This is a recent correspondence game I played.  I tried to crack the Grunfeld with 5. h4, which I have since abandoned.  I blundered the opening with 10. e5, but kept the game interesting with a faux rook "sacrifice".  I decline to go up an exchange, and instead go down an exchange instead..  In the end, Black secures a draw with a stunning 25... Qb4, which looks pointless, but actually saves Black's hanging rook on a1 and allows Black to save the draw, even at the cost of his g6 pawn - even taking with check, Black is still safe.  Overall, a great game.
