Why 
c4 ?⚠️ c4? — mistake
EVAL:
[███░░░░░░░]-1.10+0.86 → -1.10 (Loss: -1.96)
💡 Problem with c4:
This move ignores the pressure on the f3 and creates a massive hole on the dark squares. It allows Black to develop with a devastating tempo via 
b4+, forcing the White King into discomfort or awkward trades.

📚 Lesson: When your piece is under attack (like f3), prioritize resolving that tension before creating new weaknesses in your own camp.
