About the Siesta Variation

The Siesta Variation, 5...f5, meets White's c3 with an immediate blow against e4, made possible because c3 now blocks the knight from supporting that pawn. The line covered by ECO C74 is 6. exf5 Bxf5, followed by 7. d4 or 7. O-O, when Black's bishop is active and the f-file is half-open. Online, 6. d3, keeping the center intact, is played slightly more often. The play is sharp, and engines rate it roughly balanced.
