠ and decided that we could probably make 3♠, so I bid it. All passed.
Partner had no trouble making the contract and actually made 4. Plus 170 was a good score. If I had only counted points I would have undoubtedly passed, but LTC helped me make the right decision.
See you at the table!
