马兵残局 is a interesting and difficult endgame. 马底兵vs单士象 is especially interesting. It was said to be a win pattern in some places, and draw pattern in other places. If you look 马兵残局 up at 东萍棋谱仓库, you will see 5 positions are said to be draw. These positions are copied from endgame book. However, if you look up these positions from EGDB, you will see they are all win positions. According to the statistics page of EGDB, 马兵vs单士象 is win for red, even it is 马底兵vs单士象. The following links are some posts pertain to this topic.

數年前蔡福如老師曾向我提過馬底兵有仕或相例勝士象，如果沒有紅方沒有士相則可勝可和。
不過自從拜讀了貴殘棋庫後，發覺就算紅方沒有士相也是例勝，可惜我自己仍未有時間慢慢鑽研。
其實除了馬兵對單士象、馬兵對卒雙士這兩個殘局外，我對炮兵單士象對士象全也十分有興趣，因為這個在坊間的書中基本上甚少提及。
其實貴殘局庫真的非常好，是一個學習殘局的好地方，不過好像長將長捉(Order)那個問題仍未解決，導致有一些車兵殘棋出現了 bug。
Which bug? Could you show it by example? I will be very happy to learn it and correct it if possible.

這一局似乎走車七進二應該比車七進三快。

這一局紅兵不用避捉，黑長捉過河兵犯例。
:D
Well, is it a bug?
This question was raised a few time, so I will answer in the next post.
