Continuing a light-on-playing week, here's the first hand I've written about where I wasn't a participant.

I was watching the Cavendish pairs on BBO and the marquee matchup of Gitelman-Moss Levin-Weinstein rated to be interesting.  One of the pairs had a serious system drop:

Ghestem is a system that is designed to replace Michaels by showing both suits of a 2 suiter.   I won't explain the entire system, but when the opps open 1 Club, 2 Clubs is natural, 2 Diamonds is majors, 2N is reds, and 3 Clubs is pointys (diamonds & spades.)

So you pick up in 2nd all red:

KQ7 / JT6 / KJ96 / T92

Righty passes, you pass, lefty opens 1 Club and pard bids 2 Clubs, natural,  pass to you.

Fred Gitelman bid 2NT, and pard raised to 3NT. 

You've got a pretty nice hand.  Surely pard has a little something in hearts, or maybe they're 4-4 or 4-3.  Pard's clubs figure to run, maybe off the ace (the finesse rates to be working.)  This should be a systemic triumph, since most pairs won't have a natural 2 Club bid available. 

Or maybe not.

Brad forgot system (bid Michaels) with:

A8543 / AKQ72 / Q3 / 5

Even if the defense goes passive, +430 rates to be a poor result.  But Weinstein wasn't about to get this decision wrong and wisely underled his clubs from:

T96 / 9 / AT8 / AJ8764

-300

Hands like these remind us that great pairs make boneheaded mistakes too, they just make fewer of them and move on to the next hand when they do make them.
