Hey zorawar13, You're right it's a blunder, but there's a different reason.

Blunder: loses at least a whole piece (being already a piece down) to 1.Nxd7, since d7 is protected by White's queen (1.... Qxd7?? 2.Qxd7 1-0), and now black's R on f8 is attacked and nowhere to move to, so will lose an exchange as well.
There is also 1.Qxh7+ which looks interesting, but I don't think it works out well: after 1.... Kxh7, 2.Bxg6+ Kg8, 3.Rf3 fxe6 (or ...Nxe6), 4.Rh3+ Bh6, 5.Rxh6+ Kg7 and White's attack is over.

After 1.Qe6+ Kh8 and 2.Nf7+, Black has ...Rxf7 instead of ...Kg8?. And White's queen could be in trouble after 3.Qxf7 f5! threatening ...Nd6 and ...Nf8. This line seems to me risky. I think simply taking the knight on d7 is safer and still winning.
Hey fellow NESA Chess Players,
King_Zakadion nailed this one really fast! The correct answer is (b), White is better. The actual game continuation, after 24. … Nb4, was 25. Rxc7! Nxd5 (25. … Rxc7? 26. axb4 +/-) 26. Rxc8+ Kg7 27. Rfc1 Qxf3 28. Bf1 Nf6 29. Bg2 Qh5 30. R8c7 Qh4 31. h3 Qg5 32. Rxa7 Nd5?? 33. Rc5 1-0 on time. Although White won due to an eventual blunder by Black, with better play by Black it’s hard to tell whether the extra Pawns are enough to guarantee a win against the Queen or work up an attack on the King. Therefore, (b) is the best answer.
The Thirteenth Chess Lesson Problem was also submitted by King_Zakadion. This one requires very careful analysis of what initially looks like a simple problem, because the actual combination is several moves deep.
The question here is to evaluate Black’s move in this position, … f6. Is it a good move, inaccuracy, or blunder? Explain why.
Good luck, solvers!
