    The silver lining of tariff based economies have been the disasters of a decades long poverty ridden depression in the later part of the XIXth century and th crash of 1929 and subsequent depression that was not an insignificant factor in the political mood that led to WW II. Thanks for wishing us this as a cure to consumers' appetites.
    I don't know if this is meant by algorythms creating those puzzles, but I find it fascinating how frequent solutions depend on, or is facilitated by, potential UR conflicts. So again today, when the puzzle becomes more difficult in the situation you had in the 8th minute of the video, a quick and easy solution driven by a UR potential in the 2nd and 3rd columns of rows 1 and 5. As you identified early, row 5 has a certain 29 pair. Row 9 has a known matching positions in either col 2 or 3. So, already, you know that the 2 cannot join those 9s. We also know that r1c4 is a 24 bi-value cell and that r1c3 and r3c3 are a pair of 8s.
    At that stage, you still cannot immediately solve this. You have easy placements to do like 48 in the middle row of block 6, and hence 1 in r4c9 and 7 in r6c9, 7 in r5c5 and 1 in r6c6, etc. Ultimately, you will know that the 2 and 4 cannot both be in the lower row of block 1 , so one of them will have to join the 9 in the upper row, and the obvious choice will be the 4 due to the UR rule.
    Good puzzle today, but still relatively easy to solve in the end thanks to this UR situation.

      Accusing me of 'wishing' this policy is rather unfair. I certainly don't think it's a good idea, knowing that essential goods and services are likely to be hit, making life especially difficult for the less well off. I merely wondered if an unintended consequence might be reduced consumerism (not that I think that's the right way to achieve it).

      @@zen_art_of_guardian_sudoku I was just being sarcastic, you should know me by now:) The teriff policy gets much more complicated nowadays with extensive industry integration. Canada was told there will be a 25% tariff on all imported goods starting the first day of his presidency. The first step in the production of aluminium occurs in Canada, more precisely Quebec plus one plant in British Columbia. The US has no modern in frastructure for it, and no plant is capable of obtaining a safe, stable electrical power supply to operate their plants, and the cost of electricity would be about 5 times the Quebec cost. So what will happen to the price of aluminium based parts in Boeing aircrafts, American cars. In the latter case, car components may cross the Canada-US border as much as 5 times in the various steps of industrial production before they end up in a auto assembly plant in the US.This is just crazy, and resistance to tariffs will originate as much from inside America as from victimised countries.
      There are strictly no serious economists who think this stupid idea can work. This may not prevent Trump from inflicting much harm within as well as without the US.

    15th minute: you can make so much more progress by simply placing the 3 in r3c5 ! Other flurry of easy placements follow... eg 3 in r4c6 and r6c1

    Not that difficult today. 10 minutes, no pencil marks
