the following puzzle only needs "basic" moves
would you classify it "hard" ?
1.......2.3.4..5....2....6..5.31.......7.8..4....95....7....4....6....8.9...2...6

I needed two triples to solve this puzzle. I would consider it Hard. Hard to me are puzzles requiring triples or quads but using only basic moves. |

using only "basic" moves, i needed a total of 8 moves
this may explain the "VH" grade

An x-wing is often easier than a triple to spot and preferable. This does not change the rating of the puzzle. If it can be solved with locked sets and locked cells and contains a triple or quad it is classified as hard in my mind.
Sometimes I can spot an x-wing easier than a naked single. This doesn't make an "easy" puzzle "very hard" |
