Treasure Mine - Systems & Style - Chapter 1 - Australia USA - Part 3 of 3

(The recent world championship gives us a treasure trove that can be examined to study systems and style implications for success - we are looking at Australia USA here)

The match was 36-5 for Australia when board 10 shone:

Compton open 4D on the 7-5, if "6-5 stay alive", then "7-5 is get alive" and 4D woke everybody up. After 4D-4H-5D-5H;-?, Compton bid 6D unilaterally - we can see that 5H doubled runs into the clubs offside and repeated diamond plays can reduce the South hand to mush. Against 6D, NS can take a heart and a spade, for down one - nice - except Mullamphy led the club ace which set up the club king, and that was +1540.

In the other room, East opened 1H showing spades. NS competed in their ten card fit, and East never mentioned his seven card suit. +650 was nice, but still losing 13 IMPs.

The 4D, then 6D sequence worked this time, but I can't imagine Hamman was happy with this style - especially one that takes him out of the decision making process.

With the match 39-18 for Australia, board 14 was the final IMP exchange of the match:

East opened a 15+ big club, Meckstroth came in with a healthy 2C overcall, West had nothing to contribute, and Rodwell bounced with 5C. This left East with a little in extras, and a club void. He doubled and when partner started with a club (reducing the NS hands down to 5-5 in trumps) Meckstroth set up the 5th spade and that was +550 - a heart lead would have set it.

This was the closed room auction. Playing in 5D doubled would have produced a cute result - +550 for both USA pairs. Instead Compton ran back to 5H, which looks like he didn't trust Hamman's pass of the double. According to the vugraph play record, Compton played hearts with ace and another, losing to the heart king. Now 5H is down, but not so fast. After winning the heart king, North played a club, ruffed by East, who then played the diamond 3. South covered with the diamond 5, and declarer covered this with the 8 (saving the diamond 7 for a later beer). South's failure to play any diamond but the 5 reduced his diamond tricks to one and 5H rolled in for +450 and 14 IMPs.

The final score was 39-32 Australia in a match that showed some of the strengths and flaws of each team.

    On the first deal where Compton bid 6 diamonds, if he's going to bid at all, maybe 6 clubs? The last thing he wanted to do was push them to a slam that makes because partner had no clue what to lead.

    It would make an interesting Master Solvers Club (The Bridge World) problem - pass, 5S, 6C, 6D all options - only if the panel would accept the 4D opening. 5S might work - you get to a playable spot if partner has spades, and if the opponents bid 6H, now you double to say "don't lead anything I have bid so far"
