Ever found yourself staring at the chessboard wondering how to gain an advantage over your opponent? Two powerful techniques to gain material or attack their king are the X-ray and skewer. You’ve probably seen masters use them in famous games to turn the tide and grab a win. While they may sound complicated, X-rays and skewers are actually quite straightforward to understand and use in your own games. Once you know how to spot the opportunities and patterns, you’ll be unleashing X-rays and skewers on your opponents before they even know what hit them. Read on to have these potent weapons added to your chess arsenal so you can start attacking with confidence.
Understanding the X-Ray Attack in Chess
The X-ray attack in chess is when a piece moves to attack an enemy piece behind another enemy piece. This clever tactic allows you to threaten pieces that seem protected.

In the position above, White moves from b5 to e8 unleashing a deadly X-ray attack that forces Black to be mated after 1…Rxe8 and 2. Rxe8#

In this second position, Black can opt to exchange queens with 1…Qxc2 but that’s completely losing for Black. Black can turn the tables by capturing on c1 instead, revealing a checkmate in 3 moves!
The game goes thus: 1…Qxc1+ 2. Qxc1 Rxc1+ 3. Rf1 Rxf1#
To understand and use the X-ray attack, here are a few tips:
Look for diagonal, horizontal and vertical lines
Scan the board for straight lines where your pieces control squares beyond the enemy pieces. Pieces like bishops, rooks, and queens that control lines are good for X-ray attacks.
Find loose pieces
Loose pieces have limited mobility and less control over key squares. Target knights in the center of the board or bishops hemmed in by their own pawns. These pieces can be vulnerable to X-ray attacks.
Create deflections
Use one piece to lure away the defender, allowing your other piece to swoop in for the X-ray attack. Deflect the protector and the victim will be exposed.
Calculate responses
Consider possible defenses and counterattacks before launching your X-ray assault. Make sure the attack leads to a gain of material or strategic advantage. If your opponent has a simple way out that leaves you worse off, look for a better option.
With practice, you’ll get better at spotting opportunities for X-ray attacks and using this clever tactic to gain an edge in your chess games.
How the Skewer Differs From the X-Ray
The skewer and x-ray are both tactical chess moves to attack your opponent’s pieces, but they work in different ways.
How the Skewer Works
A skewer targets two enemy pieces on the same line (rank, file, or diagonal) and threatens to capture the more valuable piece. Your opponent has to move the attacked piece, allowing you to capture the other piece.
For example, say you have a rook on the a-file and your opponent has a queen on a8 and a bishop on a6. By moving your rook to a7, you skewer the queen and bishop. Your opponent has to move the queen to avoid capture, so you can take the bishop. Pretty sneaky!
Or let’s have another visual example:

In this position, White’s bishop on f3 is doing a great job attacking both the queen and rook at the same time. Black has to move the queen to avoid significant piece loss after which the bishop takes the rook, a major plus for white. This is a great example of a skewer.
The key is spotting your opponent’s pieces that are lined up and choosing a move that attacks the more important piece. Your opponent essentially has to give up one piece to save the other.
How the X-Ray Differs
An x-ray also targets two enemy pieces on the same line, but it’s when your piece moves to attack a less valuable piece, threatening to capture a more valuable piece behind it. Your opponent has to move the piece in front to protect the piece behind.
The key difference is that with an x-ray, you attack the less valuable piece to threaten the more valuable piece behind it. Your opponent has to block your view to the more valuable piece by moving the less valuable one.
Conclusion: X-ray vs Skewer in Chess
So there you have it, the x-ray and skewer are two powerful yet often overlooked techniques in chess that can help turn the tide of battle in your favor. Once you start looking for opportunities to unleash these weapons, you’ll find they pop up more frequently than you expect. Just remember, the key is to visualize the board from your opponent’s perspective to spot their loose or unprotected pieces. Then swiftly swoop in, snatch up the material, and watch with delight as your position – and confidence – grows. With practice, these techniques will become second nature and you’ll soon be the one gaining the advantage and keeping your opponent on the defensive.
