When you need an extra trick by ruffing in dummy
Board 9 Dlr N EW Vul
NORTH
South opens 1ª in third seat, North makes an invitational jump to 3ª with support and 11 TP, and South accepts with 15 TP.
West leads ©AKQ and switches to a spade - giving nothing away. (Any switch is okay on the actual hand.) Declarer sees the trumps are breaking 4-0, always a little uncomfortable. But there are nine top tricks, and another can be made by ruffing a diamond in dummy, the short trump hand.
All trumps cannot be drawn immediately (or there will be none left in dummy). The ruff will have to be made first. And all will be well as long as West holds at least two diamonds.
An easy one as long as you think it through from the beginning. 10 tricks and +420.
Board 10 Dlr E All Vul
NORTH
South would definitely open if ¨A were ªA (points are always better in your long suits) but may well choose to pass here. West is happy to open 1¨ with that excellent 6-card suit. East's response of 1ª keeps NS out of their 8-card fit. West, with a minimum single-suiter, rebids 2¨ and East is happy to leave it there.
North leads ©K. Declarer can see six losers - two in hearts, one in diamonds and three in clubs. And there are only seven sure winners - two aces and five trumps after the ace is taken. Where can an extra trick come from?
A successful spade finesse (a 50% chance) will give you the eighth trick and at the same time a 'parking place' for one of your losers.
Do you play trumps first? No, because alert defenders can then take six tricks on the trot and you will be one down.
Thus win ©A, play ªJ overtaking in dummy with ªQ in order to gain quick access to ªA, pitch a loser, and then play trumps.
Another case of finessing for possible success, or not finessing and surely failing. You make 8 tricks and +90 (2x20 +50).
