The Bathurst team is leading against by a considerable margin in the USBF trials. 14 of those IMPs enriched them at board 60:

Both Meckstroth and Wooldridge played 6 notrump after South doubled a Stayman. Both took the club lead in hand (really surprised me that both Souths played the ten, I thought they good enough to play the jack) and played queen and other spade. South played the ten on the first round so Wooldridge finessed with the eight and could claim. Meckstroth played a top spade on the second round and duly went down. 

It was a deserved gain but not well deserved. Wooldridge’s play is superior. In the spade suit it seems to be about equal after the double but he has better chances for a squeeze if his play doesn’t work. Still he could and should have played better. Consider the case where his finesse looses. If South plays back a club or a heart the entries for the double squeeze are crippled. He must rely on the simple heart-diamond squeeze because he cannot cash the king of diamonds before runnning the spades.

A better play would have been to cash the top diamonds before playing on spades. In this case if South takes the second spade and exit in a rounded suit he can win in hand and cash the king of diamonds before running the spades. If South played a club it will be a simultanous double squeeze, if a heart a non simultanous one. With South having a 2326 distribution he would have felt the 14 IMPs difference.
