GM blitz fun

This is magic. You come home, boot up your laptop, open ICC (www.chessclub.com) and there it is, a grandmaster accepting challenges in your rating zone. So you click on the challenge quickly before someone beats you to it because free games against GMs are rare. 

​I lost the first 3 0 blitz game but came back nicely after my 2500-rated opponent made some big mistakes. Normally I wouldn't show a game like this but there is a mate at the end. That makes it fun.
