The Czech Defense: Bc4 — How to Play Black
The Czech Defense (1.e4 d6 2.d4 Nf6 3.Nc3 c6) is a solid, no-nonsense way to meet 1.e4. After 4.Bc4, you strike back in the centre with 4...d5, reaching a balanced position that has been tested over 5,300 times in online play. The engine rates this -0.09, a dead-level edge for neither side — meaning you stand completely equal here. No tricks, no dubious gambits: just clear, principled chess. The drill below lets you practise the critical lines and see how to handle White's most common replies.

After White develops the bishop to c4, Black's central challenge 4...d5 is the whole idea of this variation. You immediately dispute White's space advantage in the centre, attacking the pawn on e4 and the bishop on c4 at the same time. White has to react, and the statistics show that this position leads to highly balanced play: across 5,336 games, White wins 48.5%, draws 4.1%, and Black wins 47.4%. That's as close to a coin-flip as you'll find in an opening. Your task is simple: know how to follow up after White's best reply, and avoid the common ways to go wrong.
The Engine's Preferred Path
Stockfish's top choice here is exd5, and it's easy to see why. After 5.exd5 cxd5 6.Bb5+ Bd7, White maintains a slight tension while Black has developed and traded off the central pawns cleanly. The engine evaluation stays at -0.09 — still dead equal. This is the line you'll face in the vast majority of games (4,655 out of 5,336). Notice how Black simply recaptures with the c-pawn, then answers the check by putting the bishop on d7. No fear, no complications: just straightforward development and equality.
Three Ways White Can Go Wrong
The Czech Defense: Bc4 is a great opening for Black partly because White has several tempting but flawed alternatives. Here are the mistakes to look out for from your opponent's side of the board. If White plays 5.e5, that is a mistake that loses roughly 1.1 pawns — White's best move would have been Bd3 instead. If White tries 5.Be2 (played only 6 times), that's an inaccuracy costing about 0.9 pawns; again, exd5 was better. And 5.Bxd5 is a real blunder: it loses about 2.7 pawns, as White gives up the bishop for no compensation. In all three cases, you emerge with a clear advantage. Keep your eyes open — many opponents will hand you an edge.
How to Handle the Most-Played Alternatives
Besides 5.exd5, the most common move you'll see is 5.e5 (255 games), followed by 5.Bd3 (232 games) and 5.Bb3 (163 games). After 5.e5, White scores only 47.1% — you're already slightly better, so just retreat your knight and enjoy the extra space. Against 5.Bd3 (White scores 52.2%) and 5.Bb3 (White scores 54.6%), Black should stay solid; these moves don't challenge the ...d5 break as effectively as exd5 does. Notice that 5.Bd3 and 5.Bb3 give White better results than 5.e5 or 5.Be2, so you'll want to be especially prepared to face those. The key is recognising that after any move other than exd5, White has failed to equalise in the centre — and that gives you a small but real edge.
