A good puzzle would be to reconstruct the game up to that point (without using a database). It arises from a fairly logical sequence in a well known opening.

I saw ...Qg3 but I was trying to find something better!

I tend to prefer two minors over a rook even with a couple of pawns thrown in, unless there are more positional factors than what I see in that position.

Hey All,

I've played blitz for about 5 years, but have no experience in long games. I'm playing in my first tourney tomorrow at a 30/90 G/30 control.

Any last second tips? I'm figuring out my opening tree, going over pawn endgames, and re-reading "Reassess Your Chess".

It's to late to get better, but my thinking is I don't want to be surprised as a symmetrical opener (e4/e5, d4/d5), and want to be more solid on pawn breakthroughs that happen less often in blitz at my level.

I'm 1200 on chess.com blitz (i went down from 1400, another issue), and my opponents will be USCF 900-2200.

Thanks!

It's whites turn, any thoughts how white could win from that position?

Black committing a series of egregious blunders.

One promising line is 1. Rxf4 Bd4+ 2. Bxd4 Rc4 3. Bxc4 g4, and White is winning.

The indecipherability of the pieces might be a point in your favor. Maybe Black might mistake a pawn for a bishop, or the entire game for Arabic writing.

Sit on your hands? You need to fight the urge to make a move as fast as you would in blitz, and sitting on your hands will make sure you think before moving (plus, keeps then warm!). Good luck!

Major Prodigy Watch Update:

I have greatly expanded my spreadsheet. I am now tracking 40 different players, including all 23 people who have achieved the GM title prior to their 15th birthday (per Wikipedia). Furthermore, I have added a new output. I can now, for any age between 10 and 19 (to the nearest month) tell you exactly where each player ranks within the dataset. For instance: at the age of 13.5, Magnus Carlsen's highest rating to that point was 2552 (actually reached at 13.33). This is the SECOND best rating ever achieved at or before the age of 13.5. I'm not sure if I'm tracking everyone I should be, there may be players (particularly in the 10-12 age range) who spiked ridiculously high, but didn't reach GM level, who I should add to round out the record holders.

There are currently a few holes in the data. I have six youngsters who I just added to the list that I don't have a birthday for. Additionally, all my data comes off the FIDE website, which only goes back to 2000, so several players born before 1990 are missing data from early in their lives. If anyone can point me in the direction of FIDE rating lists from the 1990s, that would be wonderful! Also, if anyone wants to Google-stalk a few pre-teens, and find me birthdays of Javokhir Sindarov, R Praggnanandhaa, Boris Bogatyrev, Nodirbek Abdusattorov, Alireza Firouzja, or Parviz Gasimov, I would appreciate it!

Before I unveil the data in all its glory, though, I want to see if I can stump you all.

For ALL ages between 10.0 and 19.0, the status of "highest rating ever achieved at or before that age" is held by one of only four players within my data set. NAME ALL FOUR!

Contenders, listed in alphabetical order, by first name, aka everyone in my dataset:

Interesting concept. Could be improved though.

OK I tried the lichess opening trainer and it wasn't really what I thought at first. Most of the positions are "find 5 developing moves that don't lose material".

What I had in mind was positions with one or very few right answers. More like a flashcard system, see the position and try to recall the prepared move. Does anything like this exist?

Mini-quiz time. These positions are from my blitz games with weakened engines. After zooming through a batch of super-GM games in Arena 3.5, it's often difficult for me to resist a short duel against the comp, so as days pass, the games accrue.

Find the best move. If one side is completely winning regardless of what he does, find the quickest win.

None of these should be too hard for anyone >1400, so time yourself. Check the solutions and collect your points afterwards.

1)



2)



3)



4)




5)




Spoiler:

1) 1.-Rab8 activates Black's pieces. After either 2. Rxb8 Rxb8 or 2. Rxa6 Ra8 3. Rb6 Rxa3+ (3. Rxa8), Black is closer to converting the exchange.

Full credit for 1.-Rab8 and the temporary pawn sac idea.

2) Black is completely winning, but 1.-a3! does the job the quickest: 2. axb3 a2, and if the b pawn is allowed to sit there it'll march forward.

Full credit for 1.-a3.

3) White has a sick lead in development, but there's no immediate win. The developing move 1. Be3! is not only principled but also tempts a blunder. 1.-Qxb2?? 2. Bd4 and Black will lose material. (2.-Qb5 3. Bxf6 exf6 4. Nd4+).

Collect a full point for that idea. If you missed that, you can collect a consolation half point for noticing the pawn sac 1. d6!? Qxd6 2. Qxd6 exd6, which is too fancy but still viable.

4) 1.-Bxe5 is obviously crushing so that isn't worth anything in itself.

Give yourself half point, up to a full point total, for each of the following lines (you need to notice at least two of the four to get full credit):
a) 2. dxe5 Rxe5+ 3. Bxe5 Qxe5+ and 4.-Qxa1(+)

b) 2. dxe5 Rxe5+ 3. Kf1 Rf8 and then either 4. Qxf8+ Qxf8+ 5. Rf2 Rf5 or c) 4. Bxe5 Rxf3+ 5. Ke2 Qxe5+ and 6.-Qxa1.

d) 2. Re2 Qd2+ or 2.-Rxd2+ 3. Qxd2 Qg3+.
5) A full point for 1.-Rd8! 2. f5 f6+ 3. Kf4 e5+, gaining space and beating White's king off back (oops).


Noticing moves that involve fake pawn sacs seems to be my forte. I calculated the line in #3 within 3 seconds of Black's move.

This is not a tactic (that I'm aware of). It's a position from a game I just finished.



White to move.

Is there anything in this position? I couldn't find a plan, we agreed to a draw. I couldn't run this through a computer because it was a 960 game. Sorry for the picture size - don't know how to make others.

Oh, this wasn't the position we agreed to a draw. I went 25. Rd3 and my opponent replied with Qc5 (this was the same position as 23rd move).

maybe play instead of 25.Rd3, play 25.d4 followed by Re5(fixing the weak e pawn in place) with the idea of infiltration on the F file with a rook or a queen

d4/Re5 and then one needs to create a second weakness...maybe by pushing some queenside pawns.

Q@d8 is sort of wasted here, as is the R@d7...this is one of those positions where it makes sense to think about where pieces would be placed ideally and then just put them there to see where things settle. For example, d4/Re5/../Qb4 and then a5-a4 at least requires White to do something.

White is significantly better. He has every important file -- d, e, and f -- a target on e6, and Black's queen is hilariously placed. He has all the winning chances, so agreeing to a draw was a big mistake.

Plans are overrated. You can just gradually improve your position (d2-d4 and other pawn advances). I'd start by looking for concrete lines (plan-first approaches are meh): 1. Rd3 Qc5 2. Re5 Qb6 3. Rde3 Kd7 (if 3.-c5, that pawn comes under fire after 4. R3e4 and 5. Qe3, with Rc4 and b4/d4 in some variations if Black moves the queen and plays b6) 4. d4 Qc7 (otherwise 5. c4 and 6. d5 probably picks up the pawn) 5. h4, with the idea of creating a second weakness with h4-h5, is the first idea that comes to mind*.


ETA: *This sentence was a lot simpler at first, but I noticed other Black resources and had to address them, and I'm still spotting annoyances here and there. Sholar's 1. d4 2. Re5 is a "gradual improvement" that should be sufficient.

Thanks. Playing d4 didn't really cross my mind. I strongly considered b4, but I didn't see a follow up idea. Also, for whatever reason, I thought having all of my heavy pieces on the same file was good (primarily because I couldn't figure where else, but also since I knew his Queen had to play defense).

Edit: @Rei I didn't mean plan* in any way other than "Soooo, where the hell should I put my pieces now?"

* I'm guessing plan has a very technical meaning the way you are using it.

I like 25.Re5, intending R2e3 and Rd3, or R2e4 and Rd4. Basically just move your rooks up the e-file, to tie him down completely, and see what he does. He has to do something weakening, because the threat of moving the back rook to the d-file instead of the front rook leaves his queen trapped.

He might have to choose between something very passive like ...Qd7 and ...Qc8, or weakening with ...c5. In the latter case you can attack with some combination of Qf2, b4, R2e4, and/or d4.
