;W[dq]
;B[cc]C[Lukas (black) follows the new trend of early san-san's, which suits his playing style very much.]
;W[od]C[Cornel (white) answers with an unusual move - tenuki. ]

;B[qn]C[The upper right corner joseki used to be played often in the past before the AI. Nowadays, we can rarely see it anymore, because high approach (P16) is not used that much anymore.]
;W[ec]
;B[df]
;W[id]C[Probably black's position is a tiny bit better, but the game is still long.]

;B[sb]C[It is normal to make this exchanges: Black is alive in the corner and white gets good influence. But could white do something else instead of Q16?]

;B[ck]
;W[ej]
;B[bq]
;W[gp]
;B[hc]C[This is most likely the biggest turning point in the game. A move arround F8 area is very important for both players right now. Black made a mistake by not playing there. Also, it is not easy for white to protect the H17 weakness in an efficient way, if black does not play there right now.]
