Puzzles to prevent blunders

Does anyone know of any place with a puzzle feature that can prevent blunders? After all, most games are not decided by a brilliant move by rather by  an awful one.

I think it would not be terribly difficult to design a puzzle scraper that looks through all games and finds positions directly before a player made an awful move despite several good alternatives being available, and then the puzzle can just be 'good job not making a terrible move'. There are a lot of situations where everybody watching a game comes up with the same terrible move so I don't think it's as dumb as it might seem at first. Though they might all be 1-move puzzles.

From my experience, the puzzles have been training me to avoid blunders.

The puzzles are typically sharp positions where a wrong move is a blunder. Such as your move missing a checkmate, which is certainly a blunder. Or a wrong capture order resulting in your being a minor piece down. Or thinking that the end position of a line is quiescent, when, in fact, the opponent has a zwischenzug, and you lose a rook. Those are all blunders, that the puzzles help train you out of, I think.
