Here, in This game, I just saw, that I,m winning! And really won! BUT, after my opponent just resigned, I SAW...well, try to find what I saw and what is It! Have he a draw here? An Amazing position!

 

Pls, look at the position after the 80th move! The last several moves are winning moves....But maybe NOT!

 

 
 Final position, blacks on move
 
 
 
 
 
After my last move, my opponent just resigned the game, and this is correct, cos after 85...Rxh7 he will be checkmate - 89. Ra8+
 
But, Or I,m crazy, or he have a draw here? Can you find the draw move??
