Hi guys, today I built a new Endgame Puzzles feature for my chess app called ChessHub.

It lets users practice real endgame positions from a puzzle database and actually play them out on a board instead of just looking at them. You can choose to play as White, Black, or let it auto assign your side, and the board flips depending on what you’re playing so it always feels correct.

I also added a full training system around it. It tracks your accuracy, keeps a streak of solved puzzles, and tells you when you get something right or wrong. There is also a hint option if you get stuck, and you can reveal the full solution line to learn the idea behind the position.

After each puzzle, you can instantly move to the next one or reset it, so it works like a continuous training mode instead of a one off puzzle viewer. After a lot of struggling by myself and some use of AI to resolve some major roadblocks I finally finished with this ————>

More feature coming soon…
