K of club lead follwed by small to ace club followed by 3rd club ruffed in dummy.
First thing if diamond breaks the contract is trival. so diamonds should break badly. Would you take the trump reduction line and go down if trumps break well?
Would you do it if the contract is not dbled?
Also if west preempted 3D and east responded 3S, should west bid 3nt or 4D?
Note: the trump reduction line wont work if west is a alert and presumly worldclass defender who of cos will insert the king spade when a small spade is lead to dummy without thought
