Coup Classique

From:   Paul Epstein
Date:   10 December 2006
Subject:   Defending against a coup classique

The coup classique generally seems fairly easy for the favourite to
play, but the defender has lots of choices.

For example, if the defender recovers and puts two on the bar, when is
the correct time to redouble (money play)?  When should this redouble be
taken?  Assume that the player with two on the bar has the other 13 off.

The checker play questions seem more interesting, and there may
possibly be more equity involved.

Here is my checker-play question.  Suppose I have one man on the 24
point, and the other 14 in my inner table.  My opponent has 3 on
his/her 2 point and no other checkers.

Before my opponent rolls, I am given the privilege of arranging my 14
inner-board checkers however I like, with the only stipulation being
that these 14 checkers must remain in my inner board.  How should I
arrange them?  Should I maintain a closed board or should I leave blots
on my own low points in the hope of recirculating?

To win this game you need to get both blots, so having a closed board makes
it much more difficult.  You usually need to recirculate a blot or two to
get the second checker.  I'd want a prime from the 3 to the 8 point and
some blots on the ace and deuce.  If they MUST be all in the inner board,
then just close the board, put the spares up high and hope to roll two aces
right away to get both blots.

I think the redoubling point is when the opponent still has two checkers on
the roof, you open up your 6 point with 3 or 4 checkers now borne off, and
he fans with both checkers again.  It's a pretty big pass there.  If he
gets one in, then you still don't have a double.  This is a position that
tends to go from no redouble/take to redouble/pass with no redouble/take in
