Initially I spotted the Sue de Cue (24568)r1c789 with (68)r1c3 and (247)r2c8|r3c7 which deletes r3c9<>4, r23c9<>7, r1c4<>5, r2c9<>5

However, this step did not complete the puzzle. A simple xy-wing(18-2)r2c9 with pseudocell pincer (28) in r7c89 did the deed:
(2=1)r2c5-(1=86)r27c9-(6=2)r7c8 => r2c8<>2

Given the insight from this two step solution, I tried again and found this long single chain that makes the identical deletion to complete the puzzle in one step.

2r2c45=2r2c8-(2=68)r7c89-8r12c9=8r1c7-(8=6)r1c3-6r1c89=(6-1)r3c9=1r2c9-(1=2)r2c5 => r2c8<>2

Fun puzzle... :D
