Ok, i'm proud of myself =) i drew a game with someone rated almost 600 points higher than me! Why is this in endgame study, then, instead of games showcase? Because i'm CERTAIN that I missed a win somewhere. Please tell if you find one, or just comment on other moves you'd've changed. Thanx!=)

 

One footnote for playing a person "stronger" than you, one of the best ways to play is to get a solid position, and take any advantage you opponent give you. It served me well here =)

I think you're right in that your 37th move was the one that lost the win. A good thing to do in those situations, when you have an extra pawn on one side of the board, is to try to keep all of your pawns in line as much as possible.

Still, congratulations for getting a draw against such a higher-rated player. At least you didn't lose...

On move 37 black can not make much progress with his king on the queen side. So you should have tried to penetrate the king side with Kf3 sending your king to f7. This was the winning plan for you.

CPawn

37.f5 wasnt good as it fixed your pawn majority to the white squares, which basically rendered your Kingside advantage and light squared bishop useless.  But beside that, well played.

General-Lee

Thanx all! =)

why'd you give up? =( you had the B v N, 1 pawn up, and a kingside majority. it's a clear win. instead of that random king move at the end you  could have played h3, and made slow progress. at least try >.>

 

solid game though.

Hahahahahahaha! Why'd I give up?! Principle of two weaknesses. My pawns were stuck on light squares and I had no good way to invade. Q-side play was impossible, and in that case the Knight was quite an able defender. I'm sure if I had restrained my patzerly impulses to push the K-side pawns immediately I could've won, but I'll ask Rybka what she thinks Smile

General-Lee

Rybka (after about a half hour analysis) assigns the value of +0.42 to the position (that's +/= in human notation). This is marked superiority, however, >+0.6 is considered "winning" therefore the position is a draw. =)

General-Lee

Why the lol? i mean i know it's cheap to have a computer prove my point for me but oh well =)

Nice game! Also, let me say I understand your being nervous and more easily satisfied with a draw while playing a higher rated player.

This is my idea for a win (which I don't know if I would have found OTB):

White's king infiltrates through h4 after playing 43. Kg3 instead of 43. Ke2. White is not worried about black infiltrating his own camp, b/c the black king is in a prison. He can never infiltrate white's camp. The light squared bishop combines with the pawns to form a total blocade.

So, black's king must race to protect the g7 pawn, which he can only do so from f8 - he gets there just as white's king gets to g6, actually. Black's knight cannot fill this task as he can be forced out from e8 by Bb5. White can force a passed pawn in a couple of ways.. he can play e5, followed by f6, and that should be enough to win. 

The winning idea might be faulty, but I think that because of how black's king can make absolutely no threats of his own due to the blocade then white should be able to win with his extra pawn.

essnov

Oops-- wanted to add: Black can force the white king out of g6 by playing Ne7+, but then white can just break through with h4 and eventually g5 while his king sits on h7. Black temporarily gets a passed g-pawn instead of a passed e-pawn in this variation but it is harmless due to black's awful king position. The g-pawn either stays put and is captured by the white king or runs into bishop city. It's the same principle with the passed e-pawn that black gets in the variation I write about in my previous post.

To be quite honest, I am not sure if I would be confident enough to take this kind of risk OTB, maybe with time pressure, and with a higher rated opponent. ^^;

General-Lee

it was corr. there wasn't any time pressure, but i couldn't find a truly winning plan so i just called a truce =P

lol i'm flattered but this game was one in a million =)

General-Lee

well sir, if it would please you how's about you defend against Rybka when it assigns the position as "winning" and tell me how it goes?Smile no disrespect, cuz u'd crush me in a game, but i doubt you could argue with a 3150 computer's analysis.

YuvalW

I think Bb5 instead of one move in moves 25-27, and trading the bishop for a knight, shold lead to a easier victory, as K+N+P vs K+N with a few more pawns on the board is the second easiest endgame to win (after K+P vs K)

General-Lee

maybe Boring, but the bishop was better (initially) so i wasn't about to trade it off.

try to win up a pawn better u just had to get king to tie down his king and then u win

it's not that simple though. with a knight and bishop plus multiple pawns he had totally defended against my threats.

Not arguing with the comp's analysis...merely with the arbitrary notion that somehow +0.6 represents a clearly "winning" position.  I would say half a pawn up is a clear advantage, but not a win yet.  Also (complicating these situations) is the fact that there are all sorts of different kinds of positions, but computers (being computers) give numerical assessments to one and all.  They might make sense to a comp (indeed, they're the only kind of sense a comp can have) but they're a foreign language to human players.


In a complex middlegame position your case holds water, but in an ending like the one shown it is simply obvious that four tenths of a pawn advantage is not enough to win. I'm not a NM, but in the final position I was capable of recognizing that with best play the game was a draw.

Chessroshi

I'm with tonydal here. A +0.6 is all fine and dandy mathmatically speaking, but for a player who is mortal, and not processing hundreds of thousands of positions per second, a practical application of +0.6 into a 'winning' game is hard to achieve. I think he was just getting a chuckle at how the computer decides what is a winning score. Perhaps the beast has calculated out a mate in 2,346 moves or something, you never know with these awful computer things anymore Cool
