White to move and checkmate in 5.
2b2R2/1p6/r5k1/3p2Np/2r3pP/2P3P1/p1PK4/5R2 w – – 0 1
At fist I only got mate in 6 so I spent 11 minutes to solve it.
1. Rg8+ Kh6
2. Rf7 Rd4+
3. cxd4 Bf5
4. Rh7+ Bxh7
5. Nf7#
This was a tough one. The first two times this was posted here in 2014, many commenters found the mate in 6 that starts with 1.R1f7, but mistakenly thought it was mate in 5 by overlooking a sacrificial delay at black’s second move that cost white a move to deal with.
Did I miss something? Mate in 4 after r1f7…after a desperado check with rd4 check pawn takes rook what is stopping rg8 check rh7 mate?
Puzzle for Alena:
8/8/4k3/3N3K/7p/4B3/p7/7b w – – 0 1 White to move and draw. What you will probably discover here are three starting moves, and you will have to demonstrate is why two of them fail to hold and why the third one does draw for white.
1. Nf4+ Ke5
2. Bc1 h3
3. Kg4 a1-Q
4. Bb2+ Qxb2
5. Nd3+ Ke4
6. Nxb2 h2
7. Kg3 Bg2
8. Kxg2 h1=Q+
9. Kxh1
The move Nf4 saves the knight and wins tempo. If the king moves on f5 the bishop moves on d4.
The move Nc7 loses because the h pawn moves. The bishop arrives at g2 later. the white bishop must move on d4. The king takes the knight and moves to the a- pawn to support it. Then white will give the bishop for the a- pawn.
The move Bd4 loses too. The king takes the knight immediately and attack the bishop. The bishop moves along a1- h8 diagonal. The h pawn moves and the king moves toward a-pawn to support it. The white will give the bishop for a- pawn.
Yes, 1.Nf4 is the only draw for white here.
Here is a position from a real game. Analyze it and describe the issues involved:
8/1pp4R/2b1k2P/8/3B2P1/p1P3K1/2r5/8 w – – 0 1
In my opinion it’s a draw. The white bishop must guard a1-h8 diagonal.
What would you do if you were white and trying for a win?
The position is extremely complicated, and the first time I analyzed it, I thought white had a straightforward win, but found it was more complex than I thought. Think about how white might try to queen that h-pawn, think about how black might defend against that, and then think about how white might counter that defense. The position is study-like in many ways.
I analyzed your problem. Here is the solution:
1. Re7+ Kxe7
2. h7 Rg2+
3. Kh3 a2
4. h8=Q a1=Q
5. Qe5+ Kd8
6. Qf6+ Kd7
7. Qf5+ Ke8
8. Qe6+ Kf8
9. Bc5+ Kg7
10. Qe5+ Kg8
11. Qg5+ Qf7
12. Qf5+ Ke8
13. Qe6+ Kd8
14. Be7+ Ke8
15. Bd6+ Kd8
16. Qe7+ Kc8
17. Qxc7#
I’m looking forward to your next puzzle.
