Re: I was right!

So, to be clear, which exactly was the move that messed with Kasparov's mind? 44. ... Rxd1 - it was an inconsequential move in the game, DB literally play this move at random , but it planted the seed of doubt in Kasparov's mind While that was the move attributed to a bug, the one that really cause...

Re: I was right!

On one level, the DB win was the worst thing that ever happen to computer chess. DB would not even be close to today's top engines with today' hardware. But at the time , there was nothing else close to it. Why did IBM have to take the machine apart? I never understood that, DB should have gone rig...

Re: Lee Se-dol retires in face of AI...

I wonder if the relentless advance of the machine was a factor in Gary Kasparov's retirement? My recollection is that it had a lot to do with the lack of a proper candidates system at the time to determine the next challenger. Wikipedia: "He cited as the reason a lack of personal goals in the chess...

Re: World Fischer Random Championship

So Wesley So becomes the World champion by an incredible score of 13.5 to 2.5 over Magnus Carlsen.. That is incredible ! Agreed. Note: For those who don't know, the scoring was weighted such that the 45/40 + SD/15min games were worth 3 points, the 15+2 games were worth 2 points, and the blitz 3+2 (...

Re: World Fischer Random Championship

Our Normal chess is position #518 in Chess960, also notice that playing our Normal Standard Chess Position in Chess960 the Castling is done differently watch this video carefully, you can NOT castle by simply picking up the King and dropping it on the g square, you have to drop the King on top of t...

Re: is this a fortress?

I don't see the fortress, it seems to me that back can force a pawn off the board, either a or b pawn or the g4 pawn and once a white pawn comes off , it's over. Agreed, though it's less about the a-pawn than the g-pawn. Once black installs its own pawn on g4, the standard f3 fortress square is gon...

Re: is this a fortress?

OK, I'm coming around to this not being a fortress. :) I played a couple games against SF 8 from this position, attempting to use f3 and/or e3 for the rook and keeping the queenside steady with a4 and b3 pawns and the knight on c4. Unfortunately, the queen was able to force some zugzwangs to win the...

Re: is this a fortress?

It seems easy for white to hold a draw here. But why do you even think black is better? Probably white should play for a win here. But black is lucky that the white KIng is susceptile to perpetual check. I agree with you. During the game, I was worried my opponent (white) would defend in this way a...

is this a fortress?

Some weekends ago, I played a game as black where my opponent had a chance to defend my attack by trading a queen and pawn for two rooks to reach this position: 3k4/2p3pp/5p2/8/2N3P1/PP3RP1/2q3PK/8 b - - 0 34 During the game, I felt this would be a fortress since even if the rook can be pushed off t...
