Losing Trick Count (LTC) in bridge

The Losing Trick Count (LTC) in bridge is a way of evaluating the strength of your hand when you have at least 8 trumps between you and your partner.

the number of tricks you can make

Step 1: Count your losers

Only the first three cards in any suit are potential losers.
♠AQ9864 With this spade suit we can ignore the 864.

3 card suits

Looking at just the first three cards in a suit then, an ace will never be a loser.
♠A76 = 2 losers.

A King in a three card suit is not a loser because when the Ace is played you can throw a small card, keeping the King.
♠K76 = 2 losers.

A Queen in a three card suit is not a loser either because even when the Ace and King are played your Queen is still there.
♠Q76 = 2 losers.

So assume each Ace, King or Queen in a 3 card suit is going to take a trick and count the other cards as losers.
♠AQ6 = 1 loser
♠KQ6 = 1 loser
♠AK7 = 1 loser

And remember that only the first three cards in any suit are counted as potential losers.
♠AQ6432 = 1 loser
♠KQ653 = 1 loser
♠AK75 = 1 loser

2 card suits

If you have a 2-card suit, you have 2 potential losers. A Queen will fall on the second round so it's counted as a loser.
♠A2 = 1 loser.
♠K2 = 1 loser.
♠Q2 - 2 losers.

1 card suits

Count a singleton as a loser unless it's the Ace.
♠K = 1 loser.
♠7 = 1 loser.
♠A = 0 losers.

Count your total losers

Count the losers in the following hand...

1 spade loser, 1 heart loser, 2 diamond losers and 1 club loser.
total = 5 losers.

Step 2: Assess partner's losers

Here's how to estimate partner's losers.

Partner was the opener Partner was responding to your opening bid

The stronger the hand, the fewer the losers and the lower your Losing Trick Count.

Step 3: Combine your losers

Add your losers to partner's losers and subtract the total from 24. The answer will tell you how many tricks your side can expect to make.

Losing Trick Count in Bridge

Once North raises to 2♠, South can use the Losing Trick Count to determine how high to bid. Remember that it is only useful once you have found a fit. What should you do with this hand now?

Partner has a minimum opening = 7 losers. You have 5 losers, therefore 12 in total. 24 - 12 = 12. Check that you are not missing 2 aces using Blackwood and then bid the slam.

Ace vs Queen adjustment

This small and not well known adjustment will considerably improve your LTC calculations.

A32 is obviously stronger than Q32. Add half a loser for each queen. Subtract half a loser for each ace. So, A32 is 1 and a half losers, and Q32 is 2 and a half losers.

South's hand isn't so good. Too many Queens!

Losing trick count vs. counting points

The Losing Trick Count in bridge is much more accurate than than counting high card points but only when you have a trump fit.

High card points in bridge are used to calculate the strength of your hand and are the most common method of hand evaluation.

Losing trick count vs. rule of 20

The losing trick count isn't meant to be used for opening bids. If you're considering whether or not to open the bidding then the rule of 20 is the best method to use.

Learn how to use the Rule of 20 in bridge to decide whether or not to open the bidding on borderline hands. It's fun!

@graeme @tina for the adjustments mentioned near the end of this article do they only apply to suits with bare aces/queens? So Qxx is 2.5 losers but is KQx 1 loser or 1.5? What about shorter suits? Is Qx still just 2 losers or 2.5? Is AQ 1 loser or 0.5? Thanks

MY P at our local bridge club will be happy you are hoping me with LTC @Graeme. He's been after me to keep working on it. Great timing...thanks so much! And thanks for your question @Newtz2001 as Graeme's helpful answer is gold!

Thanks Graeme, this really helps get my head around it, now just have to put it into practice!
Hi, wondering if at all possible we could have some more practice hands for LTC. Need the practice.
I have played LTC for 50+ years. Like some you I also worried that LTC gave 1 loser for say both of Ax and Kx. I wrote to Ron Klinger about 30 years ago to discuss the concept of 1/2 losers and got no positive response.(although since that I have noted that Ron's one allowance of a half loser is Q x x). Since that I have written my own book on Light openers using LTC, using
A Q = 0.5 loser
A Q x =1.5 losers
K x = 1.5 losers
K Q x = 1.5 losers
Q J x = 2 losers
Q x x = 2.5 losers
A J 10 = 1.5 losers
You'd be surprised how often, adding the halves, you arrive at say 6 not 5 losers in your hand. The outcome of LTC arithmetic using these assumptions is astounding accurate.
