Sudoku Players' Forum (clone)

Hello,
i started playing Sudoku about 2 weeks ago and i have serious problems solving this one here.
Please help me solving it and even more important tell me how you did it^^

There is still one simple move left, though it doesn't really get you anywhere. In block 2, you have left in some pencil marks for 4 which are not allowed due to the 4 in R3C1. That leaves the only possible locations for 4 in block 2 in row 1, which we can use to eliminate the 4 in R1C7.

After that, look for a naked triple in column 6, which should leave the puzzle fairly easy to solve.

Yeah i noticed that mistake later but i couldnt change that anymore.
Thanks for the help i found the naked triple and solved it =)
