It doesn't threaten anything, nor does it really defend much territory. It does connect the stones, but black is not in danger. Any attack by white will merely strengthen those stones for black, which will then allow a deeper invasion into white's moyo on the left or bottom. I like a move at the marked spot for black.

White's group is in place as a spoiler, and black's move does not threaten that status.The marked stone is in danger, but it's not urgent. The adjacent stone is close, which mitigates the damage. It's frustrating and inefficient to play here now, and ultimately it's not many points at this time.Again, my eye is drawn to white's wide open corner. ];W[cm]WL[-546.8];B[no]BL[-1579.8]C[This is a slow move.
