Re: Getting back into go after 18 years
Ahh, I get it now. That's an idea I haven't thought about much, and I agree now. Thanks for being patient with me.

Re: Getting back into go after 18 years
Those 2 diagrams are a bit misleading though because in the first it is white sente and in the second black has sente. So how about comparing these?
What next for white do you fear in the 2nd? This? Next a for black? k6 is more interesting later now that black got the turn which makes up for the slightly slow feeling I get.
Interesting position

Re: Getting back into go after 18 years
In this case white has a good configuration on the left side.
is already in a low efficiency position. Black is not thick in bottom left after so many stones invested, this is troublesome. For example, black bottom left does still F4 weakness, with a little prep(white can't do this right now) white could use this to move out the two white stone and the four black stone would be cut off and fight next to the thick white group. Also
can simply go to bottom-left 3-3, if black covers from bottom then it's very low efficiency in bottom for black. If black covers from left-side because of the high position of 
and thickness of white center group, it's hard to build up an area efficiently on the left. Or white could G6 before D6 try to shut black in completely and aim to build a huge area with a stone around K12. Lots of good options for white.
In any case, fighting on bottom half of the board is going to make white thick center group efficient. It's best option to avoid any fight near that group and reduce its potential from afar.
Edit: Actually black is already in very awkward position when
goes to C3 directly.-

Re: Getting back into go after 18 years
I asked Jeff Chang 6d about this position. He said tenuki was a no-no, cut was a compromise, but acceptable for cashing in a lot of territory but does make it easier for white too, but he prefers to attack the group as a whole:

Attack whole group is certainly better than cutting directly
. But white wouldn't just connect 2 stones and be heavier. No doubt white will fight back with 
and then jump into center with 
(white should just into the center instead of J6 anyway), black 3 stones are bit heavy now. White 2 stones are light because of bottom-left 3-3 if black still wants to cut (and white G5 counter-attack is possible if white is settled in the center). If black keeps fighting in the center there probably will be a white wall in center-right side and white Q10 is now a good move(and build up an area in center-right of the board). And black is also risking white connecting those 2 stones back and attacking black in center if white easily settles in center. All these are still better than cutting directly but I still consider these to be helping white to play. White should welcome a fight in the center because black is moving against more white stones in the center and away from most black stones. Also blacking defending bottom corners is not simple tenuki, it's a method to reducing white center group's influence and a very much correlated move in the bottom half of the board. A tenuki would be a move in the top half of the board.
