Play online chess |  Subject: "Perpetual" Checks & 3 Time Reps
Message:
I was wondering if anyone has a game(s) that were drawn by a so-called "perpetual check"? I say so-called, because actually the draw claim is awarded for the position repeating 3 times ... but still there are repetition draws where it is because a King can be forcibly made to repeat moves 3 times ... or forever. And I'm interested in seeing some of those. The true Perpetuals.
Also however, I would be interested to see 3 times repetition draws that are not actual "perpetual" in nature as well, since the latter are a seldom thing. And I wonder just how often the first does occur compared to the second way? And I believe that both will most likely be of a forcing nature most often, but am not sure of that. Sometimes it is a mutual albeit unspoken decision as well. A silent agreement you might say. So do wonder how frequent that is as well. And to see the type positions where it occurs. (For eg Ive had it happen that we both liked the other players position better than our own. Perhaps one player prefers the others activity, but the other prefers an extra pawn held by the first!? Or such)
***
So please post any perpetual or 3 Time Repetition DRAWS that you are willing to share.

Thanks! }8-)

Play online chess | One True "Perpetual" ...
Message:
Here is one repetition draw that I had long ago in an otb game, which I would like to share because I think it has potential to show up in your games as well, since I saw it occur again in someone else's after my own. When it happened for me, I was indeed down material during a time scramble. But it could just as well occur when things are more even, but a draw is desired.
***
WT has Kh1, Rg1 and Qh2 (note it could just as well be 2 Rooks there rather than one being a Queen ... but the fact that one is a Queen makes it all the more potent a maneuver!)
BL just played Qf3+ !
Now note that BL can always give check by Qf3, Qh5, or Qd1 no matter how WT attempts to rearrange his pieces. No matter whether he has Qg1,Qg2 or Qh2 nor whether Rg1, Rg2, or Rh2. In any combination of that the two pieces can arrive at.
No matter. The fact remains that the King will always be stuck upon h1, where a check can always be given. A true "Perpetual" Check.
***
(Note however, that if the BL King would happen to be in the wrong place, it could ruin everything...if the position were such that one of WT's interposing moves made the BL Queen become pinned to his King. For instance if he had K on the h1-a8 diagonal and so WT could now answer the Qf3+ with Qg2. Thus would end BL's
try to draw, instantly! So, also if it were King upon the a1-h1 rank or h1-h8 file. )
***
Has anyone had this Perpetual, or similar with King trapped to the corner?

I dont have any such examples...
but I have often wondered if there are unforced perpetuals in some openings?... i.e. imagine the scenario where white moves a piece somewhere... say he moves his bishop out, then the black player moves his queen to attack the pawn the bishop defended... so white plays the bishop back... Black not wanting his queen out retreats it, black doesn't neccessarily want the draw, but cannot allow the bishop to come out to such a strong position, thus feels he HAS to keep showing white that he cant make this move... white persists with his strong bishop move and the game will be drawn....
Ok probably not a great example, buts its an example of a positional struggle that could happen anytime, and unless somebody backs down it will draw...
I think if somebody has a good database and good query skills ( not me ), you might find find such positions where the position repeats twice yet white backs out at the last minute and seeks a win... these ought to be interesting positions.

Modern Chess Players Prove Bobby Fischer Was Wrong — Bobby Fischer once famously remarked that "chess is dead". What he meant was that so much had been discovered about the game of chess that creativity and innovation were waning. Chess players are certainly better prepared than ever because databases and computers are widely used to analyze and dissect openings. Players can sometimes reel off 20 or more moves before they leave their preparation. That seems to have sucked the life out of some chess openings. Most top players know a couple of lines in the Petroff Defense through more than 20 moves, and it is not uncommon for them to play that out and agree to a draw, if that is the result they want. But there are ...

I can give an example of the top of my head. Here it goes: 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Bf4 Bg7 5.e3 c5 6.dc Qa5 7.cd Nd5 8.Qd5 Bc3 9.bc Qc3 10.Ke2 Qa1 11.Be5 Qc1 (I should mention that if Black wants more than half a point he can play Qb1, but it involves some pretty bik risks) 12.Bh8 Be6 13.Qb7 Qc2 with a perpetual. White cannot evoid the perpetual or he'll get mated on g4 and Black is too much material down to do anything else.

Vlad Kramnik and Magnus Carlsen go toe-to-toe at Wijk aan Zee — Corus Wijk aan Zee, the most popular event on the chess calendar, ends tomorrow with ex-champion Vlad Kramnik and the world No1 Magnus Carlsen competing for the lead in the closing rounds. Kramnik won their individual game impressively, but the 19-year-old Norwegian has the easier finish. Carlsen is not yet dominating his chess peers in the style of Bobby Fischer and Garry Kasparov at their peaks, but he is already the man to beat. The reigning world chess champion Vishy Anand has played an uncharacteristically low-key tournament, drawing his first nine games. Nigel Short, in his strongest event for years, has struggled in some games but missed a clear win against Kramnik. ...

I've just remembered a third game that ended in a repeat. I'll send you that one another time. It's a fairly interesting game too, but I did stuff up my attack...

Vladimir Kramnik edges ahead — Vishy Anand may have taken Vladimir Kramnik’s world title but he did him a favour in tenth round at Corus chess tournament when he broke his run of nine draws and defeated the co-leader Alexey Shirov. It was Shirov’s first defeat and Kramnik’s nervy draw with Vassily Ivanchuk gave him the sole lead on 7/10 with three to play but as well as Shirov he has world number one Magnus Carlsen in hot pursuit. Carlsen defeated Sergey Karjakin in what your correspondent found a mystifying game in which Karjakin, playing white seemed to have the initiative and better placed pieces but was soon worse. So the chess tournament is set up perfectly for ...

...what the other 'repetition' is you're asking for, Craig: an 'unforced' 3-fold repetition (a kind of tacit agreement to draw, not necessarily involving a series of checks), or the situation in which the defender can hold off repetition for quite some time, but will sooner or later repeat. This situation illustrates what I mean:
White: Kb1, Qd8, Ps: b2, b3, c2
Black: Kf7, Qc5, Rh8, Ps: a6, b7, d6, e5, g6
White plays 1.Qe7+ and maintains a series of checks along the h4-d8 diagonal. There need be no immediate repetition, but Black can not escape the checks. Sooner or later the position will repeat.
It looks as though one of my currently active games (ionadowman vs efrog1074) will end in similar fashion (a disappointment, really, as I thought until a few moves back I had the better of it...).
The other game:
White: ionadowman
Black: pinkoy
Opening; QGD - a line I'm in no great rush to repeat...

Kramnik claims Carlsen — Vladimir Kramnik played what he described as feeling like “his greatest ever game” to defeat Magnus Carlsen in the ninth round of the Corus chess tournament at Wijk aan Zee. The former world chess champion moved into the joint lead with Alexey Shirov and avenged his defeat at Carlsen’s hands at last December’s London Chess Classic. Scores with four to play: 1-2 Shirov, Kramnik 6.5/9; 3-4 Carlsen, Karjakin 5.5; 5-7 Ivanchuk, Dominguez, Nakamura 5; 8-9 Leko, Anand 4.5; 10 Caruana 3.5; 11-13 Tiviakov, Short, Van Wely 3; 14 Smeets 2.5; ...

Shirov in Sveshnikov — Vladimir Kramnik made his move in the eighth round of the Corus chess tournament at Wijk aan Zee and defeated the US chess champion Hikaru Nakamura to join Magnus Carlsen in second place. Alexey Shirov remains half a point ahead with five to play and he tested Magnus Carlsen’s chess opening preparation by challenging him to repeat the line that decided last year’s MTel tournament when Carlsen lost badly. A fascinating game. In the Sveshnikov Sicilian Black often sacrifices pawns for activity. White is three pawns ahead at the end but cannot coordinate. ...
