;B[nq]C[active play, this may help attack C4, but hurts the top right, so hard to say. It didn't pick this vs Park in game 24

you could also say this is a probe, inviting W to pincer]

;W[mb]C[if you were always going to disconnect, you lost nothing, but you lost something if you wanted to pressure on the outside and let W connect. Clearly B thinks that W is still too weak to let connect up (mostly not about the 5 points), especially when B is weak.]

B just slowly makes eyes

The bottom left W group also doesn't have eyes and the bottom right corner is open, so B should have a good lead with the centre potential already]
