The keima helps develop the lower side

;W[qj];B[jq]
C[…Black 1 is the standard move. White extends to 2 and Black extends to 3.
Black’s main prospect is to develop the shimari towards the upper side. The white star point (hoshi) stone in the lower left corner has good prospects on both sides, and Black’s extension 3 takes more away from White than White’s extension 2 takes from Black. So this result is better for Black than for White.]

(;B[qo]
TE[1]C[Correct answer
The shimari secures territory
This move is also good, since Black makes quite a decent profit. White then plays A or B (see problems 97-98).]

BM[1]C[Wrong answer
The outside tsuke gives neither territory nor influence
Black 1 is bad here. White continues at A or B (see problems 101-102). Black will probably lose points in the corner, and it is not yet clear whether outside influence will make up for them.]

(;B[ql]
BM[1]C[Wrong answer
The hasami leaves a low position on the right side
The hasami 1 looks unnecessary, since Black already has the stone /\\ on the third line. Black cannot build a large moyo on the right side. White continues at A or B (see problems 103-104).]
