What to do here

The Stafford trades a pawn for time and open lines against f2. After 4. you have doubled c-pawns, but the d7 pawn is out of the way: your c8 bishop sees all the way to h3 and your queen looks down the d-file to d2. That's why almost everyone takes back with the d-pawn: keeps both lines shut, and your opponent's score rises to 62 of 100. The strong-player line is 5. 6. 7., followed by or .

Your pieces point at f2. hits it along the diagonal toward g1, and your f6 knight wants to reach g4 to hit it a second time. Then f2 has two attackers and only the king to defend it. Your opponent's moves work against that. 5. props up e4 and frees the c1 bishop, and 6. covers g4. Hence : the pawn guards g4, and if the e2 bishop ever takes a knight there, you recapture with that pawn and your h8 rook sees down the h-file to h2. Strong players choose in 89 of 100 games, though right away is slightly more accurate.

7. prepares d4, which would hit your c5 bishop. This is where your level and the top split apart: strong players answer in 49 of 100 games, while the public plays it in only 10. You pull the bishop back before the pawn arrives and keep it on the same diagonal toward f2. The other half of strong players go , putting two pieces on f2 with only the king to guard it.

If your opponent steps away from 5., the idea stays the same. Against 5., which covers e4 with the knight, your opponent scores 43 of 100. Against 5., which kicks your knight, send it to d5 with : no white pawn attacks it there.
