Many ways to bring home the contract

Last night I played online bridge in Bridge Base, famous with BBO. I found out an interesting board as below. You West Partner East

You	North	Partner	South
1H	pass	2H	pass
4H	pass	pass	pass

Here are the complete deal.

	Dummy
	♠ K 7 5 2
	♥ J 8 7 2
	♦ Q J 7
	♣ 8 2
West		East
♠ AJ109		♠ 8 6 3
♥ Q 10 5		♥ K
♦ A1065		♦ K9832
♣ 7 6		♣ KJ54
	Declarer
	♠ Q4
	♥ A 9 6 4 3
	♦ 4
	♣ A Q 10 9 3

I have to bring the game contract in heart. West start with ♣ 7. After winning East' ♣ K, I play Ace of trump and continue. West win the 2nd round and play a third heart. I won in dummy and finesse club to bring home the contract. On the other table, West start with ♦ A and continue. South ruffs and then play the Ace of trump. When the King drops from East, South continues with a small spade. West is in dilemma. If he plays the Ace, then declarer just need a club finesse to land the contract. Because 2 more club loosers can be discarded from diamond and ♠ K. So, West plays small spade. Won with the King, declarer then plays the ♦Q to discard his ♠ Q. Finesse club and cross ruff club and spade and West discards all his spade during the process. Declarer has 9 tricks so far and just need 1 more trick. Here are the 3 cards ending when declarer play spade from dummy.

	Dummy
	♠ 7 5
	♥ J
	♦ -
	♣ -
West		East
♠ -		♠ 8
♥ Q 10		♥ -
♦ 10		♦ 9 2
♣ -		♣ -
	Declarer
	♠ -
	♥ 9 6
	♦ -
	♣ 10

When East play ♠ 8, declarer knows that the 8 is the highest spade. If he ruffs, west will overruff and draw his trumps, so he discards his club winner. If trump was 2-2, then he is safe as he will get his 10th trick. If East started with his lonely ♥K, then by discarding his ♥J will win en-passan. So, there are many ways to land the contract.
