Hitting on the 3-point is a must. Non-hitting plays simply allow White to play freely, and give him the initiative.
After hitting, the rollout shows 13/11 is a better 2 than 24/22 and I think this result is reasonable.
True, 24/22 tries a better anchor and White's 3's are duplicated, but White is not threatening much and Red would rather want to split to a better point for the anchoring purpose.
In spite of the rollout results, however, I still don't think playing the 2 with 13/11 is particularly productive.
A little positional gain produced by this play doesn't seem to compensate for the risk of giving White additional hitting 5-6's.
(Note that 6/3*/1* loses slightly fewer gammons than 13/11 6/3*)
The checker on the 3-point is still too deep to be effective as a blocking point anyway, so I would continue on to the ace-point.
Since Red doesn't have any particularly productive 2's to play, he might be better off keeping White busy for a roll.
