53.Q(2,11)+

What strikes me "statistically": White made 35 moves with a Queen, Black only one Queen-Move. White had 21 moves with check, Black only one with check. White took complete control in the second half of the game with the queens and practically only made moves with the queens. In the first half of the game there were at least two big blunders: Black ...15.Bx(6,2)+ loses the green queen. And the (only?) big blunder of White was 18.Q(7,11)+, but Black did not see ...19. HxQ(7,11).

I think black-side (green red) made some inaccurate moves prior to move 15.

I'm not sure if 7...H(7,10) was an ideal move. Yellow was already moving a queen to the "backyard" but the hawk move doesn't do anything for defense. It doesn't block lines to the king, and pieces that it does block are already defended.

I'm not 100% sure, but I think that flank attacks (or backyard attacks) should be able to be defended. But it can get really complicated fast. And I could be wrong. Also, if backyard attacks are effective, would that mean that defending a backyard attack by a counter-backyard attack is a sound strategy??? This is complicated!!!😨

Green probably should have prevented red from developing his queen too far along the diagonal with a move like 3...C(-1, 6). Preventing and developing at the same time. 

I like Martin's idea with ...3.C(-1,6). But perhaps vickalan had an important strategic idea and a counter-backyard attack would be a possible answer, e.g. with ...3.Q(-17,29). But I have no idea what happens if the fight doesn't take place in the center but is moved completely and on both sides to the backyards. Zoom-out then becomes very important in order to keep the overview.
