This it is as far as I can get it (almost):

When I run the pointing pair algorithm, I see a pair of 5's in [R4C2] and [R4C3] that eliminates the other 5's in [R4C5] and [R4C6]. X-wing, Y-wing don't reveal anything new.
Is there a guru who can offer me a suggestion for a possible next move?
Are there puzzles where a "guess" is required, or should all puzzles be solvable with logic?
Thanks,
