It is not illegal though to have many full binds. Every player does this to move a piece away. The key is that the piece can escape. While with the pre bind full bind the piece cannot escape because he is stuck forever in a line and cannot turn any corners.
In full bind full bind the piece can turn corners and move about.
If the piece cannot escape in full bind full bind even though he has access to all ends of the board, it should be a draw.
D.B., You're right, perhaps I will admit, about what is the most ONEROUS kind of chasing. The "pre bind"/"full bind" definition addresses this nastiest kind, that's true. But the other chasing exists also. You can call "full bind"/"full bind" pursuit "not" chasing, and even say that it is "legal", but I submit to you that it is clear that it could go on FOREVER. To not include it in our chasing rule is to completely ignore one whole side of the chasing problem.
You say that the "full bind"/"full bind" piece being pursued can escape? But that's just it, in the "fb/fb"-only chase, the piece CANNOT escape. How can it? It does have more freedom of movement than the "pb/fb" situation, yes. It does have the ability to go around the board in any direction it chooses, certainly. But it CANNOT escape--not unless the chaser quits. A chaser from behind can continue to pursue, "full bind" to "full bind", no matter what direction the lesser piece moves. It could go on FOREVER.
All I'm simply saying is let's not forget this half of the POTENTIAL chasing threat in whatever reg we promulgate here. And don't give the "full bind"/"full bind" chaser the cheap draw just because of the lack of a rule to stop him.
The most important thing here is the numbers of binds to be allowed, both per incident and per game. I still say err on the side of the large number to be conservative.
