Stuck in this sudoku. If anyone can solve this then please share the method.
As Glorfindel has found, you can
eliminate the 9 in R1C6 and the 2's in R3C6 and R7C6
Then, there's a chain:
If R5C4 = 9, then R5C9 = 8, R7C9 = 9, R7C8 = 8, R1C8 = 9, R1C5 = 7, R6C5 = 2, R4C5 = 9, R5C4 is not 9.
This is a contradiction, so you can eliminate the 9 from R5C4.
Then another chain:
If R6C4 = 7, then R6C5 = 2, R4C5 = 9, R1C5 = 7, R1C6 = 8, R3C6 = 5, R3C4 = 2, R7C4 = 7, R6C4 is not 7.
This is a contradiction, so you can eliminate the 7 from R6C4.
The rest is trivial.
Not an easy puzzle. I could not find easier techniques to use.
A simple hint:
In column 6, you've correctly identified that rows 2 and 8 can only be 2 and 9. That means row 1 can't be a 9; row 3 can't be a 2; and row 7 can't be a 2 either.
This technique is called a naked pair; it seems you've used it already in row 7 to eliminate the 9's in row 4 and 6.
