My initial pass of three steps involved cell r2c5 and suggested the following one step Kraken.
Kraken cell (4569)r2c5
(4)r2c5-(4=6)r3c6; r2c6,r3c2<>6
(5)r2c5-(5=6)r2c3; r2c6,r3c2<>6
(6)r2c5*-r89c5=r8c6-r8c3=(6)r2c3; r2c6*,r3c2<>6
(9)r2c5-(9=3)r6c5-r6c3-r6c3=r5c1-(3=6)r9c1- r8c3=(6)r2c3; r2c6,r3c2<>6
