If you play @ , I'll play the other one.
I have no idea if playing inside like this will help me out in the long run ... I'm hoping it pokes some extra liberties off for capturing, but ??

I feel lucky. I was slightly kicking myself for trying to be too clever (playing at "a" and allowing at doesn't work, so I figured I'd create an opportunity to rip White off). Although that's a fairly normal Go sequence, the red stone really changes the capture dynamic, and playing one to the left seems more severe, as it creates a snapback using Black's capture (with a red stone) to capture Black. There are some subtle changes in the logic of multi-group captures...

It's worth bearing in mind here that White needs to fill in internal liberties to capture the lower right Black stones. And is necessary - if Black plays there, he lives inside (!!) as White can't atari due to his own shortage of liberties, giving Black two complete eyes.

possibly b also. 
@ 
, I'll play the other one.
at 
doesn't work, so I figured I'd create an opportunity to rip White off). Although that's a fairly normal Go sequence, the red stone really changes the capture dynamic, and playing one to the left seems more severe, as it creates a snapback using Black's capture (with a red stone) to capture Black. There are some subtle changes in the logic of multi-group captures...
is necessary - if Black plays there, he lives inside (!!) as White can't atari due to his own shortage of liberties, giving Black two complete eyes.
