The Cross-Ruff By John Brown. Example of: “Winning Tricks” by John Brown

In cross-ruff the aim is to make your trumps separately.

Throughout the play of the hand you may not be able to lead safely even a single round of trumps, and if you have to give up the lead you may be sure your opponents will lead trump.

If you have four trumps in each hand and are fortunate enough, because of favourable distribution to be able to make each of them separately, it is a highly profitable procedure.

The Cross-Ruff often requires great care, the entries for the plan must be counted, You must guard against an over ruff by, if necessary and when you can afford if, trumpling high.

No matter what the adverse distribution, declarer need only lose one trick. He should ruff high in each hand, ruffing his spades with the Heart SuitK and the Heart SuitJ, and the diamonds with Heart SuitA and the Heart SuitQ.The last spade is ruffled with the Heart Suit9; this will draw West’s Heart Suit10. But dummy’s Heart Suit7 will become in a winner.
