I did it by noting the 3 connected 37, so if the one at r2c3 is 7 then r6c8 is also 7 and block 3 has nowhere for a 7 so r2c3 must be 3 stte

All I could see was an Xwing on 3s c27r14 followed by 37-8 XYwing
pivot r2c3 r1c7=3 stte. But I count myself as doing well if I can see any
solution these days......
