Day 1 · Week 1: Your games, honestly

Today: 20 minutes, 40 if you have them. Rule 1, their move first: before every move, name what their last move attacks and what it left undefended.

Core (20 min)

Read the deep dive (15 min)

Deep dive 01: Your games, honestly is this week's idea. Read it and solve the positions in it.

Two warm-up positions

Every position below comes from one of your own games. Look at the highlighted last move first.

Post-mortem (5 min)
