My solver is down while I debug the chain() routine, so I worked my way through this puzzle with the help of Simple Sudoku. My contribution to the solution should be obvious.
| Code: | after X-Wing on <7> and Colors/Skyscraper on <3>

| *489 2 *479+3 | *78 139 149 | *489 6 5 |

# 45 eliminations remain
<4789> in [band 3] => r9c3=3
Colors/Kite => r8c6<>9

That was one of the most enjoyable puzzles I've played in a while, even though I may have overcomplicated things.
X-Wing (7), didn't seem to do much
Fin Transport; r8c9<>3 did a lot of damage
W-Wing (39) in r3c2 and r8c5 using three SL's on 9; r8c2<>3
Simple Coloring; r8c6<>9 |

Very nice Type 1 uniqueness pattern, aka pMUG+1. |

my favorite pattern two chained strong links to same cell.
(3)r1c9=(3)r1c3-(3)r7c3=(3)r7c8-(3)r3c8=(3)r1c9 => r1c9=3
