I don't think anybody will lead anything other than a high spade. K ENT Partner holding Q7532 and no side entry will be ticked if I lead the 8 . I lead the K . The tank suggests a heart lead, since with a big hand and two heart stops, he'd've bid it faster. I think I'll take a look at dummy and lead a spade.
Small spade lets it make.
Minor suit lead gets it one. Given how light this partner overcalls and the failure to make a takeout double, it seems that bidding 1 is asking for trouble, but it's close.
