More Wastage

Against spades (declared by South) West starts with ♥ A-K-Q, then a heart, ruffed by East. East then cashes his ♣ A-K-Q, then leads another club, West ruffing with the ♠ 10, which promotes the ♠ J in East's hand, giving the defense eight tricks.

Against hearts, West leads the ♥ A-K-Q then exits in hearts to North. North can take three spades, but has to give East an entry, and the defense gets five hearts and three clubs.

Against diamonds, West starts with two top hearts, then a heart ruff by East, and three top clubs, followed by a club ruff and a fourth heart, ruffed by East with the ten - essentially the same promotion as when defending the spade contract.

Against clubs, the defense takes three hearts, East pitching diamonds, then a diamond ruff and three top clubs, ensuring East/West score five trumps and three hearts.

Against notrump, West starts with three top hearts, East pitching diamonds, West then exits a heart to North, and both North and East have only black suits. East eventually gets three clubs and a spade, for a total of six tricks.
