Fischer Bc4

The Fischer–Sozin Attack, named after Bobby Fischer and Russian master Veniamin Sozin, who originated it in the 1930s.
The move that Fischer used was 6. Bc4. This Bishop sits on c4 and trys to cut across the board to attack black’s structure.
It will often be retreated to the b3 square to maintain its post.
