Today I presented 3 hands, which you find in this movie:
#4 You count 11 sure winners in 6NT. You need 1 more trick.
There are 2 line available:
1) Try the heart finesse and hope for hearts to be distributed 3-3, if the finesse doesn't work.
2) Try the diamond double finesse.
The double finesse has a chance of 75%
The heart finesse has 50% and the chance that hearts are 3-3 under the precondition that the heart finesse is wrong is half of 36% = 18%.
So the chance adds up to 50%+18% = 68%
Therefore the double finesse is superior to the heart finesse.
We'll come back to this hand in the next session.
#1 Is an example where it is a must to pull the trumps at once. Remind: When you are planning a suit contract always ask you the question: Are there any reasons NOt to draw trumps at once? There are a lot of reasons possible. Marty Bergen sez, that in about 40% it is wise to postpone to draw the trumps.
#3 Is a choice which minor to develop. You have 7 sure tricks in the majors and need 2 more.
You have after the lead only 1 stopper left in spades.
Diamonds provide only 2 extra tricks (but that's enough). To promote the diamond you'll lose the lead only once.
Clubs will provide 4 extra tricks but you'll lose the lead twice in the establishing process.
Therefore you must attck the diamonds!!!
