Play New Chessmaster, The Online

I picked up The New Chessmaster for the original Game Boy back when it was new. It was developed by Nintendo and released in 1990, a time when the handheld was full of puzzle and strategy games. This one fit right in, offering a portable version of chess without any grand claims.

You control the chess pieces in the standard way, moving them across the board to capture your opponent's king. The game includes a few distinct features, like a teaching mode that explains moves for beginners and a puzzle mode where you must solve a checkmate in one move. The pacing is methodical, as you'd expect from chess, and the computer opponent provides a decent challenge on higher difficulty settings. It feels like having a quiet, competent chess partner in your pocket.
