the alt code in windows for ü is alt-0252. Hold down the right alt key, and on the keypad press 2, then 5, and then 2, and release the alt key. Look up alt codes, or get a program to do it for you (like the windows language bar) to find out what they all are (although I specifically have memorized ü)
Getting a feel for the Gruenfeld


Lately I have been trying out the Gruenfeld (What's the keystroke for an U umlaut anyway?) and havn't had the greatest success with it. I just can't seem to get a feel for the opening. I make decent moves but I can't seem to make the sharpest or most correct moves in early mid-game. Any good illustrative games or introductions to the opening that show the key ideas associatiated with the open. Or anyone have a spare copy of Yelena Dembo's book on it you wouldn't mind shipping me? :)
