Star Battle Puzzle - Need Advanced Help
This is 1star version of star battle puzzle and i tried to finish the straightforward moves and placed the Xs as shown in the 1st image.
Then i applied for an advanced trick (thanks to Ok_Job_9417, Colin-Grussing, Material_Wallaby_692 and Mamuschkaa who helped to explain this trick) to add more Xs as shown in the 2nd image.
Then I am stuck at the stage shown in image 3. What would be your next move to eliminate the grids.
If you make detailed comments for the solution, i will be appreciated. Thanks in advance...
