Two Pawns and One King 29 окт 2004 07:43 It is nothing said about the following situation: 6 a2 a3 f1 I.e., whether a white pawn can jump over a black pawn from 2nd row on the 4th. Nothing is said in the problem statement, but a program which would output "WHITE WINS" for this test case gets WA on test 3. Please complete the problem description with this remark (or excuse me, if I didn't notice how to conclude an unambiguous rule for this case) And I also sent a test to yakovlev@metronome.ru, which possibly should be added to the test set, because my 2 programs, outputing different answers for this test case, both get AC.

Dmitry 'Diman_YES' Kovalioff Hints (+) [3] // Задача 1216. Two Pawns and One King 23 дек 2002 08:41 I've got AC many weeks ago but a lot of people cann't do it. The task is not so hard as one may think, but it needs this: 1) Before coding you must find out all the tricks on paper (and there are a lot of tricks) 2) Your program must have a good structure 3) You must code it very accurate, because it'll be very hard to find a mistake later So, hints: I. If your program works on 8*8 board it'll work on every board from 6*6 to 26*26 II. My program's structure is following: 1) if black pawn (BP) stops white pawn (WP) -> BLACK WINS 2) if BP bites WP -> BLACK WINS 3) if WP bites BP (on first move, of course) and saves itself (runs away from square and black king (BK) can't catch it after that) -> WHITE WINS 4) if BK is in square (it can catch WP) and BP cann't prevent it standing initially on BK's way -> BLACK WINS 5) if BP trasforms into other figuge (I considered that it transforms into queen) and bites WP -> BLACK WINS otherwise -> WHITE WINS III. Here are some tests for you on every case described above: 1) 8 a2 a7 h1 BLACK WINS 8 a6 a5 h1 WHITE WINS 2) 8 a3 b6 h1 BLACK WINS 8 a6 b6 h1 WHITE WINS 3) 8 d5 c6 f5 WHITE WINS 8 d5 c6 a5 WHITE WINS 4) 8 b4 d5 e4 WHITE WINS 8 b3 h7 f3 BLACK WINS 8 b2 h7 g2 WHITE WINS 5) 8 b4 b3 h2 BLACK WINS 8 b5 b3 h2 WHITE WINS 8 b5 b2 b3 WHITE WINS 8 a4 g3 h8 BLACK WINS 8 a4 g3 g2 WHITE WINS 8 a4 h3 h8 BLACK WINS 8 a4 h3 g2 WHITE WINS I hope if you program passes all theese tests it gets AC.

Thanks a lot !!! It means that according to the rules of chess the pawn may(and may not) move in the first time by 2 fields ahead, not by one as usual. It is olny the first move, no more.
