PW[Kang Dongyun]PB[Chen Yaoye]WR[9p]BR[9p]DT[2013-12-3]EV[15th  Nogshim Cup]SO[gokifu.com]C[China decided to send out Chen for the sixth game of the Nongshim.
Chen has a winning record against Kang, but both are top players right now, so this will be a very exciting game.
China has longed to win the Nongshim against Korea since their defeat last year, so this will be a very important match as well.]RE[B+Resign]BC[cn]WC[kr]
