On defense, when leading a suit, we follow certain conventions such as “top of a sequence” or “fourth best”, all the better to help Partner figure out what is going on. But, once in a while, we lie. Consider this deal:
South West North East
Pass 1♠ 3♥ 3♠
4♥ 4♠ Pass Pass
North’s 3♥ showed a weak hand and a long suit (typically seven of them, occasionally only six). It’s a preemptive bid designed to disrupt the enemy auction. Nonetheless, E-W breeze into a 4♠ contract and Partner (North) leads the Heart Two, which you win with the Ace, Declarer following with the Eight. Does anything seem odd about Partner’s opening lead?
