What amateurs play and what strong players play
Among strong players, the most repeated line is 2.d42…d53.e53…f54.h44…h55.d35…xd3. At your level opponents spread out more: 2.d4 comes in 4 in 10 games, against 7 in 10 among players rated 2200 or more, and 2.f3 in 32 in 100. After 2…d5, 3.e5 shows up in 49 in 100 games at your level. After 3…f5, expect 4.f3 most often, in 35 in 100, then 4.d3, in 21. 4.h4, the strong players' favourite, appears in fewer than 5 in 100.

The plan, from masters' games
The strong players' line, 2.d42…d53.e53…f54.h44…h55.d35…xd3, does two things in a set order. First, it gets your light-squared bishop out before a pawn on e6 shuts it in. Then it goes after d4, the base of the d4–e5 chain, with your c-pawn.
1…c6 develops nothing. It prepares 2…d5, so the pawn that confronts e4 arrives already protected. With 3.e5 your opponent gains space, but the chain is now fixed and e5 has a single defender, the pawn on d4. That pawn is what you will attack.
That is why 3…f5 comes before you move the e-pawn: with a pawn on e6, the c8 bishop would be stuck behind d5 and e6. Outside the chain, though, the bishop becomes a target for pawns. 4.h4 prepares a push to g4, which would hit it. 4…h5 stops that, because g4 is now covered by your h5 pawn and by the bishop itself. Then 5.d3 attacks the bishop, which has no defender on f5, and 5…xd3 trades it off. Your opponent loses their light-squared bishop, and you get rid of the one the chain was going to bury.
With the bishop sorted, it is the c-pawn's turn. It already went to c6, and now it moves again, to c5, to hit d4: if d4 falls or gets traded, e5 loses its support. This is the most common plan in the structure: 6 in 10 strong online players choose it, and 1 in 2 over-the-board players rated 2300 or more. You can play it straight away with 3…c5, before the bishop comes out, and at your level it works: with 3…c5 you score almost 53 in 100, and with 3…f5, almost 50. Hitting e5 with 3…f6 is worse, because the f-pawn no longer guards e6.
At your level this sequence breaks off early, since 4.h4 is rare. When it does come, the reply worth learning is 4…h5: 7 in 10 strong players choose it, but fewer than 3 in 10 players at your level. Without it, the pawn reaches g4 and your bishop has to retreat.

The mistakes that cost the most games
f6Inaccuracy
After 3.c3, 3…f6 lets the e-pawn advance with tempo: 4.e5 hits the knight, which goes back with 4…fd7, and after 5.d35…c5 the push 6.e6 hits f7 and the knight on d7. Best is 3…dxe4. It is an inaccuracy: you score 45 in 100 instead of 47, and at your level opponents often don't punish it.
12 in 100 play it in this position. It gives away 0.8 pawns of advantage. It scores 45.3%; dxe4 scores 47.2%.
e6Inaccuracy
Against 3.c3, 3…e6 shuts your c8 bishop in behind d5 and e6, the very thing the Caro-Kann is built to avoid. After 4.d34…dxe45.xe4, d4 is undefended, but if you grab it with 5…xd4, 6.f3 hits your queen and makes it move again. It is an inaccuracy: you score 46 in 100, against 47 with 3…dxe4.
11 in 100 play it in this position. It gives away 0.6 pawns of advantage. It scores 46.3%; dxe4 scores 47.2%.
f6Inaccuracy
3…f6 hits e5, but after 4.f3 the pawn has two defenders, d4 and the knight. And with the f7 pawn gone, only the c8 bishop covers e6, while your g8 knight loses the f6 square. It is an inaccuracy, but a costly one: you score 43 in 100 with it and almost 50 with 3…f5.
2 in 100 play it in this position. It gives away 0.8 pawns of advantage. It scores 43.3%; f5 scores 49.5%.
d4Inaccuracy
After 2.f32…d53.c3, 3…d4 hits the knight and grabs space, but the pawn drifts away from its support. 4.e2 steps aside and 5.c3 attacks d4; if you trade with 5…dxc3, then after 6.bxc3 the pawns on c3 and e4 control d4 and d5. Best is 3…g4. You score 48 in 100 instead of 51.
13 in 100 play it in this position. It gives away 0.8 pawns of advantage. It scores 48.2%; g4 scores 51.1%.
g4Mistake
After 2.f32…d53.d4, 3…g4 pins the f3 knight to the queen. 4.h3 puts the question and, after 4…xf35.xf3, your opponent keeps both bishops. Without your light-squared bishop, 6.b3 hits b7 and you have to cover it with 6…c7. Best is 3…dxe4, but at your level opponents don't punish this: you score 54 in 100.
26 in 100 play it in this position. It gives away 1.1 pawns of advantage. It scores 54.1%; dxe4 scores 53.4%.
f6Inaccuracy
After 2.c32…d53.exd5, the natural move is 3…cxd5, which keeps a pawn on d5. With 3…f6, 4.dxc6 takes the c6 pawn too and, after 4…xc6, you have no c- or d-pawn left while your opponent takes the centre with 6.d4. You score 48 in 100 instead of 52.
5 in 100 play it in this position. It gives away 0.8 pawns of advantage. It scores 48.5%; cxd5 scores 52.0%.

Over the board, 2300+ · the 6 most frequent combinations
You answer 1.e4 with 1…c6 so that 2…d5 comes with a protected pawn. It shows up in 5 in 100 games between 900 and 1700, and more often as ratings rise: 4 in 100 at 900 to 1100, 6 in 100 at 1500 to 1700. In every one of those bands you score about 50 in 100.
What is the main pawn idea in the Caro-Kann?
Hit the base of your opponent's chain. When your opponent plays 3.e5, the pawn on e5 leans on d4 alone. Your c-pawn goes to c5 and attacks d4: if d4 goes, e5 loses its support. 6 in 10 strong online players pick that plan in this structure.
What should you do with your bishop in the Caro-Kann?
Get it out before the e-pawn moves. After 3.e5, 3…f5 puts the bishop outside the chain before a pawn on e6 closes it in behind d5. If 4.h4 prepares g4 to chase it, answer 4…h5. When 5.d3 offers a trade, 5…xd3 accepts it.
Is the Caro-Kann good for beginners?
It holds up at every level. Between 900 and 1100 you score 50 in 100 with it, the same as between 1500 and 1700. The plan is short to state: protect d5 with c6, get the light-squared bishop out before playing e6, then attack d4 with the c-pawn. Watch out for 3.d2, where you score only 44 in 100.
