Possibility  

Dieter: @ . The four marked points are references. But White loses the points marked a

Sente  

JoelR: To beat a dead horse, and are sente.

Better  

Now White makes the points marked a, and the points b are left for later. This result is better.

Bill: connects.

Even better  

Bill: Without doing much analysis, this seems even better than the Better diagram.
