Just a turbot fish. I find them looking at the strong links in one number and trying to connect them with a weak one, eg r1c3-r1c5 and r9c3-r9c6 can be linked with r1c3~r9c3. So you can eliminate 9 from r2c6 and r3c6.
You also can practice to see the "pattern" (turbot fish 4, i think) as nick70 described it
