Forcing Mate

This is one of my favorites brilliant moves, again against my aprenttice.

You can see that i was having a lot of problems about the queen in the other side of the board, but i found thi rook sacrifice that could help me to deal with that checkmate, so first of all i saw the position and find to possible ways: 

1 )First it was just draw because its not possible to win but of course to make a draw repeting moves 3 times

2) There is a checkmate but you need to incorporate more attackers to the position and also making for sure the queen get a betther square

Luckly i view the checkmate after a few moves so i end wining this game ^-^
