Hi guys,

Today I completely redesigned the Endgame Lessons section of my chess app to make it more educational and closer to a real chess course.

Previously, the lessons contained basic positions and short explanations. I upgraded the system so that each lesson now focuses on teaching the actual endgame concept in greater depth. I rewrote the explanations to be significantly longer and more detailed, covering not only what the concept is but also why it matters, how it is used in practical games, and when players should apply it.

I also improved the board visualization. Instead of using generic markers, important instructional squares are now highlighted directly on the board using colored squares. This makes it easier to connect the written explanation to the position being displayed.

The lessons now include:

More realistic endgame example positions
Detailed educational explanations
Learning objectives for each topic
Highlighted critical squares on the board
Practical applications showing when the concept is used in real games
Reflection questions that encourage deeper understanding

Topics currently covered include:

Opposition
Key Squares
Lucena Position
Philidor Defense
Triangulation

More to be added soon…
