This page is intended as a collection of tesuji where people can learn various tesuji and connect them with names. While I have tried to stick with "standard" names, I have taken the liberty of renaming some tesuji which have Japanese names, and naming some unnamed ones. I find that an easy-to-remember name makes tesuji stick in my head better. This is mainly for my own review, but I'm posting it here in the hope that others might find it useful.
