9.6 Throw in 

Don't grudge a hen where you may get a goose...


   


 


 


 


Throw in is an end play. Giving a trick to the opponent, for a return which will supply more tricks is called throw-in..

Look at the hand diagram at the left. Suppose declarer (South) leads from dummy.. If he plays J for a finesse against queen, he will lose this trick. If West continues with a club, declarer will also lose another trick to the queen of hearts. So, by finessing declarer can make four tricks.. 

Instead, if declarer draws AK of either suit followed by an endplay (throw in) on the third round, West can not find a safe exit. He must surrender the last three tricks.  So, by preparing an endplay declarer can make five tricks..
