I used the 24 UR* in R23C25, notice that the 24 UR contains an x-wing on <2>, so the <4>'s in R23C2 can be eliminated (otherwise we have a 24 DP), which
solves the puzzle.

Another one step solution is the w-wing on <48> with pincers at r3c3 and r9c1, and a strong link on <4> in r5. The <8> at r9c1 is transported to r5c4 via r7c2 => r7c6 => r5c6 which deletes the <8> at r3c4.

a and b are a W-wing with strong link @. Coloring bcd, you can eliminate <1> in three cells as shown, solving the puzzle.
In the above there are also two UR's and a swordfish on <3>.

There is a m-wing: (1)r2c1=r9c4 via (4):r9c1=r9c7.
It immediately removes 1 from r2c4, which also solves the puzzle. |
