Plan the play.

Please refer to yesterday’s comments for various suggestions. The deal comes from Kelsey-Bourke Bridge Quiz for Improving Players. The answer given there, p. 58 is

‘The safest line is to reverse the dummy and establish the clubs. You should succeed whenever the clubs are 3-3, and also when the clubs are 4-2 and trumps no worse than 3-1. Unblock the ace of hearts at trick two and then enter dummy to ruff a heart. Return to dummy with a second club and ruff the last heart. Crossing back to dummy with a trump, you ruff a club with the ace of spades. [In the example layout] the clubs fail to break evenly, but you simply draw trumps [3-1] and conceded a club, leaving dummy high.’

Having set about the hand pretty much as has everybody else, but knowing that I was up against two excellent analysts, I gave the hand to Robby van Riel, who played it thus:

Diamond ace, diamond ruff, heart ace diamond ruff. If diamonds are 4-3, then spade king. If everybody follows you are cold. If spades are 4-0 heart ruff, cash the ace and king of clubs, heart ruff, diamond ruffed, and SA9 must win – this is a cute ending. If someone pitches on the second diamond, heart ruff, club ace and king, heart ruff, diamond ruff, club ruff with the spade ace, diamond ruff and one of S98 makes a trick by weight.

See you Monday.

    if west is 4432 then the van riel line doesnt work as west ruffs the fourth round of diamonds low in front of dummy thereby avoiding the endplay

      You forget that the fifth diamond is high.
      It does not matter whether the defense looses a trick by a trump endplay or by the fifth diamond itself.
      However, I am not sure whether the line is really better than the cross ruff line by khokan
      As I understand van riel’s line it tries to avoid the main danger, clubs being 5-1 when everything else breaks.
      However, against that if somebody is 2-2 in the minors, a club discard on the third diamond might hurt.

        Sorry you were right, because the play was

        If spades are 4-0 heart ruff, cash the ace and king of clubs, heart ruff, diamond ruffed, and SA9 must win – this is a cute ending.

        where declarer ends up in dummy.

        I suggest

        If spades are 4-0, cash the ace and king of clubs, heart ruff, diamond ruffed, heart ruff.

        Now the endplay can be avoided, but west would still not get more than one trump trick.
