Editorial interest 86/100 Selection signal · not a rating of the site

A source-cited reconstruction of Tamerlane's 14th-century chess variant, playable against a bot or other people across web, desktop, and Android.

Landing page captured for the 2026-09-06 issue.

Field notes

The reconstruction models an 11×10 board with two additional citadel cells and preserves pawn identities through promotion, including the Pawn of Kings and a three-stage Pawn of Pawns ladder. Its bot is described as using alpha-beta search with a transposition table, iterative deepening, and quiescence across five difficulty levels. The project also presents a shared C# rules engine behind browser, desktop, and Android clients, with local analysis and a learn mode explaining departures from FIDE chess.
