4th annual FBG chess tourney- Congrats to Kasparov! 1st place (1 Viewer)

thought this might be an interesting game

I completely blundered my usual solid london system opening here and came back to win in crazy fashion with some crazy tactics.

(also time pressure on both sides sped up the mistakes)

tommyboy and spOOfy, I need you to tell me what's going on in your game before the end of the day. If you don't post anything here, I have to remove you guys from the tourney and start round 3 tommorow. If your game is ongoing, all you have to do is let me know and we will wait.
game was/is still ongoing. guess that's fine if you wanted to drop us, but it was the holidays ffs. we were still playing slowly during that time but i wasn't checking in here to see. we said we started the game.

 
well, that kinda sucks we're bumped. you do remember that you got us started later because you originally had me matched up against otis, right?

 
did you think maybe to pm us?
lol

tim doesnt do PMs as I've learned all too well.
i don't check in here all that much, particularly when i'm on vacation with my family over the holidays. but tommy and i have had a good game and our play slowed down over that break time. some games were already finished before we even had a chance to start (because of the reseeding). oh wellz i guess.

I didn't PM. For that I apologize. But I made it very clear from the beginning that people needed to post here that their games were in progress and what was going on. After every game was finished except for yours, I asked for an update for two days and didn't get any. I note that your game is STILL ongoing and we're 2 rounds later. That's too slow, just won't work for this tournament. I do my best to give everybody an opportunity to finish.

 
andyjayhawker really outplaying me. I may be on the ropes here... he's playing a terrific game and I've made some mistakes.

 
I got lucky and fought my way back from 2 pawns down to andyjayhawker and ended up with a draw. Very difficult rook pawn endgame. I sent it to John Bender.

 
GG Uni and thanks for the game.

Lichess is down right now, will post results from tim/andy game and our game as soon as it's back up

 
Unialias vs Bender (0-1)

Some notes for Uni:

Move 4: Bb5+

"Generally" in these types of openings (E4 for white, C6, D5 for black) my "bad" bishop is going to be the light squared bishop. You're allowing me to trade it off here for free. Your "good" bishop is your light squared bishop. This is already an advantage for black. I might consider playing D4 here were I you, and placing my light square bishop on D3. Additionally, you're helping me develop my knight with this exchange to a square that it would want to be anyway. Essentially, you're doing black a few favors here in the opening with trading an undesirable piece. Note: in the Caro-Kann exchange that we played, the white bishop isn't as bad as normal since it's not blocked from development, but it's one I always look to exchange anyway.

Move 11. Ne5

Doesn't do much. I can trade it off and make your pawn look silly sitting there on the 5th rank with no support. I would probably develop your pieces here instead (the Knight you moved is already developed. From here I've basically invaded your territory and it's all downhill now. My queen is a tremendous pain in the ### and going to stop you from developing any further as it harasses your King. From there on out, it was just a matter of technique for me and being careful not to blunder or get my queen trapped.

Andyjayhawker vs Tim (1/2-1/2)

Too long to analyze too much, but andy probably needs to get his king more active in that end game. It didn't get beyond the 2nd rank until move 58. I know it's tough given the attacking threats you had but in rook/pawn end games, the king is usually going to be the key piece. With a king up on the 4th/5th rank you probably hold the win here. Tim's technique in the end game again brought it down to an 11 average centipawn loss which is, again, on par with a titled player with that many moves. So not too much to be upset about here when the opponent is playing that precisely. Both of you played well though.

I'll try to load this into chess base later and find any GM games with a similar opening.

 
Getz vs Juxtatrot (0-1)

Getz...

2. c3 - this is a useless move (I don't mean that tersely) - opens up your King side immediately, this pawn should be supported with another pawn or a knight. Leave those 3 pawns around your King in place unless you're playing a Dutch (which I know you were not). There's no need to move them this early in the game. It also forces your knight to h3 which is not a good square. When he plays the normal, H6, your Knight has almost nowhere to move to. So I think the downfall here was move 2 for you. From there you're just lagging in development immediately and it's hard to catch up.

5. d3 - now you've trapped your bishop inside the pawn chain where it can never be effective.

Much like my game with Unialias, this is just allowing his Queen to get extremely active and terrorize your chances at development, stalk your king, etc.

Wow! Fantastic game by both. I think tim's centipawn loss was the lowest of the entire tourney so far. Very impressive match.

 
Centipawn (1/100 of a pawn) measures the advantage of each player. A perfect move will result in a loss of zero centipawns, but lesser moves, even if they are not inaccuracies/mistakes/blunders, will cause the player to lose position and advantage, and centipawn loss measures that.

 
From my experience, most GM, IM matches for slow chess will be around 7 or less centipawn loss. It's the best indicator IMO to evaluate strength of play.

The longer the game, the tougher it is to keep it low. I've had slow games last 19 moves and only had a loss of 8 or 9 but I don't think I've ever been under 20 for a game lasting at least 30 moves. It's VERY tough to do. It takes pristine calculation the entire match through which is just not feasible for me.

A solid player who knows as much as a non titled player can about chess, can typically get away in a 30+ move game with 15-20.

Anything lower than that is pretty superior playing. Even if a mistake is made, it's usually calculated out as a positive by most computers depending on the ensuing moves. Even in the IM match I posted, we had 27 and 42 respectively.

By comparison, Kaspy (probably our best player) had 24 in his game vs Joffer. 11 for a 67 move game is amazing playing :tebow: but from playing tim on ICC the past few years, I know he's usually one of the more solid players I've come across.

what is centipawn loss?
"The centipawn is the unit of measure used in chess as measure of the advantage. A centipawn is equal to 1/100 of a pawn. Therefore 100 centipawns = 1 pawn. These values play no formal role in the game but are useful to players, and essentials in computer chess, in order to evaluate positions. -- http://chess.wikia.com/wiki/Centipawn

A perfect move will lose zero centipawn, but lesser moves will result in a deterioration of the position, measured in centipawn.

This value can be used as an indicator of the quality of play. The less centipawns one loses per move, the stronger the play.

These numbers are provided by the computer analysis, which is powered by Stockfish."

Great work John! Lots of fun to read. I had no idea what centipaen loss is either. What's funny is that I certainly wasn't confident that my moves were "correct" when I was making them late in that game. It was more like, let's hang on, see if he makes a mistake, maybe I can turn this into a draw if I get lucky.

Interesting. Looks like I miscalculated the end game and gave the game away at move 57. Tim played well and certainly capitalized on the mistake. I'm assuming my centipawn loss spiked a ton on that one move.

Yes, that is what it looks like to me as well. If you're viewing on a computer, there is a cool graph that shows it. Great tool, I've never heard of centipawn loss & like to follow my game & see an analysis of the errors.

 
RdRunner resigned. Not sure what happened, I was up two pawns but not in any kind of dominant position or anything.

 
For those that get a lichess account, you can use their training too: http://en.lichess.org/training/21815

we can also have a FBG Team on there to track each other easily and maybe play some quick games.

It's free, it's easy to use and it's the best chess "app" on the market (although their actual app for smartphones sucks - but if you're at a PC it's great)

IF you wanna sign up, please let me know your name.

I have played 400 bullet games in the last 2 days (home sick). I think my opening knowledge is as good as it can be for an old man - my middle and endgame needs a lot of work, so I play 0 + 3 speed. You start with zero seconds and bank 3 second every move you make. It's nice to bank some time in the beginning and rattle off 10 moves. I, admittedly, win many games due to time pressure above anything else. I need some work on quick mating nets and common bullet tactics.

Anyway - highly recommend lichess registration for everyone.

OK, but I still don't see how white wins after 57. kb3 kd6 58. kb4 kc6. Then what? What is white supposed to do? He can't take the pawn without trading it. He has to trade it for the a pawn, because if he trades it for the c pawn black forces a draw by hanging out in a8/b8. But if white trades it for the a pawn, then how is he any better off than he was with a4?

Started yesterday. It's going slow. I'll uodTe again later today. Hopefully we will pick it up

 
Kutta defeats Joffer in a well-played game where I got a bit lucky. Really could have gone either way.

gg. really thought we were headed for a draw. you had the bishop pair which offset my passed pawn. just couldn't get my pieces active. then that move this morning was just dumb.

It is admittedly a very tricky endgame for white, the win is there but correct play is required or this slips to a draw quite easily. The idea for white is to force black to defend the pawn, gain the opposition and win it by force.

So after 57. Kb3 Kd6 58. Kb4 Kc6 (forcing the defense of the pawn) 59. Ka5 Kc5 (gaining the opposition) 60. c3 Kc6 61. Ka6 (maintaining the opposition) Kc5 62. Kb7! the key move (and one that would be tough to find OTB) taking away the c5 square and forcing the black K away from its pawn Kd5 (62. ...Kc4 leads to 63. Kb6 Kxc3 64. Kxb5 Kb3 65. a4 winning) 63. Kb6 Kd6 64. Kxb5 Kc7 and either 65. c4 or a4 will win for white.
