Jan-11-09  WhiteRook48: this is such a long game, but the longest is 275 moves.
Jan-22-09  WhiteRook48: well, he would've ended up with KQ vs K, but imagine if Black played on until checkmate.
Jan-24-09  WhiteRook48: 193 moves!! Wow!!
Jan-25-09  WhiteRook48: 163. ...Bxf4? In theory, Mashian made a mistake by trading when he was behind in material...
Jan-25-09  WhiteRook48: oh no! Black resigned instead of playing his 193rd move!!
Jan-31-09  WhiteRook48: why not 193...Kg2
Feb-02-09  WhiteRook48: why didn't he save his knight?
Feb-02-09  Gilmoy: <WhiteRook48:> The Knight can run, but it can't get away. After 57..Nb8 58.Bxf6+ Kg8 59.Bd8 White traps the Knight with Bb5 and Bc7, and then queens the a-pawn. Black was correct to give up the Knight to prevent White's DSB from getting behind his pawns.
Feb-04-09  WhiteRook48: they were so tired after this game, I imagine
Feb-07-09  WhiteRook48: thanks for analysis
Feb-07-09  WhiteRook48: how frustrating for Black!
<163...Bxf4? Don't trade when you're behind in material> Never mind that, maybe Black wanted to get rid of white's bishop pair
Feb-07-09  WhiteRook48: 177...c2 practically forces the sac
Feb-14-09  WhiteRook48: <why not 193...Kg2> Never mind, 193. Ke8 wins
Feb-20-09  WhiteRook48: wait, all the pawns were remaining for 44 moves!!
Sep-12-09  SgtPepper: Actually, the rule for achieving a draw is 5O moves without taking a piece AND moving a pawn.

<2021> No, the longest game without a draw (not counting computer games) was Fressinet vs. Kosteniuk, 2007 (237 moves). Kosteniuk won, but Fressinet could have claimed a draw by the 50-move rule.

<SadisticKing>, the 50-move rule did not come up in this game. From White's 94th move to White's 131st move is only 37 moves. All other series of reversible moves were even shorter.

If they continue from the final position:
193 Ke6 Qg6+ (or Qh6+) 194 Qf6+ Qxf6+ 195 Kxf6 Ke3 196 Ke5 Ke2 197 Kd4 Kf2 198 f8Q+ Kg3 199 Ke4 Kg2 200 Qf3+ Kg1 201 Qe2 Kh1 202 Kf3 Kg1 203 Qg2#

193 Ke6 Kg2 194 f8Q Qg6+ 195 Ke7 Qh7+ 196 Kf6 Qh4+ 197 Qg5+ Qxg5+ 198 Kxg5 Kg3 199 Qf4+ Kh3 200 Qg4+ Kh2 201 Kf4 Kh1 202 Kf3 Kh2 203 Qg2#

Oct-25-10  sevenseaman: Its a theoretical drawing board for an end game. Good of Cg to have included it.
Jun-01-11  kevins55555: ♕♙ vs ♕ endings are hard for the ♕ only side because the ♕ has to keep checking or else the pawn's going to promote and the ♕♕ side will trade off the final ♕ of the defending side and force a queen checkmate. LOL
Feb-22-15  morfishine: "Stepak's Immortal"
Jul-08-17  Duracell: Record for the longest decisive game, not online and not blitz, is Danin-Azarov 2016, 239 moves, not yet in this site!
May-11-19  N.O.F. NAJDORF: Yes.

Black, who three times represented Iran in chess Olympiads, missed a draw on move 136 simply by claiming one!

I think he may also have missed a draw by 133 ... Bd2.

May-11-19  N.O.F. NAJDORF: Unless I am mistaken, black could still have claimed a draw as late as move 163.
May-11-19  N.O.F. NAJDORF: This game has a much more attractive finish:

Y Stepak vs N Spiridonov, 1966

Jan-24-20  N.O.F. NAJDORF: 'the 50-move rule did not come up in this game.'

Yes - you're right!

I completely miscalculated.
