Lee Sedol 9p once said that this could be Park's weakness, and that he needs to develop a his own style in order to become #1.Fan Tingyu's style of play is similar to Park's, but Fan's style of play is thicker and more solid, and more defensive too. Park's style is more flexible and he's more of an all rounder. Anyway, let's have a look at game 4 from the 7th Ing Cup final.]RE[B+5.00];B[qd]C[Fan Tingyu plays black. ];W[pp];B[dd];W[cp];B[ep];W[eq]C[Park chose the most common joseki.

The official result was that black won by 5 points after Park twice paid 2 points to ‘buy’ more time (Ing timing) and Fan also purchased one lot of extra time.It was a very exciting game, especially after black tried to save his stones in the left center. Fan's second half of the game was very impressive. His reading during the battle in the center was accurate, and his endgame was perfect. On the other hand, Park managed the first half of the game very well, after taking the lead at an early stage. His sacrifice strategy and positional judgment were amazing, and he maintained the lead afterwards. However, he made a simple mistake at the end, and it cost him the game.I hope you'll enjoy this marvelous game more with this commentary, and please feel free to leave a comment if you have any questions.Thanks,Commented by An Younggil 8phttp://gogameguru.com/])(;W[ml]LB[oi:B][oj:A]C[This move doesn't work for white, because of the exchange of A for B.];B[ll];W[im];B[nk]TR[ml][nl]C[White can't save the marked stones.]))(;W[io]C[White would have won the game if white had peeped here. ](;B[in]C[If black answers here, ];W[kp]SQ[iq][lq]C[White can extend here to capture the marked stones.
