You need to find a couple of pairs to place 1 in r6c5

Check column 7. Entries 3, 5 and 9 are excluded from two cells, so those cells must contain the pair (46). Bearing that in mind, check row 6. You will find a (24) pair which leaves only one cell in that row open to 1.

Quite a good puzzle if you don’t use pencil marks!
