How to make a 10 trick Stayman hand with heart and club losers
In a 10 trick contract you face two trump losers and a club and heart loser. The winning plan uses a heart lead from dummy, then cashing diamonds to throw West in with the lead to endplay, letting you ruff and ride to success depending on East’s duck or cover. This sequence preserves the approach of ruffing clubs in dummy and forcing West to reveal the remaining suit losses.
