Another Broken Puzzle

After the first moves: ... Re8 Qf4
The puzzle only accepts as continuation: Qe7

There's however a second line: Re1+ , that registers as "failed". In an outside engine I use, this line is actually considered better. I checked at 30+ plies deep.

The puzzle should consider both lines. Right now it's rated as 2500, because it's broken.

Also the continuation: g5 should be considered as "you can do better". At 30+ plies deep it's close to the other 2 lines.

what engine are you using?

I use a program called "Scid vs PC" . It uses Stockfish. Might not be the latest version.

Yep, browser analysis confirms broken puzzle.
