(;CA[UTF-8]LT[]RR[Normal]GM[1]NW[20]C[This was a weird game for Brown Stone. There was not much counting because everything was focused in the Apex.

When White made what Black thought as a small move at B, Black made a big reduction with C. White made another small move at D that allowed Black to approach at E. After the slide of Black F, Black aimed at C17 to counter the value of White D. When White invaded with G, Black thought cutting White off with H was natural. Black was prepared to fight with Black H. Black made a big msitake connecting at I that allowed to make one eye with J. Black should have played at J. The cut of White I does not work because of the kosumi on the second line. White's biggest mistake, might have been taking profit with L after invading with K. Black built a powerful wall that helped Black in killing the White Apex group. The double hane of Black M was also vital to Black's big capture.Brown Stone managed to counter what seemed to be Mirror Go by playing tengen. Despite some slips, Brwnstn was able to use proper direction of play, ignore small moves, play bigger and more immediate moves, and use enough time and variations to read.
