Behair: This is again very confusing: in other problems you claim that the correct endgame is where the profit is optimized, independently of sente/gote. Here you claim a best sequence for sente only, even when losing 3 points locally (best answer from local profit only is C17/C18 first, then K18/J18. This should be definitively clarified what you expect from us!!
d4rkm4tter: Difficult to clarify. What would you do? Maybe writing more hints. The rule of thumb is that a gote move has to be worth twice as much as a sente move to be better.
Zahard: Opening with K2 is superior in Points and ends in just the same gote/sente situation. I dont see any advantage in L2
d4rkm4tter: This problem is unclear when played out to the last point, so I removed a move from each sequence. Now it is clear that L1 ends in sente while K2 ends in gote.
I tweaked the problem a bit, there shouldn't be anymore sente/gote debates as J19 is now the best move unconditionally.
