It's minor, but important difference. In game with strong players one ko threat can be difference between win or lose entire ko.

thx for your support logan. Your solution is my first variant. So now we have 6 posts on these problems. Not too bad compared to the 10 posts 5 years ago.

You recanted too quickly, logan!
The threat is important, but W's option to sac the tail is, imho opinion, way more important than a ko threat here or there. (Obviously this problem, like any problem with an option to ko or compromise, is very dependent on threats.)
In Cyclops' line, B has an extra threat if W wants to ko... and gote if he doesn't.

In these problems you should always look for the strongest resistance. It will be solution 99% of the time. (Exceptions can be when author says otherwise & whole board problems.) Since the rest of the board is invisible then you can consider other factors as ceteris paribus and ignore them. So in this instance, White's strongest resistance is ko.

I think the convention is that you look for the most stubborn resistance to make sure that you can refute all lines (and often the most stubborn resistance has the most interesting suji), but you certainly don't play out an inferior line because it gives you a better position in the most stubborn resistance. Connecting in sente, rather than in gote, is worth gobs and gobs of points.
