SmallChess and it’s related apps are designed and developed by Ted Wong. Ted is a quantitative developer specialised in statistical modelling.
Are you curious how SmallChess looked like when it just started? It’s here. It worked but it wasn’t very good. It took me two years to reach a level that I was confident that it would work for everyone.
