If you want to learn specific openings, traps, and strategies, i suggest [TheChessWebsite][1]'s youtube channel.

Also, Kevin does a lot of analysis of games between Grand Masters both historical and modern, and even covers some games involving chess computers. I find that these are great for learning the subtle tactics of higher level play, and understanding how my own play is different. Also, it lets you see what the masters are actually looking at and the way in which they plan movements.

I would like to point out this is not a good channel for "learning" chess, however it is great for furthering your own knowledge.
