Solution

(a)      North wins, cashes a heart, and leads a diamond.  Already endplayed, East does best to win two diamonds and exit on the K.  North discards a heart on the second diamond and South wins with the A.  A club to the J is followed by a low spade, fixing East again.  East does best to exit with a club to the Q, which is followed by a heart to the A.  If East discards a low diamond, North exits with a low spade; otherwise North plays A and another spade.

(b)      East does best to win two diamonds and exit with the 8, covered all round to Northís A.  This time North discards a spade on the second diamond. At trick 4 North leads a low heart to 5 and J, East discarding a club.  West returns a spade to North and North exits on a low spade, endplaying East as South and West both discard clubs.  East gets out on the K.  South wins, runs the 7, then crosses to the K in this ending:

♠ AJ4

 K

 none

♣ J

♠ none

 Q

 96

♣ 109

♠ Q98

 none

 Q7

♣ none

♠ none

 6

 J5

♣ Q4

Whatever East discards, the J comes next.  If Eastís last three cards are the Q and two spades, South overtakes with the Q and puts East in on a diamond; otherwise the J holds and North leads a low spade.

An alternative defence is for East to win just one diamond before switching to hearts and for West to return a club after winning the second heart.  In that case South wins with the Q and leads the 7 in this position:

♠ AKJ432

 A3

 none

♣ J

♠ 10

 Q4

 986

♣ 1096

♠ Q987

 none

 AK7

♣ K8

♠ 5

 76

 J54

♣ A43

If West ducks the 7 and East discards a low diamond, the A comes next, forcing a spade from East.  Next comes the J, Eastís K being allowed to hold.  Now the only way for East to avoid leading away from the Q is to allow South to make the A and the J.  If West covers the 7 East can discard a high diamond but ducking the K works again.

See the solution to Competition Problem #4 for the recommended tabular format if you prefer not to write in English prose.
