I haven't been able to work on a puzzle for a couple of days and just got carried away with this one..............

axy-wing(49-7(r4c9+r2c9|r6c7 & fin(2)r2c9 plus two transport
[(7)r8c7=(7)r89c9-(7=9)r2c9-(9=4)r4c9-(4=7)r6c7]=(*2)r2c9-(2=47)r89c9-(4)r78c7=r6c7-(4=7)r6c3-(7=9)r5c3-(9=45)r48c1-(5)r9c1=(5-9)r9c6=r9c4-(9=2)r1c4-(2)r1c1 => Conflict: No 2s in box1; r2c9<>2, r235<>7

Another deletion is possible:
Code:

(7)r6c7-r8c7=r89c9-r2c9 \
      \                  r3c8=7-r3c45=(7)r2c4; r8c4<>7
       -r23c7           /

I tried marking the code grid but it was too messy.

I seem to be in a "long chain" mode today.........

(6=4)r7c5-r7c2=r3c2-r3c45=(4-7)r2c4=r3c45-r3c8=r5c8-(7=9)r5c3-(9=45)r48c1-(45=6)r9c1; r9c5<>6

Code:
r9c5=7 -> r9c9=4 -> r6c7=4
r3c5=7 -> r5c8=7 => r6c7<>7

Shorter chains?
