If using the standard suit preference signal, East should play C2 at trick 1 because it's crystally clear that West has a singleton club and C2 makes the suit preference more clear, though it doesn't matter on this board. In closed room, Burger made a mistake. The hearts might break 5-1. If that's the case Burger shouldn't lead the H6 because South might have singleton K, Q, T or 9. If he led H6, which was covered by singleton K, Q, T or 9, then it would leave dummy with J873 and North with KQT4 and declarer was unable to get a heart trick.

The defence in closed room was interesting. My guess is that, Goldman thought that Soloway led D5 from Qxx, which gave him an impression that declarer had QT98x Kxxx Kxx x or AT98x Jxxx Kxx x. Suppose declarer had QT98x Kxxx Kxx x, then declarer had 2 club tricks, 2 diamond tricks, 1 heart trick and at least 5 trump tricks (ruff the fourth heart with SK and leave QT98 in hand). Suppose declarer had AT982 Jxxx Kxx x, declarer had 2 club tricks, 2 diamond tricks and needed 6 trumps tricks, which could be provided by cross-ruffing. In any event, the contract seemed icy cold. So I guess Goldman was trying to confuse declarer. E.g., Declarer had QT98x Kxxx Kxx x. Being afraid of bad split in clubs, declarer might ruff the club with S8. Then after HK, ruff a heart in dummy, DK, ruff the last heart with SK, declarer has to get two trumps tricks from QT92. Declarer might lead a trump from dummy and play the SQ, which works when LHO has singleton J or small or trumps break 3-2. Of course, it's a postmortem analysis from a spectator's view. I really don't know why Goldman led a club at trick 5. Burger made a minor mistake at trick 9. His goal was to get 4 tricks from S K6 S AQ98 H -- H T D 9 D -- C J4 C -- He should ruff D9 with SQ (though it's not likely that Soloway led a diamond from Kx doubleton), ruff HT with SK, lead a trump from dummy and cover RHO's any trump. Since there is a safety play available, why not take the safe way?
