| 28 | # |
| 29 | # First there is a pattern title of the form: Pattern [string]. The |
| 30 | # string is used for identifying the pattern while tuning or debugging. |
| 31 | # |
| 32 | # Then a block of the following characters representing the pattern |
| 33 | # itself. |
| 34 | # |
| 35 | # ? : don't care |
| 36 | # . : empty |
| 37 | # X : your piece, |
| 38 | # O : my piece, |
| 39 | # x : your piece or empty |
| 40 | # o : my piece or empty |
| 41 | # * : my next move |
| 42 | # -, | : edge of board |
| 43 | # + : corner of board |
| 44 | # |
| 45 | # If a pattern must not match at the edge of the board, |
| 46 | # an extra row of ?'s in the pattern may be added. (This |
| 47 | # will not add to the time taken to check the pattern.) |
| 48 | # |
| 49 | ################# |
| 50 | # |
| 51 | # After the pattern, some supplementary information in the format: |
| 52 | # |
| 53 | # :trfno, classification, [values], helper_function |
| 54 | # |
| 55 | # These and other aspects of the pattern database are documented |
| 56 | # in the Texinfo documentation. |
| 57 | # |
| 58 | ################# |
| 59 | # |
| 60 | # Any line beginning with #, or any part of a line following |
| 61 | # whitespace is a comment. |
| 62 | # |
| 63 | # The patterns are classified into a number of different categories: |
| 64 | # |
| 65 | # EE edge endgame |
| 66 | # EF edge followups |
| 67 | # CE center endgame |
| 68 | # CF center followups |
| 69 | # EY eye stealing/saving endgame |
| 70 | # |
| 71 | # The patterns are grouped in the file by category. New patterns |
| 72 | # should be added close to a similar pattern or at the end of the |
| 73 | # category where it belongs. When a new pattern is added, the names |
| 74 | # of later patterns in the category should usually not be changed. |
| 75 | # This can be accomplished by introducing names like CC35b and so on. |
