</td></tr></tbody></table> <p>振り飛車側がスムーズに石田流に組むには、△8五歩の前に▲7八飛-▲7五歩と指しておき居飛車の飛車先を浮き飛車で受ける形を間に合わせておけばよい。しかし居飛車が早めに飛車先を決めてきた場合、振り飛車は▲7七角と上がるしかない。これを不満とみれば、▲7六歩△3四歩のあとに角道を止めず▲7五歩を突く手もある（図2-A）。 </p><p>図2-Aから△8四歩なら▲7八飛と飛車を振る（図2-B）。ここで△8八角成▲同銀△4五角には▲7六角（図2-C）でよい（△2七角成ならば▲4三角成で先手が有利となる）。この手順を避けるため図2-Bから△5四歩や△4二玉と穏やかに指してくれば、振り飛車も▲6六歩と角道を止めて石田流本組に組むこともできる。これで居飛車が不利というわけではないのだが、居飛車が石田流本組に組まれるのを嫌えば図2-Bの次に△8五歩と飛車先を伸ばしてくる手があり（図2-D）、ここから三間飛車側から乱戦に持ち込む手順がある。これを<b>早石田戦法</b>（はやいしだせんぽう）という。 </p><p>手順としては図2-Dで先手が▲4八玉と上がった後に後手が△6二銀とすれば▲7四歩と仕掛ける。△7四同歩ならば▲2二角成△同銀▲5五角で、以下△7三銀であれば▲7四飛とする。これに対して△7四銀と飛車を取る手には▲8二角成となるので、△3三角や△6四角とし、以下▲7三飛成に△5五角▲8二龍△同角▲8三飛△7二金▲8五飛成△9四角が定跡として知られている手順である。また△6四角では▲同飛△同銀▲1五角もあり、以下△4二金や△5二玉ならば飛車の利きをさえぎるので▲2二角成があり、△3三桂や銀には▲同角左成から三枚替えとなる。ほかに△2四飛または△3三飛と打つ<a href="/wiki/4%E5%9B%9B%E6%AD%A9%E3%83%91%E3%83%83%E3%82%AF%E3%83%9E%E3%83%B3" title="4四歩パックマン">4四歩パックマン</a>のような受け方もある。このほか▲7四歩の仕掛けで△7四同歩に対して単に▲同飛とし、以下△7三歩▲7六飛もある。△8八角成▲同銀△4五角には▲5五角△6七角成▲7九飛の展開である<sup id="cite_ref-17" class="reference"><a href="#cite_note-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup>。 </p><p>なお本来早石田は後手番で仕掛ける戦法とされる。その際上記の手順で▲4八玉（つまり△6二玉）の一手がなく居玉での仕掛けとなるが、上記と同じ手順をたどる。このほか、<a href="/wiki/%E6%96%B0%E9%AC%BC%E6%AE%BA%E3%81%97" class="mw-redirect" title="新鬼殺し">新鬼殺し</a>で後手が戦法の誘いに乗らずに角交換せず△6二銀と指す場合にはこの後手番早石田の手順に合流することもできる。先手番早石田と異なり▲7七角と一手掛けているので手損になっているためで、△6二銀に以下は▲7四歩△同歩▲2二角成△同銀▲5五角である。 </p><p>こうした手順を避けるため、▲4八玉△6二銀▲7四歩の仕掛けには△7二金もある。以下▲7三歩成に△同銀▲7四歩△6四銀といった手順がある。 </p><p>玉を囲わずに敵陣を攻める早石田はハメ手と言われ、攻撃力が高かったため、アマチュア間で指された。しかし早くに防御方法が定跡手順化され、早石田側が不利という結論が出たため、<a

</p><p>この7手目▲7四歩は江戸期の定跡で悪手とされ、第30期名人戦でも出現したが仕掛けた升田が敗北しており、成立しない仕掛けとされていたものである。しかし、石田流の勝率が悪いことを嘆いていた鈴木が、棋士仲間と石田流の研究をしていたときに鈴木が再度研究し直したところ、仕掛けとして有効であることが判明したものである。▲7四歩以下は、△同歩▲同飛△8八角成▲同銀△6五角（図4-B）▲5六角△7四角▲同角△6二金▲5五角（図4-C）という進行が一例。従来は△6五角（図4-B）と合わせられ、先手失敗とされていたが、以下、△7三歩▲5六角で▲１一角成を見せる手が発見され、仕掛けが有効だと判明した。次の▲1一角成を受けるには△1二飛と打つしかなく、△3四角と一歩得して先手十分。鈴木はこの新戦法開発により第32回<a

title="大山康晴">大山康晴</a>名人（当時）に勝利。駒組みの分かりやすさもあってアマチュアで大流行し、当時は縁台将棋では先手後手ともに升田式石田流となる相升田式という珍将棋まで登場した<sup id="cite_ref-27" class="reference"><a href="#cite_note-27"><span class="cite-bracket">[</span>* 2<span class="cite-bracket">]</span></a></sup>。 </p><p>名人戦第2局は升田先手番で、初手から▲7六歩△3四歩▲7五歩△8四歩▲7八飛△8五歩▲4八玉と進むと、実戦は以下▲7六飛と石田流に進めた先手が作戦勝ちとなり、押しきる。続く第3局、初手からの進行は▲7六歩△3四歩▲2六歩△3五歩▲2五歩△3二飛と、後手でも石田流を目指した。その次の局（第30期名人戦七番勝負第3局）で後手番の升田幸三が使ったことによって先手のみの定跡だった早石田が後手でも使えることが判明した。この第30期名人戦はフルセットの末、大山康晴が防衛したが、その7局のうち5局が升田式石田流であった。初手から▲7六歩△3四歩に▲7五歩がその出だし。△8四歩▲7八飛△8五歩に飛車先を放置して▲4八玉と上がる。ここから早石田が升田式となるのであるが、あとは玉を美濃に囲っていく。後手が途中△8六歩▲同歩△同飛とくれば、▲2二角成△同銀▲7七角、もしくは▲8八飛で対応可能である。 </p><p>升田式石田流の基本となる駒組みとして、▲7八金とこちらに金を使うのは<a href="/wiki/%E4%B8%8B%E7%94%BA%E6%B5%81%E4%B8%89%E9%96%93%E9%A3%9B%E8%BB%8A" class="mw-redirect" title="下町流三間飛車">下町流三間飛車</a>同様、角の打ち込みを消している意味である。次に▲7七桂と跳ねて△4四歩なら▲8五桂を狙う攻めがある(△同飛は▲9六角)。ただし、▲7七桂と跳ねると▲8八銀を使いにくいのがネックである。これは後述のとおり▲7七銀も有力であって、こちらの手の狙いは△4四歩には▲6六銀～5五銀と中央に繰り出す手、または▲8六歩△同歩▲同飛と強く飛車交換を目指す攻めが考えられる。いずれも軽快に動いていくのが狙い。▲7七桂型は後述のとおり▲9六角が狙いの一手で、△9四角と飛車先の歩を守る手を指しても▲8五桂△同角▲8六飛で、今度は角取りが受からない。したがって名人戦第2局では▲9六角に後手は△5四角とし、以下▲4六飛△7四歩と進んだ。升田はのちに「昔から後手番の石田流は悪いとされてきたが、本当にそうなのかどうか、疑念をいだいていた。それに、悪いといわれるとやってみたくなるのが私の性分である。もちろん悪いから指すのではない、自分で納得することが前提なのである」と著書で書いている。 </p><p>早石田に対して後手居飛車側が図3で△8六歩▲同歩△同飛は▲7四歩があり、以下△7四同歩は▲2二角成△同銀▲9五角の王手飛車、△6二銀も▲2二角成△同銀▲7七角の両取りがある。7四歩を手抜いて△8七飛成は▲7三歩成△同桂▲2二角成△同銀▲7三飛成（▲5五角は△3三角）△8九竜▲9八角で居飛車が特段有利な展開にはならない。そこで△8六歩を保留し△6二銀とすると、上記図2-Dのときと同じように▲7四歩△同歩▲2二角成△同銀▲5五角△7三銀▲7四飛△6四角▲7三飛成△5五角▲8二龍▲同角と進めると今度は▲8四飛がある。先手の玉が4八に移動しているので△9五角の切り替えしが利かなくなっている。以下△7二金に▲7三歩△同桂▲8三銀が生じている。したがって、△6二銀▲7四歩に△7二金▲7三歩成△同銀と応じる必要がある。局面的には先手が▲7八飛と▲4八玉の二手しか指していないことになるが、居飛車側は六手指している勘定になる。このほか、△8六歩▲同歩△同飛▲7四歩に△8七飛成もあり、以下▲7三歩成は△6七龍▲6八金△7八龍▲同金△8八角成▲同銀△7三桂とし、▲5五角であると△7五飛▲7七角に△6五桂が利く他、▲7四歩も△7五飛の返しがある。

title="後手">後手</a>で大きな違いが現れる。急戦法のため、一手の違いが大きく響くからで、後手の早石田は先手と比べてリスクが高かった。居飛車先手の場合は▲2六歩が入っているため、△3五歩に▲6八玉や▲5六歩とすると△3二飛に▲2二角成△同銀▲6五角の筋が利くためで、前後逆の居飛車が後手ならこのとき振り飛車側が▲8五角と打ち返しが利くが、居飛車先手の場合はこの手順が利かない。したがって、後手早石田の際に▲6八玉ならば△4四歩として以下▲2五歩△3三角となる。『イメージと読みの将棋観』（2008、日本将棋連盟）では羽生善治は△4四歩▲2五歩△3三角の順になれば先手がかなり得をしているとし、森内俊之も実践なら▲6八玉を選び、以下△4四歩▲2五歩△3三角▲7八玉で、もし△3二銀ならば▲3八銀とするという。この先手陣の構えは2002年に<a
