Weiqi Rapid Drill 800 Problems
Weiqi Rapid Drill 800 Problems 围棋快速练习 800 题 (Wei2 qi2 Kuai4 su4 Lian4 xi2 800 Ti2) is a 268 page book containing 800 problems published in April 2003 by Chengdu Shidai Publishing (成都时代出版社) with the ISBN 7-805480851-7/G.779
Each page consists of six problem diagrams. Solution diagrams are on the overleaf; one diagram per problem. The last page contains a rating table which indicates the reader's level or rank based upon number of problems solved correctly, ranging from 200+ correct answers being amateur 2 kyu to 700+ correct answers being amateur 3 dan.
The book can be found on eBay being offered by goplayer2006 (this is 震 主 Zhen Zhu - Go teacher on KGS known as hotdog).
To find the correct answer to some of the problems, the reader is required to take into account follow-up moves. For example in Problem 98, both a and b kill White, but one choice is better than the other because it leaves Black with better endgame.
