What to do here
The line strong players follow is 4.c34…f65.d35…d66.O-O6…a57.e17…O-O. The goal is to hold your e5 pawn, keep the c5 bishop on its diagonal toward f2, and castle before White gets a supported pawn to d4. What you end up with is a closed structure: your pawns on e5 and d6 against White's on e4, d3 and c3.
4…f6 comes first because it hits e4, and at that moment no white piece guards it. White usually picks one of two roads: 5.d4, which shows up in 55 of every 100 games at your level and opens the center, or 5.d3, which protects the pawn and is the choice in 79 of every 100 over-the-board games above 2300.
After 5.d3, 5…d6 gives e5 a second defender next to the c6 knight and opens the diagonal for your c8 bishop. With White's pawn already on c3, another pawn on b4 would attack your c5 bishop and kick it with gain of time. That is why 6…a5 comes before castling: with your pawn on a5, any pawn that reaches b4 can be taken. Then 7.e1 adds the rook to the defense of e4, which only the d3 pawn was covering, and prepares the push to d4. Your 7…O-O gets the king safe before that break opens the e-file.
This is where your level and the strong players part ways most clearly. After 6.O-O, players at your level go 6…g4 in 45 of every 100 games; strong players pick it in only 5. They prefer 6…a5, which looks after the c5 bishop first and leaves the other bishop for later. Keep in mind, too, that a bishop on g4 can be hit by a white pawn on h3.
If you meet 5.d4 instead of 5.d3, trade with 5…exd4 and, after 6.cxd4, check with 6…b4+: if White blocks with 7.c3, that knight is pinned to its king and no longer guards e4.

The mistakes that cost the most games
h6Mistake
After 4.c3, 4…h6 spends the tempo that 4…f6 needed and leaves e4 alone. White goes 5.b4, hitting your bishop; after 5…d6 that bishop blocks your d7 pawn, and 6.O-O6…ge77.d4 hands White the center. At your level 7 in 100 play it, and you score 45 points per 100 against 46 with 4…f6: hardly anyone punishes it.
7 in 100 play it in this position. It gives away 1.7 pawns of advantage. It scores 45.2%; f6 scores 46.0%.
4.g5 aims knight and bishop at f7, but the knight has no defender: 4…xg5 just wins it. With 4…h6 you guard f7 and pass up a free piece, and after 5.f3 the knight walks home unharmed. Facing 4.g5, 19 in 100 players at your level choose it; you score 72 points per 100 with 4…xg5 and 58 with 4…h6.
19 in 100 play it in this position. It gives away 7.1 pawns of advantage. It scores 58.2%; xg5 scores 71.9%.
h6Inaccuracy
Against 4.O-O, 4…h6 is an inaccuracy, not a serious mistake. It delays 4…f6 and lets White build the center: 5.c35…b66.d46…exd47.cxd4 leaves pawns on e4 and d4. About 8 in 100 play it; your score drops by less than 1 point per 100, so at your level it almost never gets punished.
8 in 100 play it in this position. It gives away 0.9 pawns of advantage. It scores 48.8%; f6 scores 49.5%.
g4Mistake
After 4.d34…f65.c3, 5…g4 hits f2 with knight and bishop, but the answer is 6.d4, which attacks your bishop and cuts its diagonal to f2. After 6…exd47.cxd47…b6, 8.g5 hits your queen, and 8…f6 takes the square your knight would retreat to. You score almost the same as with 5…O-O: the punishment rarely comes.
7 in 100 play it in this position. It gives away 2.3 pawns of advantage. It scores 46.7%; O-O scores 47.0%.
After 4.d34…f65.c3, 5…g4 goes after f2 with knight and bishop, but 6.O-O covers it with the rook and your knight heads back with 6…f6: two tempi gone while White develops with 7.e3. It is an inaccuracy, yet it shows: you score 43 points per 100 with it and 49 with 5…a6.
7 in 100 play it in this position. It gives away 0.7 pawns of advantage. It scores 43.3%; a6 scores 49.0%.
a6Mistake
After 4.c3, 4…a6 clears a7 for the bishop but puts no pressure on e4. White plays 5.d4 unopposed: 5…exd46.cxd46…a77.c3 leaves pawns on e4 and d4 with the knight already out. Only 3 in 100 choose it, and you score about the same as with 4…f6, so at your level it rarely matters.
3 in 100 play it in this position. It gives away 1.2 pawns of advantage. It scores 45.8%; f6 scores 46.0%.
It is the Italian Game when you meet 3.c4 with 3…c5, so each side has a bishop trained on the other's weak square, f7 and f2. The main line starts with 4.c3, preparing a pawn on d4. At your level it comes up in 5 of every 1000 games, and results are close to even: you take a little over half the points.
What are the main Giuoco Piano variations?
The big split comes after 4.c34…f6. 5.d4 opens the center and leads to Greco's Attack after 5…exd46.cxd46…b4+7.c3, while 5.d3 keeps things closed. At your level 5.d4 turns up in 55 of every 100 games; over the board above 2300, 5.d3 is the choice in 79. White can also hold off on 4.c3 and play 4.d3 or 4.O-O.
How is the Giuoco Piano different from the Pianissimo?
Pianissimo is the name for slow lines such as 4.d3, which keeps e4 protected and doesn't try to open the center. The classical Giuoco Piano is 4.c3, aiming for a pawn on d4. At your level each shows up in 25 of every 100 games; strong players prefer 4.c3, though over the board 79 in 100 follow 4…f6 with 5.d3.
Giuoco Piano or Evans Gambit: what is the difference?
The Evans is 4.b4: White offers a pawn that your c5 bishop can take, since nothing guards b4. In the Giuoco Piano proper, White plays 4.c3 and keeps the pawn. At your level 4.b4 appears in 4 of every 100 games after 3…c5, and you score 45 points per 100 against it. Strong players online pick it in 10 of every 100.
