Same rules. Hopefully, it won't be excessively difficult.

Code:

not excessively, no.

UR (27) type 1: r1c3=8
coloring (2): r1c8<>2
w-wing (6)r3c2=r9c1 (SL 7 in col 3); r123c1<>6 thus r3c2=6

UR on {27} r12c35

leads to

extended W-wing on {27} eliminates 2 in r1c9
(2)r1c5=(2)r2c5-(2)r2c3=(2)r4c3-(2=7)r5c1-(7)r9c1=(7)r9c7-(7=2)r7c9; r1c9 <> 2

leads to xy-chain, 27-27-28-28- which eliminates the 2 in r3c7
