Mar-09-10  HeMateMe: Well, that sounds looney. I can understand a few errors in changing from descriptive to algebraic notation, but moving whole junks of material? Seems hard to believe.

I don't see this book on any shelves, at Borders, Dalton, or BN books. But, I'll take your word for it.

Mar-12-10  Ryan Razo: Sorry, I have no credit card, buddy. Can't buy that on eBay with nothing.

... But I really needed a copy of Herr Nimzo's "My System", BADLY. :)

May-14-10  JohnBoy: Surely ChessGames can come up with a picture of Dif. And, on an aside, there was a great contest between Dif & Christiansen in about '75 at the American Open. Dif was white. Totally crushing LC. Then got cheapo'd in the ending. Anyone have the game score and can submit it to ChessGames?

  Landman: "If you're a GM you should be able to overpower the IM tactically. The GM will often blow out the IM in this area." --- Nick de Firmian

In one of the middle rounds at the 1986 World Open, Canadian IM Byron Nickoloff was White against de Firmian. It was a complicated Sicilian middlegame with open lines in the center. de Firmian's King was safely castled behind pawns on f7,g7, and h7. While de Firmian was thinking, Nickoloff got up and studied the position on the demonstration board. After a while he stepped out for a break, obviously pretty happy with his position. While he was away, de Firmian played g7-g5 to attack Nickoloff's Queen on f4. The pawn right in front of his King. That pawn.

When Nickoloff came back, the move on the demo board stopped him. He looked at it for several minutes.

After a while he sat back down and buried his head in his hands. The move had been a shock to him and a shock to his whole position, which soon collapsed.

As mentioned in the biography here, he went on to win the whole tournament, including wins over Lev Alburt and Yasser Seirawan.

Aug-23-12  Troller: Unless they have split up, this is Nick's girlfriend/wife: Christine Jensen

She is suffering from muscular dystrophy; here is an article in Danish on how this complicated their lives after they had a son in the late 1990's:

Aug-30-12  RMKvdS: <Landman> Can't find the game on nor on chessbase... Just curious, cause I tend to lose games on overlooking the less obvious moves as well!

  Karpova: Q: What was your most embarrassing moment at the chess board?

de Firmian: <When I knocked over my pint of beer against John Nunn in a blitz tournament in Lubeck. That was also painful, because the glass was practically full.>

  PhilFeeley: I'm curious to know why he was listed as Canadian for this year's Canadian Championship:

Did he move? FIDE still lists him as American.
