Combatting Preempts

by Richard Pavlicek

Winning combat tactics for the bidder who’s in trouble?
Parry left, parry right, escape the final double!

On each of these 10 problems, your right-hand opponent (RHO) opens with a preemptive bid, and you are presented with two reasonable options. If you would do something else, don’t admit it, as I’d have to flatten you with a flying scissors kick.

Choose your calls then click “Score Me” to see how you did. If you finish plus IMPs after 10 boards, consider yourself a black belt. At the end you can view the actual deals and see how two experts bid differently in each case.

Warning! My whole body is a weapon, so don’t try any funny stuff.
