"Russian tournament" sets have similarities to Staunton sets, but are a type in itself. Characteristic are the finials, often in opposite colour, on the Kings and Queens, which are also very similar in shape, the Bishops without incision, fat pawns and wide bases. You don't see religious features in Russian sets.
