John Armstrong and a curious end-play

John Armstrong died last month: he was a great player and a true gentleman. This is a hand John played which I saw on BBO; at John's table a curious end-play was possible.

Closed Room

Rees(N) & Kurbalija(S) v Rosen(E) & Jones(W). N/S bid 1NT-2C-2S-4S. West lead a spade and won the spade return. Now, West lead a heart to the King, and declarer drew the remaining trump, finessed CJ and claimed 11 tricks.

Open Room

Holland(N) & Armstrong(S) v Salisbury(E) & Tedd(W). N/S bid 1S-2S-3C-3D-3S-4S. West lead a club to the Jack, won the spade return, and played a diamond to the Jack and King. Declarer drew trumps, cashed CK, CA, DA, and lead a heart to the King and Ace; claiming 10 tricks.

If at trick eight, South continues to cash black cards, he reaches this position.

If West throws a small heart, declarer throws a small diamond from dummy and ducks H10 to West; dummy wins the next diamond and has a heart to play to HK. If West throws a diamond, declarer discards a heart from dummy, and East must throw a heart honour; declarer cashes DA and leads a heart to the King and Ace, winning the last trick with H10.

This ending has elements of a double squeeze, a guard squeeze, and a strip squeeze: I don't think I've seen anything similar before.
