For the sake of completeness (and to anyone who found that the solution eluded them), the correct play was to
overtake the ♠K with the ♠A at trick 1, then play
♥A followed by ruffing
♥4 in dummy with the
♠Q.
N/S have 7 trump winners plus 2 Aces plus an "obvious" ruff in dummy. The problem arises if we instinctively let the
♠K in dummy win the first trick because there is no quick entry back to hand to ruff the
♥.
If you allow
♠K to stand, you will next have to play a low club OR the
♦A and a low
♦. You hope that opponents will lead another card in the minor suit and you can ruff that in hand. However, East (or West) will win return their second low trump when in with their first trick. This causes your ruffing trick to evaporate and the contract is now headed for a disaster.

Deals like this appear in card play textbooks. The illusion is created by the superfluous trump winners in North. This problem would have been an non-problem if North held
♠43 and South held
♠AKQJ109x --- everyone would win the first trick in the South hand and immediately secure the
♥ ruff.
