Multiple Valid Strategies
| Move | Eval | Style / Strategic Idea |
|---|---|---|
| d4 | +0.93 | Classical Dominance: Direct control of e5 and c5. |
| c4 | +0.82 | English Setup: Clamping down on d5 for a long-term squeeze. |
Different paths, same destination: While d4 is the most principled and aggressive way to exploit Black's passivity, c4 is a sophisticated alternative that prepares a "Maroczy Bind" structure. Both moves are objectively superior to the common human mistake Bc4, which allows Black to equalize easily.

What Made This Move Good
You correctly saw: That Black has spent two tempi on non-developing moves. You didn't fall for the "automatic" development of the Bishop to c4; instead, you struck the center while Black was unprepared to contest it.
📚 Takeaway: When your opponent plays slow moves on the wings, the best response is almost always to open the center! Trust your intuition—you found the engine's top choice.
