Starting on left, your side doesn't bid:
1C 1S
2D 3C
5C 6C
3C GF, 5C fast arrival. Do you X? What % of the time do you expect to beat them?

IMO _X = 10, _P =6
Declarer is probably short in spades, since, with a doubleton, he would mark time with 3♠. Hence the contract is a probable make, Nevertheless, without a ♠ lead, we are unlikely to defeat the contract. And without a double, partner is unlikely to lead a ♠. That is the point of Lightner Xs. Declarerer XXs and makes an overtrick? I apologise again :)
