$this->bbcode_second_pass_quote('Narz', '')$this->bbcode_second_pass_quote('Carlhole', '')$this->bbcode_second_pass_quote('pablonite', 'T')hat one took me about 5 minutes of real brain power...


This next one is my favorite. White to move and win.

Image

That's from Reinfeld's 1001 Mates book, I just saw it a few days ago. I was unable to calculate the line until the end but I got the basic idea right. Of course that's not really good enough considering your first move (when you make a move like that you have to see the mate!).


queen x pawn check

king x queen

knight x bishop double check

king h6

knight check...which one? It's far enough along that I have to set a board to see it from there...or will have to think on it a while


edit again:
ok, you push the king into open field, check him again with the night...check him again with a pawn...castle king side into another check...can't see the whole thing quite yet..still working it...but by now you've got the black king severly pinned into the white side of the bord and surrounded...surely you can nail him from there with 2 knights, a bishop, a rook, and two pawns all in play against him

if I were playing this live I would definitely go with it, even without being able to 100% see the outcome...black is so hosed he'll either be checkmated or have to start throwing material back to try and survive

$this->bbcode_second_pass_quote('Narz', '')$this->bbcode_second_pass_quote('pablonite', 'R')eal people - street chess. That's the best chess out there.

Often though, street chess is blitz chess & generally low quality. Don't get me wrong, street chess (in Washington Square park mainly) is a main part of how I got so into chess but most street players are not getting better & would not do well in real tournaments. Maybe I'm just biased though cause blitz isn't my strong suit. :cry:

Couple of new Youtube vids I made :

Endgame Vid #1

Endgame Vid #2

Nice videos Narz, I remember trying to learn more about the endgame - so much of it is book play at highest levels which I remember came as a bit of a suprise to me. The computer is master of the endgame and rarely makes mistakes in the opening for this reason. And for the same reason it rules in blitz chess.

I like the idea of tourney chess but I just wouldn't trust most of the people when you start playing for more than just fun. With all the pocket gadgets out these days it would be hard to keep an eye on everyone for 6 hours stretches.

I like the park, roll out chess board and 5 minutes a side type game. It adds a bit of action to the game. Bobby Fischer was pretty much unbeatable in blitz chess, some of his blitz games are quite amazing when you have time to digest the moves. The best chess book IMO is Bobby Fischer Teaches Chess.

$this->bbcode_second_pass_quote('pablonite', 'H')eh, moving the white Knight to g5 is going to cause all sorts of problems for black who has to start defending against mate. I only see moving the pawn to h6

I missed pawn to g6...The queen sacrafice for sure though - it's a good chess puzzle! :)

Thanks! Yeah, modern computers are demons when it comes to spotting tactics & analyzing endgame positions (especially positions with just pawns & only one or two possible lines).

Yeah, it is a concern for me at those big tournaments. However, I haven't seen any sign of cheating myself (from any of my opponents).

Yeah, I do enjoy street chess, I just like the seriousness of tournament chess. Just you & your opponent (hopefully) and pure quiet & no excuses (noise, environment, etc.). It's hard to get the same level of focus in a park or coffee shop (for me anyway, some are not so distractable & I envy them!)

White to force checkmate.


rook x g7 check

if K-f8 then rook g8 check, Kxr, Q-g2 check, kf8, Q-g7 chk,

if K-h8 then rxh7 check, etc.

edit..you have to sacrifice both rooks to get the job done. the bishop ends up on f6 and the queen on g7 for the mate

rook x g7 check
k-f8
rook g8 check
k x rook
rook g1 check
k-f8
bishop g7 check
k-g8
bishop-f6 check
k-f8
r-g8 check
k X rook
queen- g2 check
k-f8
queen-g7 mate

the closing line on this one gelled when I was driving home just now...

chess puzzles are fun, but to be fair the vast majority of them involve some sort of sacrifice leading to a fork, pin, or mate, so once you get used to looking for those types of combinations they start to get easy.

Unfortunately those scenarios rarely come up in normal play against average players.

It's fun when they do though! I've got about six games saved in my library where I pulled off a brilliant multi-move combination....six games out of ten thousand played.

It's hard to get the same level of focus in a park or coffee shop (for me anyway, some are not so distractable & I envy them!)

When you throw a bit of cash on the line it makes it even more interesting. I'm not a gambling man on games of chance but love playing chess for pocket change. Whenever I'm in a big city I try and hunt down a street player and see what they got.

When I took my game to the next level I specialized. When playing black I would play the Sicilian defense with the dragon variation (g6) where you fianchetto your bishop and castle your in King in there. Statistically speaking, you have the best chance of winning with black this way and you spend much less time in the opening when you get comfortable with some of the variations.

When playing white I would work on counters to the sicilian that usually involve castling to the queen side but forget the names of those lines, it's been awhile.

Just a thought for you if you plan on taking your game up a notch or two because when you get to expert level there won't be many mistakes in the opening anymore. Likewise with the endgame, certain material combinations and positions are book draws or wins which is why you get so many resignations at the highest level, it would be like going through the motions and waiting for a blunder that just ain't gonna happen.
$this->bbcode_second_pass_quote('MD ', 't')hanks but pls post the solution for the last one too

Heh, the more I look at that one the more I think I've seen it or something similiar. I think you're right about herding the King right into the black pieces because you can see forcing the King out of the hole but to do much more in your head is hard. It would be hard to take that chance in a real game though. I would still stick with Ng5 g6...and then look at sacraficing a Knight for a pawn if I was playing for cash :)

The best players in the world don't have a special ability to look at more iterations than the average player, they just know the best current move that leads in the general direction of a win. I've seen a few documentaries on chess, great players can be manufactured now, like Tiger Woods is to golf. They learn how to recognize certain formations and positions easily - I believe one was on a Russian girl and her sister who were trained and are now ranked as masters.

I don't enjoy looking at Kasparov games, they are almost clinical and robot like with few notable exceptions. It's like watching Tiger Woods play golf, predicatable and boring really. The grand age of great and exciting chess was in the 1800's IMO.

White to move and win

I started running the puzzles through the computer because I'm lazy and wanted to see just how humbling things had gotten. I am surprised at how fast it saw the Queen sacrifice!

Found this article, kinda interesting on computers and how to beat them. Good luck :lol:

When faced with a master tactician one should try to avoid open positions, where simplistic strategies of centralisation, and tactical awareness predominate. Openings that tend to lead to 'quiet' positions are to be preferred against computers...

Well if the board is upside down then yes, black is mated. no move necessary

Heh, I don't get it. The comp found mate in like 7 moves. I can't track down the reference he makes to this position in "The Chess Addict". I was assuming there was something better than advancing the pawn but who knows, with a caption like "White to move and mate in no moves" the board could very well be upside down.

I didn't see that either. I would start out by sticking the bishop on H8 threatening Q-G7 mate.

I didn't see past that. The answer didn't jump out and no time to ponder. I don't have a chess engine so if I don't see ti I ain't seeing it!

You still haven't posted solution to the one two or three puzzles back.."your favorite". That one starts off with QxH7 check, I think?

What I want to know is why they call them "quiet" when those are the ones that can blow up suddenly.

You were correct with the Qxh7+, after the king takes the pawn the knight takes the bishop and you can see it - it was the Queen sac I was talking about. The comp saw it in about 10 seconds. I've seen that before and it is one of the best puzzles no doubt. I started messing around with moving one of the Knights first but nothing doing even though that looked like a sure win to me for white it actually ended up as a loss. I'm definitely rusty :(

Heh. I guess he means closed positions with the idea of not letting the comp out develop you? Avoid complicated positions?

If you like chess puzzles there are 2 books I remember, Chess Openings, Traps and Zaps 1 and 2 by Bruce Pandolfini. Not puzzles but a good study of openings.

Your opponent obviously blew the opening in a big way. He was in deep trouble from the start. Another fine example of why I never respond to e4 with c5. You -really- need to be on your toes if you're going to do that.
