The Sicilian Grand Prix Attack is a sharp, aggressive way to meet 1...c5 without diving into the endless theory of the Open Sicilian. But when Black answers 2.Nc3 Nc6 3.f4 with 3...e6, the game takes on a different character. You are playing White, and the position after 4.Nf3 is surprisingly balanced — Stockfish rates it -0.04, a dead-level game, meaning you are neither better nor worse. With 712,575 games played from here, White scores a healthy 48.6% win rate. Let's look at what Black usually tries and how you should respond.

Black has many choices here, but one stands out above the rest. The most-played move is 5...d5, appearing in 225,350 games — nearly a third of all encounters. White scores 47.4% from here, so you can expect a tough fight. The engine also approves of this move, as it challenges your centre immediately. Other common tries include 5...a6 (105,363 games, White scores 47.2%), 5...Nf6 (104,670 games, 48.5%), and 5...d6 (54,493 games, 51.5%). That last number should catch your eye — White actually scores above 50% against 5...d6. But be careful: the engine considers 5...d6 an inaccuracy that loses about 0.6 pawns, so your opponent should avoid it.
The Engine's Top Choice: Black's Best Reply
Stockfish's number one recommendation for Black is 4...Nh6 — an unusual-looking knight move that defends f7 and prepares... d5 or... Nf5. The engine's full line runs: 4...Nh6 5.d4 d5 6.Bb5. In this sequence, you push d4 to claim central space, Black responds with d5, and you develop your light-squared bishop to b5 with pressure. If Black doesn't play Nh6, other moves like 5...d5 are perfectly fine for you as White. Just remember that your main weapons in the Grand Prix Attack — the f4 pawn, Nf3, and Bc4 (or Bb5) ideas — still apply, even if the game is more positional than you might expect.
Your White Strategy: Key Ideas to Remember
With the evaluation dead level, your opening edge depends on understanding the typical plans. Against 5...d5, you can consider 6.exd5 exd5 7.Bb5 or 7.d4, keeping the game rich in possibilities. Against 5...a6, you might prepare Bc4 or Bd3, eyeing the kingside. Against 5...Nf6, be ready for transpositions to King's Indian or French-like structures. Your winning chances are a touch above Black (48.6% vs 48.1%), but draw rate is very low at 3.3% — so someone usually wins. Trust your attacking instincts from the Grand Prix setup, but stay flexible. The engine's evaluation of -0.04 means small inaccuracies matter more than ever, so practice these common responses with the engine's line as your anchor.
