I have lost in past whenever I have exchanged my Q for 2 rooks.This time it turned out to be different.

2 rooks are stronger than a queen

Why was black king doing disco dance in the end! There are many strong 'queen players' who know how to unleash eve's terror. I think Q vs RR exchange depends upon how well you can use either of them in the end game. Also, breaking rook in rank/file tends to weak them against unprotected king checks.

I think you used the rooks together quite well in the endgame. Thanks for sharing this.

Btw, I thought 51. Re8 was winning as well. Did I miss something?
