I was recently looking at several threads where a X of a cuebid asked for partner NOT to lead that suit. When and where does this apply? What criterions must be met? etc... Any help here would be appreciated!

Yes, another issue that is common is the double of a splinter, should it be a bid that asks for a lead of another suit or suggest a sacrifice in the splinter suit.

I don't think this meaning for double is ever standard.

However, a number of partnerships have agreed that if our side has bid a particular suit (i.e. opened or overcalled or bid and raised) then double of a cuebid of that suit asks for a different lead. The reason is that this suit would be the normal lead, and double potentially gives the opponents more space, so it makes sense to reserve the double for the rare occasion when we desire a different lead.

1. We open a major
2. We overcall
3. We preempt

Beyond that its a function of agreement. I;ve had mixed results with having a raiser utilize these doubles.
