|16.e1717.d1718.b20 - cosmo was winning the corner battle. That makes it interesting that TwixtBot decided on |15.i14 instead of a clear corner battle win like |15.e18, especially since |15.i14 doesn't reach the bottom edge. That had to have been in anticipation of an in-your-face block on k15 like 19.m15. But the human went off script.
