Improvers Week 11 The Losing Trick Count (LTC)
LTC • We have used mainly HCP for decisions on what to bid • Works very well for NT contracts • But not good enough for suit contracts • We must consider the value of shape • LTC allows us to evaluate all hands • Giving more accurate suit bidding
Calculating the LTC • Count up to 3 cards in each suit • More than 3 discount lowest • Any that are not A K or Q are losers • Singleton K or Q is a loser • Doubleton Q is a loser • Bare Q is a ½ loser (Bare is Q without A K or J i.e. Qxx)
Calculate the LTC A J T 4 3 • How many losers? • 2 • How many losers? • 1 • How many losers? • 2 • How many losers? • 1 • Total • 6 K Q J 3 2 4 3 3
LTC • The lower the LTC the stronger the hand • Provided you find a fit! • You must not use LTC unless you have agreed a suit!! • A weak 1 of a suit opener would normally have a LTC of 7 (used only as a guide) • 1NT opener is very often 8 • Sometimes 7 with a good HCP count • So lets calculate the LTC for a number of hands • And look at the HCP count as well
Calculate the LTC A J T 4 3 • How many HCP? • 11 • How many losers? • 2 • How many losers? • 1 • How many losers? • 3 • How many losers? • 0 • Total • 6 K Q J 3 2 4 3 2
Calculate the LTC J T 5 4 3 • How many HCP? • 7 • How many losers? • 3 • How many losers? • 1 • How many losers? • 2 • How many losers? • 1 • Total • 7 K Q J 3 2 4 3 3
Calculate the LTC A K Q 4 3 • How many HCP? • 15 • How many losers? • 0 • How many losers? • 1 • How many losers? • 2 • How many losers? • 1 • Total • 4 K Q J 3 2 4 3 3
Calculate the LTC A K Q 4 3 • How many HCP? • 19 • How many losers? • 0 • How many losers? • 0 • How many losers? • 1 • How many losers? • 1 • Total • 2 K A Q J 3 2 4 3
Calculate the LTC Q J T 4 3 • How many HCP? • 9 • How many losers? • 2 • How many losers? • 2 • How many losers? • 2 • How many losers? • 1 • Total • 7 Q J 3 2 4 2 K 3
Calculate the LTC A K J 3 • How many HCP? • 18 • How many losers? • 1 • How many losers? • 1 • How many losers? • 3 • How many losers? • 2 • Total • 7 K Q 2 4 3 2 A J 3
Calculate the LTC A J 3 • How many HCP? • 17 • How many losers? • 2 • How many losers? • 1 • How many losers? • 2½ • How many losers? • 2 • Total • 7½ K Q 2 4 Q 3 2 A J 3
Note • The Losing Trick Count is related to shape not point count
LTC • We have a maximum of 12 losers • So does Partner • Total of 24 losers possible • In an agreed major: • With 14 losers between us game is on • With 15 game is unlikely • With 16 we want to stop at the 2 level • With 12 we should consider slam
LTC • If partner opens 1 of a suit assume 7 losers • With a major suit fit and • 9 losers raise to 2 • 8 losers raise to 3 • 7 losers raise to 4
Using LTC as responder A J T 4 3 • LTC? • 6 • Partner opens 1 • Combined LTC is 13 or better • Bid? • 1 • If partner re-bids weakly bid 4 • If partner re-bids stronger bid 4NT K Q J 3 2 4 3 3
Using LTC as responder T 9 5 4 3 • LTC? • 7 • Partner opens 1 • Combined LTC is 14 or better • Bid? • 4 • With only 5 HCP! • LTC takes account of shape K Q 4 3 2 4 3 3
Using LTC as responder Q J T 4 3 • LTC? • 8 • Partner opens 1 • Combined LTC is 15 or better • Bid? • 3 • Invitational • Partner can bid game with LTC 6 Q J 3 2 4 3 2 K
Using LTC as responder A K J • LTC? • 7 • Partner opens 1 • Combined LTC is 14 or better • Bid? • 4 • With 18 HCP it looks great but too flat for more K Q 3 2 4 3 2 A J 4
Building up the picture • Opening bid assume LTC 7 • Weak response assume 9 • Re-bid shows LTC of 6 and 5‘s • Responder bids 4with LTC of 8 and 3‘s 1 3 P P 1 P
LTC - Summary • LTC is more accurate than HCP for suit contracts • It takes shape as well as strength into account • Much better for raising suit bids • 1 of a major, 2 of the same major is better if it shows 9 LTC rather than 6-9 HCP • 1 of a major, 3 of the same major showing 8 LTC is very useful • Remember the joint LTC for game is 14
LTC - Summary • SO: • 1 major, 2 of the same major shows 9 LTC • 1 major, 3 of the same major shows 8 LTC • 1 major, 4 of the same major shows 7 LTC • 1 major, 4 of a minor agrees the major and shows more than 7 LTC • This is a Splinter or Cue Bid in the minor by agreement. (Separate lessons)
