Modern chess theory was slow in developing. After the new moves of the pieces, players spent their time playing gambits, and trying to mate each other. The games of Gioacchino Greco (1600– ~1634) clearly show this. The first ideas as to how to win indirectly, 'positionally', started with Philidor. Modern chess has a lot of indirect manoeuvering of a kind the old Arabic players would have understood. They could not attack directly, because their Alfil and Firzān (our bishop and queen) had such limited moves.
