No Knight Step Sudoku (Daily Sudoku League #153)

It was the year 2000 when I started solving puzzles seriously and the internet was a luxury in India at that time. The Internet started becoming affordable around 2004 in India and that time if I wanted to solve any puzzles online then the Janko website was the only website that contained almost all the puzzle variations in bulk to be solved online. Today this site has grown even bigger. For any Puzzle and Sudoku enthusiast, I recommend this website very strongly. Moreover, many of the readers wanted to solve the Sudoku puzzles appearing on my blog. So now you can get these puzzles on the Sudoku Variations page.

Coming to today's puzzle, there were many puzzles that I could have posted today. However, No Knight Step Sudoku is the Sudoku type that is going to appear in the forthcoming round of the World Puzzle Federation Sudoku Grand Prix. So I thought to publish this Sudoku type for the practice to this championship.
No Knight Step Sudoku is also known with another name Anti Knight Sudoku. Both the names are famous and used in different Sudoku Championships. Here I keep using both the names for this type of puzzle. Today's puzzle is having a narrow solving path and will be fun to solve for the experienced players. However new players may find this Sudoku tough.
One more change I am doing starting today is that the file name of the Sudoku image will contain the timings of Prasanna. This is the time he took while testing this puzzle. Prasanna is currently ranked 7th in the 2015 World Sudoku Championship. So you can compare your timings with one of the best Sudoku players in the world. From this timing, one can also guess the difficulty level of the puzzle. I am constantly looking for feedback to improve my puzzle creation skills as well as this website. Do keep sending me your valuable feedback.
This No Knight Step Sudoku I am posting in The League of Extraordinary Ladies & Gentlemen as the 153rd puzzle in this series.
