i tried to understand the van Wely blunder a little better. i looked for some kind of explanation that would make his blunder seem more justified. i felt sorry for van Wely. Does anyone know if van Wely is having health problems? i could not find anything that would make me feel better about this blunder. this was a mate in 4 blunder, on long time control with a 2697 Grandmaster. I do not understand these blunders. i have been told over and over that the GM has a sense about the board position like no other human has. it is difficult to comprehend this blunder, when other GM's are playing and winning blindfolded. at this site Loek Van Wely is ranked 16 in the world. http://www.fide.com/cgi-bin/base.cgi?search_name=&search_country=-1&search_sex=-1&search_rating_min=&search_rating_max= these GM blunders are hard for me to understand, especially this one. i thought Van Wely was hoping Morozevich would take the queen after Qc5. but this also would not help the position. i do not understand why van Wely did not just resign, instead of this blunder. some here have already told me that GM are allowed to blunder. i do not expect a perfect GM game from e4. but i do not except a blunder from a high raking GM in a standard game.
