Talk:X-ray (chess)

From Wikipedia, the free encyclopedia

so in this instance, which piece is being felt through which? Doops 03:21, 11 May 2004 (UTC)

Sorry I didn't see the question and reply sooner. The white rook is felt through the black rook. Specifically, the white rook on c8 defends the white queen on f8, even though the black rook on d8 is in the way. --Fritzlein 02:50, 27 Jun 2004 (UTC)

Define felt? lysdexia 05:01, 12 Nov 2004 (UTC)

The x-ray is a good thing to know, but I did not feel it showed it clearly enough. I added the second image to show the position after 2. Qf8+ where the x-ray is most clear. The variations in black's play are not illustrative given the topic at hand so I removed them, I hope that doesn't offend, I just felt that the point here is to illustrate the x-ray attack, not cover alternate moves possible and why they were not any good. The x-ray attack is subtle to chess novices and I think the second image and the additional discussion added makes it very clear. erislover

Would not the best move be to exchange the rooks to avoid this, or is this what the mistake of the novice would be? -Avochelm 12:16, 4 August 2005 (UTC)

Exchanging rooks was the line that erislover deleted in the interests of clarity (I understand the reasons for doing so, but I wonder if it's going to cause more confusion than englightenment; perhaps it's better to find a "cleaner" example of the X-ray which doesn't have such sidelines?). The line is question is: 1.Rc8 Rxc8 2.Qe7! Qxe7 (if 2...Qc6 3.d8Q+ is neatest) 3.dxc8Q+. --Camembert 13:01, 4 August 2005 (UTC)

The alternate lines can get pretty complicated, but since someone asked about it almost immediately after I removed it, I guess it was best to have it in. In that case, I have tried to be thorough. It still strikes meas distracting, but these are the compromises that must be reached. Players advanced enough to see the possibilities without mentioning it would already know the x-ray attack anyway, so the alternate lines do make sense in that light.
