I also would like to know if you start up a game.
I think this is a good initiative, it helps understand a lot of thoughts behind the moves.
If this were a tournament game, or one where the loser buys the beer, then playing Qc7 would leave Black no choice but to initiate the perpetual checks and force the game into a Draw situation.
I have been in a number of games where I had a clear upper hand, only to have my opponent force the game into a Draw. It almost felt like a loss, because I allowed my opponent to escape when I was so close to victory. We all watch out for that accidental Stalemate situation, but what about the one where your opponent can thwart your victory by forcing a Draw.
As long as @zrylam has his Queen lurking just above my King, he has that option of forcing a Draw. Now that I have played Qc3, I have eliminated that possibility. The only thing that can happen now is that we exchange Queens if he puts my King in check.
