Beating a much higher rated player...kind of

This is the game from this discussion:

http://www.chess.com/forum/view/community/is-this-immoral?page=1

I would like some analysis on it. I make mistakes a few times in the opening (that have since been corrected), but he makes more.

Check the move list for some variations. At the beginning of the game my opponent was rated 2077 and I 1270

This is only 3 moves...

Yea I messed up. Check the move list for the rest of the game.

Yea in the link I posted Chess.com and I had a huge discussion (65 comments) on this player's exploitation of lower-rated players to obtain his high rating. Hence the "...kind of"

lol the guy you beat.. its pretty sad.. look

Standard Current: 1878 Highest: 2233 (5 Jul 2009)

Avg. Opp.: 1026

Best Win: 1670 (adj)

Today's Rank: #2063 of 70,033 (97.1%)

Total Games: 835 Won: 828 (99%) Lost: 6 (1%) Drawn: 1 (0%)

so he plays all 1000 technically :/, he goes for  rating only :o

but he tends to beat 1500+

and your 1200 so congrats :D

No, the 1670 was a win on time. We had a verrrrrrrrrrrrrry long discussion on it lol.

Though I do think this was a good game, so I posted it.

You have and 'endgame' shortcut (']]') on move 3, which is why it doesn't skip to 4.

Anyway, you analyze yourself too hard. For a player in the 1300s, you have great tactics, and considerable forsight. (Not to mention you play the Sicilian, which I love)

Your opponent plays 1000s, and he plays his endgames like one. His opening was just short of ridiculous, and his middle-game may have drawn against a 1200. All in all, he is quite bad, and you are good. His knight moves were an abomination, and might have ruined the game for him.

The only thing I don't agree with is 3..e5. This creates a bad pawn structure which opens a nice knight stronghold and renders the dark bishop almost useless. Nf6 is actually the 'best' book move, so you played it quite right.

Mosqutip:

Thanks. Kind of unrelated, but I received such an idea from the push to e5 in the KID (which I play often). Why is it necessary there and not here?

I cant quite agree with that 5..Be7 was bad in any way, or worse than the idea of fianchettoing that bishop. I do not think Bishop would have been more active at g7. 14..f4 from you was a positional blunder. Your comment on possible 16..Rxf6 was not accurate, as it just hangs the pawn at e5.

23..Rcd6 really was forced as 23..Nxe1 would have allowed d5 taken with a check.

From here on, you really did a nice job gradually increasing your advantage.

I don't know the King's Indian too well (I avoid dragon-type openings, mostly) but this opening is different because 1. the bishop isn't blocked in, being on the g-file and 2. white's pawn structure is different.

Oh, I think I can answer the question about the difference between the kid and this position with e5. 

In the kid the e5 push is beneficial when there is another pawn that replaces the e5 pawn(generally the f4 pawn) which forces the f6 knight to retreat to a poor square. 

good work, its funny he'll have to beat like 150 players of rating 1000 to get back up? gold.

Good job dude, a very nice win over a player whose rating was gained rather dishonestly.

Here's some analysis:

3... Nf6 isn't quite as accurate as Nc6.

4. Be2 equality already given to you by White.

I don't really like 4... e5, but Rybka calls it best, so... hey. I'm just paranoid about that d5 hole. With your plan later it doesn't appear to be useful to White since YOU occupy it instead! :)

h3 and a3 from your opponent show his lack of a plan. 8... d5! is great, that's quite a high-level plan for you to come up with and it's definitely the best move.

His Bd2 and Nh2 maneuvers once again demonstrate lack of a plan. f5! is once again best, making Nh2 pointless. Nh2 isn't really bad enough to be a mistake; Rybka says Black is better by 0.22 by this point.

Nf1 is an inaccuracy again. For the last 6 or 7 moves White has missed Nxd5 to get rid of the knight. It would have been better than most of his moves. But surprisingly f4? = since the N can return to h2 with equality! Your opponent doesn't pick up on that, obviously.

16... Rxf6 would be better, you're correct. After Nh2 again, White is a tiny bit better. However after Bxg4 Bxg4 your 0.2 advantage is back.

However, that goes away AGAIN - Rc6 is bad after c3 Ne6 dxc4 Nb6 (after Rxc4 White wins a pawn anyway with Qe2 Rc6 Qxe5). Once again your opponent misses it, returning equality.

Good tactical shot with Nc2. But you made a mistake in the annotations; Nxe1?? is quite bad: Nxe1?? Bxd5+ Kh8 (taking is worse by 1.2) Rxe1 White is much better. Defending the knight IS forced.

26... a5?! is actually inaccurate; better is Qe6 to get the Rooks off of defensive duty. Once again, your opponent's response gives it back plus interest. Kh8 is not so good since the King should remain towards the middle for the endgame; once again your opponent hands it back with the silly Kg1. Qg5 is best. Nf6 is best.

30. Rc3? is horrible since now the dark-square Bishop is hopeless. h5 isn't best but it isn't terrible; the knight/bishop trade is better.

32... Qxd2 works but Qxg3 is better - follows Kxg3 Nxe4 dxe4 Rxd2 -+ and the queens are off the board too. After all this his position gets pathetic.

... Nxe4 is good, but you miss a forced mate after dxe4?? Rf7! mate in 8. On your next move Rf8 is forced mate again. This isn't such a big deal with your advantage. After all this, the last group of moves shows no major errors, neither one missed any tactics or draw swindles.

Nicely done!

I do not see it, what does Black have to justify this pawn sacrifise?

Your annotation in response to 3...Nf6: "Mistake, should be precede by ...e5 to prevent 4.e5"

That isn't a mistake. That's actually the most popular move. Why would you be afraid of 4. e5 anyways?

It's sort of a complicated line; I ran it through again and Rxe5 is about =. Looks like Black has enough piece activity to win back the pawn over a few moves.

I find that hard to believe.. What is the continuation from there that your engine gives as the best for Black?  Black does have better piece activity and an advantage of space, but doesnt look like White really has any weak pawns to target to win material back. Plus Qxf6 keeps the same piece activity + space advantage without handing in the pawn.

I think his question was: why should black play e5 in the KID and not here?

Alright, I might not have been getting the right analysis the first time; I tried it again, and Black is simply down a pawn. He can bully the Rook around a bit but he can't make real threats that win back a pawn.
