7….. Qxg5+
8.Ka6 Bxa7 This clears b8 for flight which will be blocked by white’s next move. Unfotunately for black his Q can not pin b6 P because of white P at c6 creation of black’s own folly.

11.Kxb6 Thank you good knight! You have saved me from stalemate.

This may not be the best but just eye popping.
You may have looked at it, but you might take a look at the line 3. …..Nc4+. You mention this move as a variation at move 5 in the main line.

I will only say the ending is more, shall we say, prosaic than the main line you gave above with the stunning combo of 7.Qg5 and 8.Ka6. However, it is a hole in the main line that has to be addressed.
And also, looking back through my notes on this puzzle, the line where black plays Nc4 at move 2, though those lines branch off in many ways subsequent to it, white appears to win many of those prosaically, too.

2…. Nc4+ 3.Kb5 White K has no access to a6 unlike in the case of 5….. Nc4+ . Now 3…. Nxe1 is similar to the main line before. 3…. Be5 Black tries to fish in troubled waters.Now 4.Kxc4 is totally lost to white and is a trap.The B guards g7 square and blocks R’s access to 8th rank and also tries to deflect white R as shown in next move.4.Rxe5 Nd6+ 4…..

12:03 a.m. comment inadvertently shows “P says” but it is mine. i did not click the suggestion after I typed “P”.
I have checked 1…. Kb8 trying to move to c8 but trying to get out of quicksand will draw black k more into quicksand.Also 5…. Nc4+ does not bite anything.
Congratulations! I can appreciate your genius. After 9. c7 black has no alternatives to stop mate. The best continuation for black would be 9…Qa5 10.Kxa5 Kb7 11.bxa7 and then black can decide which pawn gets promoted for the mate. The puzzle was created by Leopold Mitrofanov back in 1967 and was awarded 1st prize. I think it’s one of the greatest puzzles of all time, in my humble opinion…

Thank you John,
However my sacrifice 2.Re1 can not be termed deflection ;It can at best be called Road block sacrifice . It was found by chance. I tried 1.Rh4 but found N guarding the square ,I turned back and put it at e1,then only it dawned that the N capturing it blocks the path of Q. Later Q sacrifice is deflection ,o.k.
AN OVERWHELMING DISCOVERY FOR A WEAK PLAYER LIKE ME.
Come on, Chakravarty ,
It is a simple problem.Go at it.
Mate in 2
1 Nc6+ bxc6
2 Bc5++
White to move and win…
8/k7/P2b2P1/KP1Pn2P/4R3/8/6np/8 w – – 0 1
Being intimately familiar with this very famous puzzle, I will wait to see what other have to say before commenting.
Yes, this one of my favorites. White has to make some bold moves or else lose it all completely.
Very interesting position. Win seems to be there but there are some loose ends. They have to be tightened.
Think about deflection via sacrifice…

A nice composition, with half a dozen spectators on the right side of the board.
White starts the proceedings by sacrificing his knight at c6+. After the b pawn captures the knight, the bishop closes the deal at c5.
