Why e7 ?❌ e7?? — blunder
EVAL:
[██████████]M5+12.32 → M5 (Loss: -87.63)
💡 Problem with e7:
Stepping the e8 into the center allows the White 
a4 to deliver a devastating check on d7. This forces the King into a mating net where the White Rooks and Queen coordinate perfectly.
⚖️ Comparison
| Coup | Eval | Rule | Verdict |
|---|---|---|---|
| ✅ f8! | +12.32 | ✓ Safety First | Escapes the check and keeps the game going. |
| ❌ e7?? | M5 | ✗ King Safety | Walks into a forced checkmate in 5 moves. |
⚡ Opponent's Punishment
After e7:
- → xd7+ forces the King further into the open.
- → Black loses: The game ends immediately via xd7+ f6 e6+ g7
d7+.
📚 Lesson: When under check from a Knight, moving the King toward the center usually invites more powerful pieces to join the attack.
