オープニングの「定跡」

（サイト移行中。こちらに記事を移動します）

ドラフツを始めて何局か対局を重ねると、「序盤で指しにくくなって苦しくなってしまう」、あるいは「いっつも同じ手にやられてるような気がする」ということがあります。

将棋では「定跡」というのがあって、棒銀戦法、矢倉、三間飛車、腰かけ銀など、有名で標準的な手順（＝定跡）というのがあります。初心者はまず棒銀戦法から覚えるものでした。。。

こんな「定跡」がドラフツにもあるはずなのですが、いかんせんロシア語、オランダ語の書籍ばかりで気軽に読みこなすことができません。

JCDA（Japan Checkers Draughts Association:日本チェッカードラフツ協会）の例会で時々話にのぼります。

「定跡ってあるはずなんだよねー」

「どう指すのが標準的なんだろうね－」

探してみたら、「序盤入門」とでもいうべき資料が、（英語で）ありました。

Course in draughts Part 3 Sec.2 The opening of the game.（ダウンロードはこちら）

まだまだ読みこなせていないのですが、Appendixに「定跡」とでもいうべき代表的な試合がたくさん載せてありました。それを加工して、PDN（プログラムに読み込ませる棋譜データ）をつくりましたので、参考までにのせておきます。

ドラフツの棋譜を再生する（手の評価もしてくれる）ソフトに読み込ませると動かすことができ、勉強になります。もちろん盤コマで再現してもいいと思います。

ちなみに[Event]欄に、１手目の動きとオープニングの名前を入れておきました。詳細は、上の書籍をあたってみてくださいね。

ちなみに私が使ってるソフトは

フリーソフトは、DragonDammen (https://mdgsoft.home.xs4all.nl/draughts/)

有料ソフトは、TurboDambase (http://www.turbodambase.nl/tdamhome.php)

です。

DragonDammenは、バージョンが新しくなってから、私のパソコンでは評価が一部うまく動かないようになりました。ソフトのバグなのか、私のPCの問題なのかは不明です。
