Here's the solution based on the information you provided. (note: Naked/Hidden Singles aren't listed.)

Code:
 +-----------------------+
 | 2 . 3 | . . 9 | 8 5 7 |
 | . 5 . | 2 8 . | . . . |
 | 8 . 4 | . . . | . 2 . |
 |-------+-------+-------|
 | 7 . . | . . 8 | . 9 5 |
 | . 2 . | . 3 . | 4 1 8 |
 | . 8 . | 9 . . | . 7 6 |
 |-------+-------+-------|
 | . . . | . 9 1 | 7 . 2 |
 | . . . | . 5 2 | 1 6 . |
 | 1 . 2 | 6 . . | 5 8 9 |
 +-----------------------+

   c7b6  Naked  Pair                     <> 23   r23c7
   c4    Naked  Pair                     <> 14   r378c4

 r2      Naked  Pair                     <> 69   r2c36

 r2  b3  Locked Candidate 1              <> 4    r2c6
 r9  b8  Locked Candidate 1              <> 4    r9c2

     b4  Naked  Quad                     <> 1569 r4c2,r6c1

   c3b4  Locked Candidate 1              <> 1    r2c3
