Black fight to survive as long as possible. In this one there are some turns interesting: C3+1 C7-1(in Chinese notation red '3' and black '7' is the same file) C3+1 C7-1 C3+1 C7-1 ...... L. Lynn Smith wrote on 2003-12-30 UTCAllow me to put up my two-cents-worth. With 1. e8, Black's only response is Me9. This resulting position in Black's palace is very secure for the Soldier since neither the General nor Mandarin can capture it. Red needs only to 'push' Black into a stalemate position. The Elephant does not directly contribute to the resulting win but allows Red to make necessary moves without losing positional advantage. Remember that repeating a position merely to avoid a capture is not allowed. If Red was to start with an Elephant move, Ec1 or Ec5 or Eg1 or Eg5, Black has only the option of another Mandarin move. Moving the General will only result in a quick death. Example: 2. ... Gf10 3. xe9+ But an Elephant move by Red at this point will allow Black to draw out the game several more moves than necessary. Red responds with Ge1 instead of Gd2 to create the needed central file threat which will 'push' Black's General to one side of the 'palace'. Whatever Black's reply, Red must now create the potential for a stalemate or repeated positon. Either will give Red the win. If Black was to then reply with Gd10 or Gf10 for the second turn, Red quickly wins with a capture of the Mandarin. When Black replies with Md8 or Mf8, a capture by the Soldier seals Black's fate. If Black then moves the General to the same file as the Soldier, Red need only move the Elephant to win. If Black steps the General forward, a move of Red's General to the exposed file will now leave Black with only one option. If Black steps the lone General to the exposed file, Red will respond with an Elephant move and follow with two Soldier moves. Thus a move of the Mandarin to either forward positions will result in a win for Red by turn 4, 5 or 6, respectivefully. All that remains for Black's second move is Md10 or Mf10. We'll look at Md10 but the following can be mirrored on Mf10. Red will then preform an Elephant move. Now the Mandarin is trapped in its corner, for to move back would result in its immediate capture and Black's loss in the next turn. Black must now follow with 3. ... Gf10. Red then follows with a return of the Elephant to e3 since this will also prevent Black from moving its General back to e10 because this would repeat the position at the end of turn 2. If Black was to then reply Me9, Red would capture it and effect an immediate win. Once again, Black is left with only one option, 4. ... Gf9. Red would then move the Elephant again, this time back to its previous position. This prevents Black from making 5. ... Gf10, repeating the position at the end of turn 3. So, Black is left with only Me9. And Red follows with its capture. Black cannot take the Soldier on e9 because it will expose it to the opponent General. It has only the option of either f8 or f10. Either will result in Black's loss on turn 7, when Red merely makes another Elephant move.
