Contract is 5♣ by south
Declarer just losed a second trick to East, so the trick count is 6-2.
This is what happens now:
East leads ♥2
South plays ♥K
West plays ♥4
North (dummy) plays ♥3
West says ouch er...
North (dummy) requests West to pick ♥4 up and change it
South (declarer) puts ♥K as winner and picks a card to lead to next trick
East comforts West saying: It doesn´t matter, you make ♥A in the end, 1 off. (claims 1 down)
South says no, I make the contract, ruff a spade and discard 2 hearts on diamonds.
East looks at all the cards and says, ok: then its 2 down.
How many tricks?
