Let's call the columns numerically from left to right 1...9, and the rows alphabetically from top to bottom A...I. We'll refer to a cell using its row letter, followed by the column number.

We are going to use

the XY Wing technique

Let's consider the cells

B1, C2, D1

They conform to that pattern, with

- B1 being the middle cell, and
- C2, and D1 being the wings

We are sure that

either C2 or D1 must be a 9

which means

D2 can't be a 9

Now considering the cells

D2 and F3, they must contain 1 and 2.
They are a Naked Pair
⇒ D1 must be a 9

And then you'll be able to remove some candidates from

the G row.

You can take it from here or use this website to get hints or solve the puzzle either partially or completely.
