3/5 and 4/5 are also simply winning positions. At least 5/5 makes you find a perpetual check salvaging a draw, but that one is also disappointingly simple for anyone who's ever heard of perpetual checks.
Edit: correction, one of 3/5 and 4/5 was forcing a draw with a simple knight fork. Still too simple and doesn't live up to the name of the lesson. Was hoping for ways to complicate slightly worse positions for counter-play, for example.
I don't remember what 1/5 was, but it's really an overwhelmingly disappointing lesson overall. You guys should consider remaking the challenges. I think you can keep the video though.
The name of the lesson is "Playing a bad position", and it's exercise 2/5.
"White is down two, connected passed pawns and Black's queen is attacking both the unprotected bishop and rook. White's position looks terrible - how can White avoid losing even more material?"
And it gives a completely winning position where white simply wins a queen. What? Am I hallucinating, and I'm actually in the "make your opponent resign with one move" lesson?
Here's the FEN for the position: 6k1/p1r2pp1/1p3b1p/5q2/Q7/5BP1/5P1P/1R4K1 w - - 0 1
It's apparently an "Advanced Lesson", and even though I'm not a very advanced player I spotted the tactic immediately. What is it doing there? Terrible.
