Forcing Chain Contradiction in Row 7 Digit 2:
9r4c4 - (9=6) r6c6 - 6r5c5 = 6r3c5 - 6r13c4 = (6-2) r7c4;
9r4c4 - 9r4c2 = 9r5c3 - (9=2) r2c3 - 2r8c3 = 2r8c8 - 2r7c8; => - 9 r4c4; stte

You can change your forcing chain into a discontinuous loop by writing the second segment from r-to-l and appending it to the first segment.
You can also shorten the first segment by using <6> in [b8].
9r4c4 - (9=6)r6c6 - r79c6 = (6-2)r7c4 = r7c8 - r8c8 = r8c3 - (2=9)r2c3 - r5c3 = r4c2 - 9r4c4 ; stte
Or as an AIC.
(9=6)r6c6 - r79c6 = (6-2)r7c4 = r7c8 - r8c8 = r8c3 - (2=9)r2c3 - r5c3 = 9r4c2 => -9 r4c4 ; stte
