I've always played 24/21 13/9. Hitting on the 2pt has always looked too deep to me.

I haven't got a reliable computer at present to do a strong rollout, but here's an appetiser. 24/21 6/2* looks pretty good now that I've given it some thought (all those damn 70's bg books I've read makes plays like 24/21 6/2* hard for me to find), but nonetheless, 24/21 13/9 is doing remarkably well at this stage of my rollout.

Looks like it might be worth a strong rollout to me.

The score (after 0 games) is: White$ 0, Blue$ 0

Move number 6: Blue$ to play 43

White$162

Blue$167
