    Pyv:
    After black R18, usually white answers S18 (which is fine), but sometimes white answers Q17, which leads to an incorrect answer after this sequence: bR18, wQ17, bS19. However after wP19, bS17 should be correct?
    caranthir:
    I agree. Actually, black does not even need to continue after w P19; white already died in gote. I added your move.

    S19 shouldn'T be incorrect after R18, Q17?
