Would you both expand your solution as I am not able to understand the logic. For example, what are your strong inferences?

if (6) r1c3 is true then (6) r4c3 is false
if (6) r1c3 is false then (2) r1c3 is true and (2) r8c3 is false. Then to avoid the DP, one of the 6's at r6c1 or r6c3 must be true, making the 6 at r4c3 false.
