Jan-04-09  PhilipofBrazza: I was saddened to learn of IM Mark Diesen's recent premature death, not because I knew him personally (I didn't), but because I knew of him as a chess player, and, more significantly for me, I happen to have played an amusing 3-minute blitz game with him on ICC only 4 months ago (below; game 72 of my personal library, "liblist PhilipofBrazza" on that site)!

Playing through some of his games, one can sense what a powerful positional player he was. May he rest in peace.

Jan-05-09  Maynard5: Everyone who knew IM Mark Diesen will be saddened to hear of his premature death, at age 51.

I first met Mark in Philadelphia, 1974, during the U.S. Junior Championship. Only 16 at the time, he was already a very strong player, rated over 2300. He was also friendly, affable, and a very upbeat, optimistic person, with an infectious enthusiasm for the game. While he only finished fourth that year, he went on to place second in 1975, and share first place in 1976. In 1976, he also won the World Junior Championship, and was awarded the IM title.

There has been some speculation as to why he did not continue in chess. As he put it himself, chess was his first love, but the economics just weren’t there. Instead, he went on to a successful second career in chemical engineering. He lived in Texas, in the suburbs of Houston, with his wife and three daughters. He continued to follow the world of chess, even though he was no longer playing actively.

Perhaps the best way to commemorate Mark would be to replay his fine games on this website. He had several impressive victories, notably against Walter Browne and Michael Rohde. Mark loved chess, and this is the way that he would have wanted to be remembered.

Jan-05-09  jackpawn: Mark was obviously GM strength by the late 70's. Look at his game with Korchnoi, drawing easily with black.

His premature death is yet another reminder to live life for today, as my wife often reminds me.

May Mark rest in peace.

Jan-05-09  biglo: His ICC finger notes say "several GM norms Karlovac 77' Polaniza Zdroj '78 etc"
Jan-07-09  Danya: what did he die from?

There have to be a way, to work Diesen Sphere into a pun and be the game of the day...

Any other member care to help out with this pun?

  LIFE Master AJ: I read on another page, (Chessgames Challenge: M Umansky vs The World, 2009); that Mark Diesen had passed away.

I started leaking, (tears) ... I don't even know why. (We were not close friends.) In a way, it was kind of dumb, I am not even sure that I understand why I was so upset.

He defeated me at the Louisiana State Championships one year. I honestly wish I had the game, I would post it.

Anyway, I had to do something. So here are a few links to commemorate a fine chess player ... who died way too soon.

Jan-12-10  Caissanist: <Mark was obviously GM strength by the late 70's> Many top US players of the seventies were probably GM strength but never got the GM title, since at the time there were very few US tournaments where you could get GM norms. Besides Diesen, these included Kim Commons, Norman Weinstein, Sal Matera and John Peters. Even Jim Tarjan (at one time the #2 player in the country) had to move to Yugoslavia for six months to get his title.
Feb-22-11  wordfunph: British newspapers once carried headlines like this one: "Another Bobby Fischer on the Horizon!" referring to American schoolboy 16 y.o. Mark Diesen who won the 60-player swiss-type 1974 Hastings Challengers with 6 wins and 4 draws.

rest in peace IM Mark Diesen..

  FSR: He was on the Free Internet Chess Server one time, and I "spoke" with him briefly. I told him of my line "Mark is a Diesen player" and he was polite enough to claim to find it funny. He offered to play me a game, but I was too wimpy. (Pretty pathetic, to be sure. Oh no, if I play this IM a blitz game on the Internet, he'll probably crush me and bruise my fragile ego!)
Mar-13-12  esundel: <Strongest Force>, i used to know mark back in the day when we were both kids. it is a really great pity he passed on. he was really amazing at the game ( 2350 when i was 1800). i i would be interested in getting touch with some of my old chess friends. <Strongest Force> please email me at esundel56@yahoo.com. maybe we knew each other back in the day, and it would be nice to talk about old memories.

  perfidious: <Caissanist: Many top US players of the seventies were probably GM strength but never got the GM title, since at the time there were very few US tournaments where you could get GM norms....>

The only chance a typical strong young American had was the odd invitational-even then, the time limit (believe norms expired after three years in those days) placed a well-nigh insuperable burden on any American unwilling or unable to play in Europe.

<....Besides Diesen, these included Kim Commons, Norman Weinstein, Sal Matera and John Peters....>

All except Peters eventually found more stability outside the world of chess; in my opinion, all the above-named players would have eventually made GM had they carried on playing.

Aug-07-19  Caissanist: IM Mark Ginsburg annotates a bunch of Diesen games, in a pair of articles published shortly after Diesen's death:

http://www.uschess.org/content/view...
http://www.uschess.org/content/view...

Sep-17-21  Ironmanth: Learning and playing chess in the seventies in the Washington D.C. metro area, the name of Mark Diesen was a vaunted one. I recall reading that like me, he played the 3M Bookshelf game "Twixt". The article claimed he analyzed it so deeply that he could not lose, and I believed it. Sadly, this very strong player was taken too early. RIP Mark Diesen - you were so respected.
Sep-18-21  rbhgroup: I also met Mark in the Washington D.C. area, around 1970 or so... he was a great chess talent, of course, but also a very enjoyable person to be around, and very approachable. The world needs more people like him. R.I.P.
