Most players learn to play 3-1, 4-2, 5,3 ,6-1 & 6-5. Against a weaker player in money game is it possible to play 62U or 62D to complicate the game.

And in the next 30 minutes of their careers, they learn a few more things? I suppose, if we're talking about extremely weak opposition, you "can" do just about anything you want.

But I'm not sure why you think 6-2 24/16 or 13/5 instead of splitting would be more complicating. It is because (as your comment about the obvious opening plays seems to suggest) that you a weak player might auto-play and make a point instead of hitting, when hitting is better?

For example, after 24/16 the very weak player might play 3-1 8/5 6/5 instead of 13/9* ?

In that error-error sequence, Gnubg 4-ply says 8/5 6/5 is a -0.024 error. But your equity is -0.050 (if opponent plays 13/9*, your equity is -0.074).

Compare that to 6-2 24/18 13/11 ... 3-1 8/5 6/5. Now according to Gnubg 4-ply your equity is +0.0220 (if opponent incorrectly hits, it's +0.065).

So, with that sequence of rolls, even if you were sure your opponent would err, you're better off playing your opening move correctly.

About opening 4-3, seems to me that 13/10 13/9 (which the bots barely favor with equal and expert opposition), ought to be even better than splitting against a very weak opponent, considering of course not just the next roll, but the types of strategic errors that weak players make, for instance: holding on to the 24 point for dear life, not correctly deciding if and when to split, and misjudging prime vs. prime positions.

My feeling is that it is very easy to overrate and overthink the value of making suboptimal plays against suboptimal players. The bots do just fine against such opposition, without ever giving that strategy a single thought.
