The Kachuful final trick calculation begins with wins already secured.

If your call is two and you have one, the last trick is necessary.

If you already have two, winning it produces a miss under exact-bid rules.

Suppose you hold the final A♦ and must follow diamonds.

You cannot choose to pass because you have already reached two. The earlier choices that left this ace alone created the forced ending.

Use the Kachuful final trick calculation before the final card, while alternatives still exist.

Look one or two tricks ahead and ask whether the remaining hand can meet the target legally, rather than hoping to change the rules at the finish.
