Subject: When to stop searching captures?

Let say hypothetically that I have a program that is doing a simple
3 ply search, but will extend its look ahead for every capture.  The question
becomes, how far should the look ahead be extended?  The last time I wrote
a chess program (1987) I found that the program would examine frivilous
captures out to infinity if I didn't put a limit on it.  (I literally had
20 captures in a row.)

So say I limit the extensions to 2*N, where if N is 3 then 2*N equals 6.
Seems to me that this might not yield an accurate result and could still give
lots of frivilous captures.
