Look at the candidates in C2. There is a triple 245. R3C2 must have candidates 36.
The 5 in R3 must be in C456.
R4C6 must be 4.
| Code: | 543|261
621|543

Here's what I meant.
Fill out all the possible candidates in each cell:
| Code: | 15 245 3 |246 146 124
6 24 12 |5 14 3
----------+-----------
2 356 4 |36 16 15
35 1 56 |346 2 45
----------+-----------
13 36 16 |24 5 24
4 25 25 |1 3 6 |
Look at C2. There is a triple - three cells contain only 2,4,5. Thus, R3C2 cannot be 5, and R3C6 must be 5.

sorry, my reply was a tad ambiguous.
I meant that as soon as you said "triple in R2" i spotted the solution and had the puzzle complete within 30 seconds of your tip.
thanks again for the input keith |

Fill out all the possible candidates in each cell
Look at c2:
there is a triple -- three cells contain only 2,4,5--- |
right, a "naked" trio;
or i'd say -- a "hidden" duo, c2 {3,6}
( do not fill out all the possibilities in each cell ) |
