Opening 64: Three choices

There is greater choice in the opening 6-4. There are three reasonable
plays. I have seen strong computer programs choose each of the three.
You can run with 24/14. Tries to escape a back checker and build the
outer table. Most of the time you get away with it and have a small
plus, but when you are hit you are suddenly a substantial underdog.
These conditions indicate that running is a good play if you need to
have a high overall chance of winning, and do not care about winning
or losing a gammon. Say at double match point.
You can split with 24/18 13/9. This tries to build, to make an advanced
anchor, and to escape a man. The man on the 18-point looks exposed, but
if it is hit there with a blot, then there are 16 return shots. In fact,
the opponent can actually expect to lose ground in the race after he
hits with a blot! This move creates a lot of tricky counterplay. It is
an excellent move if you are the stronger player. (I like to think
I am a stronger player, so this is my move!)
You can point with 8/2 6/2. This solid move leaves no shots, and it
has tactical benefits. For instance: the opponent cannot split his
back men with an ace, so he has to play aces with 19/20, leaving a
shot when you have made an extra inner-board point. The problem
with pointing is that you lose a lot of equity in the priming game,
since it is hard to build a prime that includes the deuce point.
On the other hand, you strengthen your blitzing game. It follows
that this move is excellent when winning a gammon is important, say
if you are down by a lot in the match.
