I lost on time again.

I wasn’t sure what to do after Rd8.

Ng6+?

After hxg2, the king cannot go to h2 because…

Look for a pin.

This one took me a long time.

F4? I’m so blind!

Rd1+?

Ng2? Queen can just go f1.

I saw Rxg4, but I didn’t realize h-pawn cannot take the rook.

If I had noticed the pin, then I’d know Ng2 comes after Rxg4.

Qf7+?

If Qf7, then …Kh8.

Qxd8, …Kg7. Unclear.
