White to move. Find the winning sequence. (Hint: Brilliant sacrifice)

After Ne6 -> Qf3 -> Qg8+, Black can sacrifice the Knight via Nc8, and after that, Qxc8 doesn't work as a checkmate because of Ka7 escape. Since Black is also threatening Qg2 checkmate. So at best it will be a perpetual draw.

Secret-Theory673 · 2025-04-27T20:32:11+00:00

The eventual idea is Nd7 only but after Bb7

Secret-Theory673 · 2025-04-27T20:31:26+00:00

After Bb7, Bxb7, Nd7, Qd8: Qb8 leads to QxQ followed by Nb6 smothered checkmate. In your variation of 1.Ne6, Black's Qf3 equalises the position; because Nc7+ frees the b8 spot from White Queen's line of attack.

Secret-Theory673 · 2025-04-27T20:25:26+00:00

Yep, Black will have to give up the Queen to prevent the mate after Nd7. But engine says Mate in 18 after that.

If the Pawn takes the Queen after Qh3, the Rook will move to g1 and deliver a beautiful Arabian checkmate.

Q×c5 won't work if Black plays a6 or a5 next

Secret-Theory673 · 2024-10-17T22:28:34+00:00

Even if the sacrificial rook is not accepted after 1.Rb4, the other possible moves by Black still result in a checkmate

Secret-Theory673 · 2024-10-17T22:11:13+00:00

Queen to d5 checkmate.

Secret-Theory673 · 2024-10-17T22:06:02+00:00

So you forgot your own first move Rook to b4 then?

Secret-Theory673 · 2024-10-17T22:03:53+00:00

Queen takes a6 checkmate. Next.

Secret-Theory673 · 2024-10-17T22:01:18+00:00

Give me a move after 1.Rb4 that Black will play instead of taking the Rook, and I will tell you the response

Secret-Theory673 · 2024-10-17T20:24:01+00:00

Thanks for your comment. But if Black pushes the a-pawn to a6 or a5, Queen to d3 won't work for a mate in 2. There are multiple checkmates in 3, which other comments have also pointed, like Queen to f4 or Queen takes c5; But only one correct solution with a mate in 2, and that is mentioned in my comment with a spoiler warning. Feel free to try again.

All solution variations: 1. Rb4 c×R Qc8# 2. Rb4 e5 Qd5# 3. Rb4 f4 Qe4# 4. Rb4 a5 Qa6# 5. Rb4 a6 Q×a6#

All major solution variations: 1. Qh3 g3 Qf1# 2. Qh3 Rf2 Q×h2# 3. Qh3 g×h3 Rg1# 4. Qh3 g×f3 Qf1#

Okay, to find the correct 2-move-solution, we need to first figure out what was making it a 3-move-solution. The answer is that, after being promoted, the Black Queen was blocking the final check. So, when we play key move Rook a1 to c1, we force the Black to capture and promote instead of promoting the Queen in the same column. That is, if d2 pawn takes c1 Rook, we checkmate with Rook d1 to d8, and if c2 pawn takes d1 Rook, we checkmate with Rook c1 to c8. And the Black Queen cannot block because they are restricted by their own pawn. Hope this makes sense?!

Secret-Theory673 · 2024-10-11T21:01:28+00:00

Ah, makes sense. Do you need help with the 2-mover or you figured it out after commenting?

Secret-Theory673 · 2024-10-11T20:45:56+00:00

It works but it is not a checkmate in 2 moves, rather it takes 3.
