Here is a diagram showing the focus of this file.
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.

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' \(P3\). It proved better and has taken over in the autumn in 2001.
Black 'c' \(C3\) is a little old fashioned but somewhat reasonable. 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.

White 'c' \(R11\) is not acceptable because it allows black's making the larger extention at 'b'. Other plays are secondary options.
