This deal is from a Cheadle Hulme duplicate earlier this month.
After North had opened one diamond and South responded one spade, North sensibly raised to two spades even though it was possibly a four three fit. Those players who rebid two diamonds played there and most went one off, the one successful declarer still didn't score as well as two spades making. South passed two spades, making a thin game try at pairs is not advisable, just getting a plus score on the board should score well.
Playing four three fits is always interesting, sometimes drawing trumps and playing the deal as if in notrump is the plan, other times ruffing losers in dummy works, sometimes a cross ruff or just try to scramble as many tricks as possible. Players tend to panic a bit, but it is essentially no different from playing with more trumps.
Here West led a low club, declarer won in dummy and tried the queen of spades. With the useful eight and seven of spades declarer only needed to find one spade honour onside and trump a club in dummy to make the contract, with the diamond finesse as reserve. The queen of spades was covered and won by South's ace. South cashed two top clubs and trumped a club in dummy, then cashed the ace of hearts and played another trump. Eventually the diamond finesse lost but declarer had eight tricks, for a top score. Only one defender found the killing trump lead which prevents the club ruff.
