a)West cannot ruff because then you take 3 trumps independently, AS, and a 
diamond. 
b)West cannot pitch a spade because you then ruff and run the TS.
Ruffing when covered. You lead your good diamond and if west ruffs, dummy
is good. So you get a low diamond trick after all. Losing only a spade at the
end(or heart). 
c)So west must pitch a heart. And now you pitch a spade. East is immediately
endplayed. A heart lead sets up declarers hand(play low and ruff AH with JC
and return with a trump). A spade lead gives declarer two spade tricks and
he will take three clubs indepently.
  
Declarer can handle all possible defenses and make his doubled contract.
