I agree with you Ema, yesterday's H puzzle was very messy. I found that a couple of box-line eliminations were needed quite early in the piece, starting with Col 3 if I recall.

Post your grid if your still stuck - we're here to help.

Cheers

To answer your question, there is a <567> Naked Triple in r8c136 that results in r8c2=4 ... and the eliminations r8c79<>5.
