¿Como lo haría?
La mejor línea no se destaca aquí. Tres líneas posibles se consideran a continuación, yo estaría encantado de saber si un lector considera que una sea demostrablemente superior.
1) Esta fue mi eleccion. I know many would prefer to start bidding the hand. I belong to the, easier to handle school, two over one creates a game-force. Over palo intervention I pass, being quite certain a negative double (with forcing free-bids) will only cause confusion. Playing non-forcing free-bids, a minimum bid in corazons is easy over palo intervention. Over 1NT, the top-heavy natural non-forcing 2
is preferable to double. It is not hard to construct a hand where you make 4 and they make 1NT.
Oeste led a diamond to East’s 
K and East returned a trump. My partner’s line was successful but I am by no means sure it was the best. Superficially, the spade finesse looks bad value because it costs you a trick if it loses and one comes back, you do not get a diamond ruff. But there are other things to consider, including the trump palo itself, and you will gain a tempo.
Declarer won in hand with her 
A, ruffed her diamond and led a corazon to her K. Her J was a good card, but the K was taken on her left. Oeste returned a corazon, but almost certainly would have returned a trebol had he not held the 
K. Declarer must finesse and will be lucky to survive if it loses. In fact a corazon came back. Declarer won it in dummy and played a third corazon, luckily for her won on her right. Declarer ruffed the diamond continuation, drew the trump and claimed. What do you think of the line?
These are my thoughts. A trump back is almost mandatory wherever the K is. With 18 points missing there is room for either black king to be in either hand. You can play for and make with them both wrong, but you will need either luck or help. Consider your line in that case. (Your line may involve playing the Q off dummy to preserve entries, after you have grabbed your A and ruffed your diamond.) Simplicity appeals to me. Play for one king to be right. When the spade finesse loses and a trump comes back, draw the trump and take the trebol finesse. Return to a high corazon and repeat it, cash the ace and ruff one to establish the thirteener. You can dispose of your corazon and diamond losers.
How Would You Do It?
The best line does not really stand out here. Three possible lines are considered below, I would be delighted to hear if a reader considers one to be demonstrably superior.
1) This was my bid. I know many would prefer to start bidding the hand. I belong to the, easier to handle school, two over one creates a game-force. Over suit intervention I pass, being quite certain a negative double (with forcing free-bids) will only cause confusion. Playing non-forcing free-bids, a minimum bid in hearts is easy over suit intervention. Over 1NT, the top-heavy natural non-forcing 2 is preferable to double. It is not hard to construct a hand where you make 4 and they make 1NT.
