Guru Setup
Hello,
I am wondering about whether or not this game would be a good setup to perhaps try to play out all the scenarios before answering the questions like a guru game. I did this when I ran the problem and played out the three possible scenarios to get the questions right. However, I know that playing scenarios out before a game can waste a lot of time and that sometimes it doesn't help at all.
The explanation just had the basic setup and did not play out any scenarios. Should I be sticking to this basic model and using guru setups only in rare cases where it is obvious there are only two scenarios or is this a good application of the guru game method? Let me know.

Thanks for the question! This is definitely a skill that is trained with practice, but in general, the fewer scenarios there are to play out, the more likely it is that you should play them out. This game, for example, has really only three possible scenarios, and this is actually a great game to map out the possible scenarios. We can tell in this game because rules 2 and 3 end up constricting the game possibilities a lot—a sign that it might be a good idea to map our possible scenarios instead of just making a basic game setup. Because of these two rules, we know that G can only be in blocks 1 or 2. If that’s true, then we know that J has to be in day 3, and T has be be on day 2, with H and U in days 5 or 6.
G T J S H/U U/H
If G is in block 2, however, then we know where G, S, and U are placed, and then we can either put J in the first or third day, which lead to our other two templates. In this game, there aren’t too many moving pieces, and there are only three templates, so it’s definitely one that wouldn’t take too long to map out the scenarios for, and these would save you a lot of time moving on later into the test because really, there are only 5 possible orderings for this game. You don’t have to stick to using the guru setups only where there are obviously only two scenarios, though those are the best examples. Sometimes, in cases like this, the guru method can be a great timesaver. If you’re mapping out scenarios and it’s getting confusing or complicated, that’s a sign that it might be better to just stick to the basic setup and work through the questions.
Hope this helps! Feel free to ask any further questions that you might have.

Hi @tomfogarty2000,
This game is restrictive enough that it does make sense to consider all the possible scenarios.
G H J S T U
J > H S > U G _ _ S > U J = 1 v 3
Since J can only be 1st or 3d, it leaves us with three possible options:
