Feb-17-05  samvega: Nice cross-pin. Presumably Petrosian msut have planned it at 24..h6.

  tpstar: <samvega> Thanks for pointing out this game. The cross-pin is one of my favorite tactics, beautiful but rare, and seemingly more common on diagonals = Morphy vs T Lichtenhein, 1857 but can you think of other cross-pin examples on ranks and files?
Feb-18-05  Cyphelium: <tpstar> Tal's beautiful 34. ♖a8! in this game would perhaps qualify? Tal vs B Brinck-Claussen, 1966
Feb-18-05  Hesam7: Is the cross-pin attack another name for X-ray attack??
Feb-18-05  samvega: <Hesam7> I used the term "cross-pin", but just plain "pin" was probably more accurate. OTOH, the example <tpstar> gives (18.Qxg7 noted in the kibitzing, but not actually played) is a perfect and charming example.

"X-ray" to some is synonymous with "skewer", but there is a more specific definition too. Let me see if I can track down an example of what I consider to be an x-ray

Feb-18-05  samvega: <Hesam7> OK, this is what I think X-ray means: Morozevich vs Kramnik, 2001
After 23..Nd2, the knight is protected by the rook at d8, despite the intervening white rook at d3.

That is my understanding of an X-ray, but I could be wrong. No doubt <patzer2> will be able to give an unambiguous definition, and perhaps some illustrations?

Feb-18-05  samvega: X-RAY
A brief survey of the net shows "X-ray" frequently used synonymnously with "skewer". But I also find the following definition: "X-Ray: When a piece defends a friendly unit on the same line, despite an opposing piece being in between them. The defending piece x-rays the opposing piece."

This term is also ambiguous. The term can refer to a double pin (i.e. a piece pinned against two other pieces, by two different pieces) -- <tpstar>ís example illustrates this. The term also refers to cases where a piece exerting a pin itself becomes pinned. For example, in the game B Ivanovic vs Tal, 1979 if black tries 20..Rg5, then white can safely reply 21.f4, because the pin 21..Bd5 fails to the cross-pin 22.Bc4.

Feb-18-05  Hesam7: <samvega> Thank you it was a real hard work searching position for this rare tactical stroke. What I understand from X-ray attack is illustrated by <tpstar>'s example 18.Qxg7! Once I had a russian book on tactics (consisting only from exercises and their solutions, I think the name was something like "Combination Art" I am not sure if you know the book please inform me, it was an excellent book) and one chapter was devoted to this topic.
Feb-18-05  samvega: oops, lost the URL there ... that was: " the game B Ivanovic vs Tal, 1979 if black tries 20..Rg5, then white can safely reply 21.f4, because the pin 21..Bd5 fails to the cross-pin 22.Bc4."
