  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??

  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

  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?

  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."

CROSS-PIN
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>’s 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.

  Honza Cervenka: Superior calculation won here. White hoped that after 17.Nf6+ Bxf6 18.Rxf6 his attack can compensate or even avoid loss of QS Pawns but Petrosian foresaw that he can grab the Pawn and eliminate white's attack with decisive advantage. 17.c4 was more reasonable.
