posetcay: I feel like the variations where black lives with just 2 points instead of 5,5 is too inferior to be accepted as correct in an advanced collection, I can restore them as correct if the majority disagrees.
Tom1980: After Q15, Q14, T16, T15, Q19, T17, S18, S19, R19 is shown as the only move. But doesn’t R18 work just as well? The same move works in a number of the other variations too.
Ok, I added a hint.
