W leads J♣, declarer wins. ♠ to K, E wins with A. ♣ return, declarer wins. Declarer draws last trump, W discards ♣. So this is where we're at:
Kelsey's recommended play is 5♦ from declarer, then finesse 9♦ if W plays low. I'm struggling to get my head around this, I understand that E can't have both A♦ and K♥ or they'd have opened the bidding because we've already seen A♠ and implied Q♣, but I still can't get from that that declarer should risk E having the 10♦.Sometimes I think Kelsey picks weird plays just for the sake of it.
