hi,

Just using the "standard" techniques:

2 not in r2c7 and not in r2c8, it is in r1c7 or r1c8 (Row on 3x3 Block interaction)
7 not in r2c1 and not in r2c3, it is in r1c2 or r1c3 (Row on 3x3 Block interaction)
5 not in r4c3, not in r5c2 and not in r5c3, it is in r6c1 or r6c2 (Row on 3x3 Block interaction)
2 not in r8c2 and not in r8c3, it is in r9c2 or r9c3 (Row on 3x3 Block interaction)
7 not in r7c2, not in r8c2, not in r8c3, not in r9c2 and not in r9c3,
it is in r7c1 or r8c1 or r9c1 (Column on 3x3 Block interaction)
1 not in r3c2 and not in r3c8, Hidden Pair 5 8 in r3c2 and r3c8 (in Row)
3 not in r3c8, Hidden Pair 5 8 in r3c2 and r3c8 (in Row)
9 not in r3c2, Hidden Pair 5 8 in r3c2 and r3c8 (in Row)
5 not in r7c2 and not in r8c2, Nacked Pair 5 8 in r3c2 and r6c2 (same Column)
8 not in r8c2, Nacked Pair 5 8 in r3c2 and r6c2 (same Column)
1 not in r2c3 and not in r8c3, Hidden Pair 5 8 in r2c3 and r8c3 (in Column)
9 not in r2c3 and not in r8c3, Hidden Pair 5 8 in r2c3 and r8c3 (in Column)
