Junior Chess

Junior Chess keeps the full rule set of real chess intact rather than simplifying the pieces or the board, what changes is the difficulty curve, adjustable AI strength lets a beginner actually finish games instead of getting overwhelmed by an opponent playing at full strength immediately.

Because the AI difficulty scales rather than staying fixed, moving up a level only after consistently winning at the current one tends to build real pattern-recognition skill instead of just memorizing one opponent's habits. Thinking a move or two ahead before committing, rather than reacting to whatever piece is currently under threat, is the habit that carries over most directly as difficulty increases. Checkers offers a simpler forced-trade strategy game if chess's full rule set feels like a lot to start with.
