If you are looking to update your knowledge of opening traps, there is a new site that seems to have gone to a large amount of effort to put them all in one place. ChessTraps.net have over 1000 opening traps, all explained via short video. You can select them by ECO code, by name (if you know what they are called), or by level of difficulty. The other great thing about the site is that it is free, meaning no bothersome registration process.
I've just dipped my little toe into the water, but have already found at least one interesting line in the Max Lange, the Maayan Trap. Hopefully there will be more sneakiness awaiting me.
