I initially found the W-wing 49, but then noticed that Leren had already posted that solution so I located an alternate.....

9r1c5=(9-1)r2c5=r9c5-ALS(1369)r9c489[1r9c48=9r9c8]-(9=6)r1c8-(6=47)r1c62 => r1c5<>4

m-wing
(9=4)r1c5-r9c5=(4-9)r9c3=9r9c8 = -9r1c8


I also played the M-Wing, but the other way, with the pincers at r1c8 and r9c3 =>r9c8<>9.
