Hooray Hooray Hooray

Hooray Hooray Hooray. 5 hours the battle was, but my patience is not even a single YAK is not overpowered. Consider 3-4 options in most rows and columns is of course the torments of hell and the destiny of the computer. But once I got it, so I think that in General, any crossword solve in the future and it was worth it. Huge respect to the author for the excellent crossword and to those people who solved it faster in a logical way, you have a wonderful brain!
