Triskaidekaphobia

Formidable foe or kissing cousin,
All beware the baker’s dozen!

As West, you are the opening leader on these 13 deals from 2013. Decide which of the 13 cards you would lead, then compare your choice with the experts who faced the same predicament and led differently. Keep track of your IMPs won and lost. In case you’re not overcome by fear already, remember that bridge is a timed event. You have 13 minutes!

I’ll start you off easy with only 2 IMPs at stake on the first hand:

Fleisher of USA2 led the D 8 (made 3 -400) +2 IMPs.
Other winning leads: S A-Q-10-8 D 7-3 C 7-3 +2 IMPs.

Campos of Brazil led the H 6 (made 5 -460) -2 IMPs.
Other losing leads: H K-J-8 -2 IMPs.

To keep score, find the IMP result of your lead and keep a running total. If your lead is unlisted, it is mediocre (worse than the winners but better than the losers) so take a push (0 IMPs). Goal is to finish plus.

Winning leads are determined from the actual deal and are not necessarily correct in theory or the long run. To qualify as an “other winning lead” it must fare at least as well as the actual winning lead if both are judged on a double-dummy basis. Similarly, “other losing leads” fare at least as badly as the actual losing lead. Results and IMP scores are from actual play, not double-dummy.
