Play it yourself

The line below is one playthrough against one deal. To ask what a different card would have been worth — or what happens when the king sits the other way — take the same cards to the explorer, where you play all four hands and every card you could choose is priced. Nothing there is recorded.

The line

Played against West Q and East J8xxx. Not the likeliest lie — the one that defeats the most careless play, which is the one worth showing.

The same cards, a different target

A different number of tricks is a different problem, with its own best line.

Odds are the share of lies on which this line guarantees the target against best defence — the card that hurts you most, whether or not it is the card a book would play. An entry is counted each time the lead has to change hands, in either direction. The first lead is free from either hand — you broach the suit from wherever you are.
