I'm printing off the book you linked to, many thanks to you Bill.

I was indeed looking for material, and not too much of it, that I could print off and play through. It's easy enough to find sgf collections, but I just cannot help zoning out when playing through games online.

Are there are any sources of lower-handicap games, please?

1) Pro-on-pro action (to see how to use handicap stones)

2) Pro-on-ama (to see how to play against handicap stones)

I like Kage's Secret Chronicles of Handicap Go very much. It is even more chatty than his Lessons in the Fundamentals, but despite this there are some truly nice advices to take away from it.
I also have good memories of Pro Pro Handicap Go but I only read it quickly a long time ago (and it was stolen from the club's library not long after so I've never given it a reread).

Vol. 2 of How to Play Against the Stronger Player consists of commented handicap games (4 to 9 stones if I remember well). It is been a long time but I remember that it was a nice read. There are at least two games for each handicap, one played well by the amateur, the other badly.

I've already enjoyed some of the 9-stone games. Wasn't able to follow the scores very far because the print quality was hard to read, but I picked up some interesting patterns all the same, and it also made me think, which was exactly what I wanted.

I'm aware of Kageyama's Chronicles - but the trouble is that it's only available for insane asking prices on Amazon.

Can you please give links to the other books if they're on sale somewhere?
