The Queen's Gambit Declined Exchange Variation is truly an opening of champions. Kasparov, Botvinnik, and Reshevsky have wielded it with White; Karpov, Spassky, and Keres have defended it with Black. Its asymmetrical pawn structure — arising from an early resolution of central tension — creates a rich variety of plans and ideas for both sides.

In this Fritz Trainer course, GM Nigel Davies explains the key strategies in depth through a series of instructive games. White's most traditional approach is the minority attack, extending influence along the half-open c-file. But sharper options are also available: advancing the central pawn majority or even castling long for a kingside pawn storm. Davies also shows how these plans transfer to similar pawn structures in the Grünfeld Defence and Caro-Kann, making this course valuable for anyone looking to improve their strategic understanding of chess.

  • Video running time: 4 hours
  • Key themes: Minority attack, pawn majorities, plans for both colours
  • Also covers: Grünfeld & Caro-Kann structural parallels
  • Instructor: GM Nigel Davies

Don't waste money on this one
Ordered in January 2026. Worked good the first few times. Now it just rotates around and around the can but doesn't cut anything. I'm so disappointed because it failed shortly after my return window closed.

Easy to use! No more hand cranking.
If you like the ease of an electric can opener, but don’t have room to store it or don’t want to drag it out when you need to use it, this is for you. I like a handheld can opener, but would get so frustrated trying to use it and turn the handle. This can opener is amazing and so easy to use. Just attach to can and push a button. It starts turning on its own and when it is done it stops. You lift it up and the lid comes off cleanly. It is rechargeable so need to worry about batteries. It tucks away in a drawer nicely. I bought my mom one too. She has arthritis in her hands so thought this would be perfect for her.

Smooth edges better than twisting
Works a lot better than the crank style and the counter top electric and you can use the lid to reseal the can if you don't use the whole thing.

Worked for only 4 months. Now produces metal shards. Dangerous
Pros: Can be used with one hand. I bought this to have after surgery that left me without use of one arm for a few months. The light blinks when you need to charge it. Only needs a 2-3 min charge for enough juice to open a can. Cons: IT QUIT CUTTING CORRECTLY AFTER 4 MONTHS. I now have to use both hands to hold it in place to get it to latch on to the can. It also requires a few rotations around the top to cut through the seal, resulting in METAL SHARDS! The metal shards are super sharp and almost invisible. I stabbed myself with one enough to draw blood. This is dangerous as the metal could fall into the food when pouring from the can.
