Subject: Counter move heuristic

Hi,
could someone please explain how to implemement the counter move heuristic?
I first red it in the Marcel Kervinck master thesis pdf document, but didn't
understand it, here is the citation:

"The counter move heuristic works by observing that killers need not be
constrained by sharing the same parent node. Often, a single move, defined as
(from,to)-tuple would generate the same refutation.
Counter moves are easily implemmented using a 64x64 table that can hold the
counter moves and that is indexed with the previous move."

(I couldn't copy and paste so I typed in the text)

Best regards,
Alvaro
