East defends suboptimally on this hand, allowing me to make on an incorrect line. After DK lead, south can draw two rounds of trumps, then play ace and a club. East wins and plays a third round of clubs, which subjects W to a simple squeeze. East needs to play a diamond to destroy the threat.

True, that is a bug in the defense but I am still very impressed with the overall quality of Bridge Master problems.

As an aside, I definitely took this line from the viewpoint of a tester. I would never take such an inferior line in reality. Haha. Ha. ha.

There are a few hands which don't punish you for an inferior line. If you spot something this straightforward on Level 4, just consider it a test to see if you can see things from the defender's point of view as well.
