Zoltan: I just don't seem to get to a correct answer following the f18-e17-f17-f16-e16-g18-f15 path. There is one right? :D
posetcay: The sequence shown in the tsumego was obselete, an outdated relic of ancient times. Fixed the tsumego according to modern knowledge. Sometimes simple is the best.
StephaneLamy: This yose problem with just 6 stones on the board is very strange.
After F2E3F3F4 probably the next best move is completely dependent on the global situation (for instance G2 could be the best follow up in some situations, but is marked "incorrect")
Ivan Detkov: It is not really yose. This move is played in the middle game because of its huge value. This task is bad.
