<P>终于找到了，看看Speedcubing对Lucky Case的定义（不知道这个被不被WCA认可）：</P>
<P>A lucky record is <STRONG>any solve of a puzzle where a step of your normal solution is skipped</STRONG>.<BR>There are three exceptions:<BR>1) You worked for it, f.i. by anticipating the next step.<BR>2) The chance to skip the step is 20 percent or more.<BR>3) The skipped step represents 3 percent or less of the total moves of the complete solution.<BR>Example: if you use the cross/F2L/OLL/PLL system, then there are 7 steps, and skipping one of the steps would be a lucky case.<BR><BR>For blindfold solving a lucky case is defined by:<BR>1) more than 5 corners are correctly oriented, or<BR>2) more than 8 edges are correctly oriented, or<BR>3) more than 3 corners are correctly positioned, or<BR>4) more than 4 edges are correctly positioned.<BR><BR>For 3x3 we have a lucky case category.</P>作者: snowchou 时间: 2008-10-21 11:48:42
