CROSS基本型第六篇<br>

EC是在完成CROOS的同时完成第一组F2L，当然和CROOS+F2不同了。
感觉CROOS+F2L练习法中说到也比较符合实际，如果逐步按照帖子练习的话一定能成功，主要看耐心了。

如果有高手实战中经常能用到<h2>Extend CROSS</h2>，请出来说句话。
也希望论坛坛主把置顶贴中的一些语句去掉。或郑重加以说明。<br>以正视听。<br>盲拧十字很好。但是<br><h2>Extend CROSS就不适合实战了。</h2>

LZ想要说明个什么问题啊

yangzhengbao

想看看有多少人用EC<br>实践很重要，是检验真理的唯一标准。<br>刚发现一个视频，人家玩Extended CROSS用了16步。和一些“妖言惑众”的所说的10步完成Extended CROSS的说法一比有点不相信了。

EC其实很实用，对于那些有能力在极短时间内判断出cross的世界级高手来说，15s的时间如果只用来判断cross确实有点浪费，于是EC才随时运而生

yangzhengbao

也就是说一般人，或者说非职业的，都没有这个能力了。

对进入十几秒的高手而言，15s只看cross肯定是浪费。LZ可以认真地看看高手的视频，看是否有用到EC。事实说明一切。

<P>下面是引用EC的发明者Chris Hardwick主页上的一段话：</P>
<P>&nbsp;</P>
<P>“If you really want to learn the extended cross method in a way that will truly be useful to you later, you have to learn to direct solve it. Basically all I can say about this step is that you have to become so familiar with the process of following all 6 pieces in your head that it becomes just as easy to solve the extended cross as it does the cross, or the 2x2x2 for you. Naturally it will always be a little bit more difficult because there are 6 pieces instead of 4, however I've noticed that when I've practiced extended cross solves a lot I can usually see a decent solution (around 10-11) moves for most all scrambles. This method is still in the works, but my eventual goal is to average under 10 moves for each scramble, and to be able to do these solves smoothly going "slow-fast" during the F2L. If I come up with any new ideas I'll post them, but so far you know now as much as I know about the process. ”</P>
<P>&nbsp;</P>
<P>这里说他可以看到10到11步的解法，同时也说了这个方法还在研发当中，如果有新的进展会公布。但是那个网页从2006年12月以后就没有更新过...</P>
<P>&nbsp;</P>
<P>另外，Macky的CubeFreak上也有提到他自己的三阶解法：</P>
<P>&nbsp;</P>
<P>“My current speedcubing method for Rubik's Cube is the Fridrich method with the following additions:</P>
<LI>Extended cross and other block approaches to F2L when possible.
<LI>F2L cross on bottom or left. Frequent use of empty slots and miscellaneous tricks.
<LI>Multiple algorithms for corner-edge pairs to minimize pause and regripping.
<LI>Avoiding 4 wrong LL edges when fixing the fourth slot (but only when it flows nicely from the rest of the F2L)
<LI>The nicer patterns from COLL when all LL edges are correctly oriented
<LI>PLL recognition by blocks of continuous colors ”</LI>
<P>&nbsp;</P>
<P>说明世界比赛级别的选手还是在可能的情况下还是会用到EC的。</P>
<P>&nbsp;</P>
<P>PS：我个人的观点是EC和Cross+F2L要视实际的打乱情况因地制宜，虽然我对EC有兴趣，但还是没学会，呵呵</P>
