Deschiderea anti-chineză

White's small knight move defence at 'b' \(c6\) is the most usual way to respond black's approaching move. However , since it is amply proved black's advantage in the small chinese opening games, white needs any anti-plans. As is seen in this diagram, often black makes the approaching move first, leaving two empty corners. ]EV[Modern Game Insight]RO[The No.7 issue of the suite]PC[Nara, Japan]SO[Various internet and conventional go information servies - newspapers, monthly journals, books, and others.]US[nettwins@kcn.ne.jp \(Hajime Okada\)]CP[nettwins@kcn.ne.jp \(Hajime Okada\)]GC[Modern Game Insight Issue 7.

To prevent small chinse opening game white may play in the side, with 'a' \(H3\), 'b' \(J4\), 'c' \(O3\), 'd' \(O4\), or 'e' \(P4\). White 'c' \(O3\) and 'd' \(O4\), which are recommended by Go Seigen, were firstly used by devotees of his theory, such as, Rui Naiwei and O Rissei. Go has critcized 'e' and suggested 'c' and 'd', instead. Nevertheless, white 'e' has not been discarded by world champions as yet. It is one of the generally held views of Korean research that white pincer at 'b' is disadvantagous against black's counterpincer at 'f' \(L3\). However, this view is not always agreed among Japanese players.]LB[hq:a][ip:b][nq:c][np:d][op:e][kq:f] (;W[hq]C[Black's enclosure with 'a' or 'b' is the prior option. Black 'a' \(O3\) has been generally applied and there are many examples. However, the most current move of the top players is black 'b' \(P3\).

Black 'd' \(C6\) could be possible as well, while both black 'f' \(F5\) and 'g' \(D6\) are not acceptable in this position. There is nothing or very few examples for these. However, black 'e' \(C14\) followed by black 'd' is a interesting way. Black 'e' \(C14\) to 169: Kobayashi Koichi \(b\) - Chang Hao \(w\) at the 13th Tengen - Tianyuan.
