Sudoku puzzle (Evil 2) has two alternate solutions. When all cells are solved excepting B2 B3 and F2 F3 the candidates for each of those four cells are 2 & 6 respectively.

SOLUTION:
Row A = 1,9,5,7,4,2,6,3,8
Row B = 3,2/6,2/6,9,5,8,7,4,1
Row C = 7,4,8,6,3,1,9,5,2
Row D = 9,3,7,4,1,5,2,8,6
Row E = 5,8,1,2,7,6,4,9,3
Row F = 4,2/6,2/6,8,9,3,1,7,5
Row G = 6,5,9,3,2,4,8,1,7
Row H = 8,7,3,1,6,9,5,2,4
Row J = 2,1,4,5,8,7,3,6,9

Great Sudoku solver!

Faulty advice

This advice is flawed as it shows a true x wing at 5 minutes 38 seconds and says it is not. X wings apply to columns or rows and the example the show has only 2 7's in each column therefore the 7's they circle are the ones that can be removed. I would suggest people take more care in giving advice.
