;B[fo]C[This AI-inspired cosmic style move is a new favourite of mine. Prior to this game, I watched Alexandre Dinerchtein 3p's review of Stanislaw Frejlak 7d's game from round 5 where they played this move twice. Stanislaw ultimately lost that game, but I thought it was worth a test drive!

White has a number of possible responses, but in all cases black is going to limit white's potential significantly.]N[Aside]LB[dn:D][fp:B][hp:C][eq:A]

The game is very close and how much of this area white can convert into territory will be critical. What is black's best continuation on the right?]LB[og:3][ql:1][ro:2]

This is somewhat unsatisfactory: white has been able to surround some solid territory and the black stones on the outside are filling dame.

There must be a better way to take advantage of the weaknesses in white's shape...]

White has two promising candidates to consider here.]LB[oe:B][nf:A]

Unlike in the game variation, all of the stones black has played are useful - it's much better!

Note that white cannot prevent black from pushing through at 1. If white takes this point instead of connecting then black will play on the outside at 2 and the whole white group is in danger.]LB[nf:A][pf:1][oh:2]

What I've presented is one of the simpler AI variations where the right side territory got split between the two players.

The game is still extremely close.]
