Scoring: IMP
Say you play 3rd/5th leads (thus high from doubleton) and lead heart ten against 7♦. Declarer plays on a club-heart squeeze and fails, because you hold heart 9, but if you had Tx, you'd also lead ten and then the squeeze would work. So is it profitable to lead low from doubleton (even Jx and higher) against slams or is it just about this one deal?
