1 00:00:00,012 --> 00:00:04,625 >> Okay, here's a problem for you all to think about. 2 00:00:04,626 --> 00:00:11,108 This may be easy, may be hard. But here's a Hackenbush position. 3 00:00:11,108 --> 00:00:16,482 The two players are left, who is blue, and right, who is red. 4 00:00:16,482 --> 00:00:20,876 And the problem is, if left goes first, who wins? 5 00:00:20,877 --> 00:00:27,467 And if right goes first, who wins? Remember that the players alternate. 6 00:00:27,467 --> 00:00:32,625 Left alternates and, and, and cuts down blue edges. 7 00:00:32,625 --> 00:00:39,623 Rights can only cut down red edges. And for instance, if blue cuts down this, 8 00:00:39,623 --> 00:00:46,318 this edge down at the, the bottom, then, then this red edge here floats off. 9 00:00:46,318 --> 00:00:52,004 It's full of helium, floats off, and is no longer available through right. 10 00:00:52,004 --> 00:00:56,806 So, work on this problem. Don't look at the answer immediately. 11 00:00:56,806 --> 00:01:04,338 Go, go and sit, sit down with a piece of pencil, paper pen, or whatever and see if 12 00:01:04,338 --> 00:01:11,228 you can figure out who wins in best play if left goes first, who wins in best play 13 00:01:11,228 --> 00:01:13,094 if right goes first.
