Ignoring the UR Type 4, the <27> UR r25c13 contains a critical elimination. (from my solver)

[Edit: I should have indicated there were multiple UR eliminations that would each crack the UR. I just saw it as one scenario.]

The 2 in r2c1 can immediately be eliminated,
because it implies 7r2c3, 2r5c3, and - through 5r6c3 - also 7r5c1, which gives a deadly pattern.
