First, pardon the simplicity of the information I seek but I tried running a search on this but got nowhere. This forum's search engine was unsuccessful as XY is too short, chain produced like a million results and xy-chain produced nothing.

My question is how do you search for XY-Chains? Whatever I'm doing is not working. I'm jumping all over the place, wasting time and getting unproductive results. There must be a better way. I would love to hear ideas or techniques of how people are really using XY-chains. Are you looking for a common "pivot cell" first, two bi-value cells in adjacent rows, randomly picking a cell? What?

BTW, I've looked through several how-to sites and found some nice ones that explain how to solve the XY-chain, but that's not what I'm looking for. I know how the chain works. I know how to move from one cell to another. I'm just looking for ways to spot them quicker rather than just randomly selecting a cell and seeing where it leads. There must be some logic to using this technique other than, "Oh, here's a bi-value cell. Let's try this one." You know what I mean?

Thanks for any help you can provide.
