GM estimator..yes it is..I also wish we had a way to know when good M5 pinchers are setting up.Have considered the idea I had several years ago which never panned out for lack of participation which I called an Adopt-A-Pair program.Each participant would alert the board when a pair they choose to watch was setting up as a probable trade.Seems to me this would work very nicely but only if those involved commited to diffrent pairs.Wouldnt do much good if we were all on A/U for example for obvious reasons.But would be nice if we had participants in at least 5 or 6 different pairs that would give pincher alerts.
