Throw-in Play

Throw-in Play
Upon the execution of a throw-in play, an opponent is intentionally given the trick. However, the lead thereafter will cost the opponent also one trick or more.
This play happens :
  • occasionally in NT contracts
  • But it happens more often when playing a trump contract

NT example: S is playing a NT contract. W leads with 5 ; S has 8 tricks up front; how is he going to play his contract ? Do you notice your 2 tenaces in and : the solution is to make W play into these tenaces ? How can you make this happen ?

Trump Throw-in.
This play is much more frequent, because it can have 2 main objectives :
  • force the Opp to play into your tenace (as in a NT contract)
  • let the Opp take the trick but he is then forced to concede a trick or tricks through a ruff and sluff play by the Declarer. This is also known as an Elimination Play.

Trump Throw-in
The success to Trump Throw-in :
  • The possibility of eliminating all the suits, except the ones that you need.
  • The possibility of carrying out a Throw-in play to the Opp that you need to play into your tenace : this can sometimes be both of your Opps, but not always.!
