I finally got your "crossing" technique and it's was very helpful in box 7!! The longer explanation a few days ago helped me integrate it into my solving and I'm getting faster...Thanks!!!
3:20 It looks as if my practice of cornermarking two or three cells in a column (not-quite Snyder notation) pays off here. 11:10 So did filling out the grid when I'm stuck. I found two triples in tandem, row 2 followed by column 6. 347 and 467 IIRC -- a bug that I hadn't encountered for a year at least in backtracking reappeared in full force, so I can't backtrack to check.
129 triple for column 4.. 129 in box 5, and 129 in row 1..
