Kibitzer's Corner
Nov-10-03  Shadout Mapes: Here's a fun one. Can't say I liked white's opening system, though. And I don't see how this si similar to the position shown on the A11 page.
Nov-10-03  JSYantiss: I didn't like White's opening here either, but couldn't he have played 14. Qxc8 and come out of it down only two pawns?

Then again, the two key factors here are 1. the word ONLY and 2. His opponent was Reshevsky, who would have taken that two pawn advantage to the bank. :)

  Eggman: Is it proper to speak of being down two pawns because one is down two points? In any event, White could have played on for a bit (I certainly would have), but against Reshevsky he is no doubt lost.

Tell you one thing: I doubt that Reshevsky as White would have resigned - he was known for pulling off some great come-from-behind victories.

  MoonlitKnight: Sam must surely have realized the combination when he played 10...♘d7.

  patzer2: After 11...a5! Reshevsky has a clear advantage. Black was already threatening to win a pawn or the queen with 12...axb4, but Castaldi makes it a clear win for black with the blunder 12. Ba3?? Relatively better was 12. Qd1 or 12. a3 or 12. b5, although black still holds the advantage.

  kevin86: oops,queen trapped!
Oct-15-04  WMD: Castaldi beat Reshevsky at the 1937 Olympiad so this game was probably sweet revenge.
Dec-13-04  GreenDayGuy: Instead of 12. Ba3, maybe 12. b5 Ne5 13. NXP would have given white a good game.

Weteschnik, "Understanding Chess Tactics", pages 204-205:

<So if you take or recapture a piece you should know how to leave the square you took on (in case you can be attacked there). Here Castaldi-Reshevsky, Dubrovnik (ol) 1950, is quite instructive.

1 ... axb4! 2 Qxa8 Nb6

And the queen is trapped.>

12 ... a5xb4! 13 ♕a4x♖a8 ♘d7-b6 <trapped piece> 0-1

So White is forced to resign here on move 14(!) simply because he did *not* have a plan for extracting/retreating his queen from the a8-square if it were to be attacked.

<<<Weteschnik emphasizes that you must determine this "exit strategy" <BEFORE> you commit your piece to a particular square.>>> You simply *cannot* do what White does here, plan to play 13 ♕a4x♖a8 and then wonder how in the world you are going to save Her Majesty after Black attacks it with 13 ... ♘d7-b6.

Oct-25-08  AnalyzeThis: This is really cute!! LOL.

Yes, very nice, forcing a win on move 14.
