Another deal from the Manchester Congress Pairs.
Most tables played this board in four hearts, though three unsuccessfully attempted six hearts.
On the ace of clubs lead followed by a spade switch declarer won in dummy and played the diamond jack to the king and ace.
Declarer was now able to ruff a spade which East could not overruff and try the finesse against the diamond ten, to end up with eleven tricks.
Four pairs in four hearts made twelve tricks on various misdefences, but according to Deep Finesse twelve tricks can always be made, can you see how?
Scroll down for solution.
If West leads a high club honour, declarer has enough entries to dummy to ruff out the clubs.
On any other lead declarer can finesse against the heart jack in order to ruff out the clubs.
Alternatively she can ruff a spade in dummy, lead the diamond jack to transfer the diamond guard to West and then run hearts and spades to force West down to holding a high club honour and 10x in diamonds. Declarer now exits with a club and West has to play a diamond to declarer's Q9.
