My partner led his singleton ♥2. Fortunately, I have been around awhile, and I recognized a classic deceptive play. Declarer played the ♥10 from dummy, and I won the ACE and returned the ♥8.
Now, declarer should not fall for this play, but she took the play at face value and pitched a club. Down 1.
