I'm an applied mathematician who lives in the south east of Spain.

My approach to the puzzles is similar to that of David Zechiel (User: dzechiel): I first write the variations I find in a reasonable amount of time (using the puzzle diagram only) and post them before watching the game or other's comments. Then I have a look at them and try to be critical with my work. I apply the touch-move rule to my posts (see Unzicker vs Fischer, 1960). I hope to improve my tactical vision this way.

Often I cannot even spend a couple of minutes looking at the diagram (work, family, other interests, etc.) so I try to blind solve it along several breaks. My first attempt was R Vera vs S Garcia Martinez, 2001 and although the variations I found were not very deep I felt quite satisfied with the experience.

agb2002: I don't know whether the adjective would be Caruanian or Carvanian if he achieves 10-0 but what I know is that it would be much closer to Caru-one.
   Sep-02-14 Adams vs M Maki Uuro, 2004 (replies)
agb2002: White has a bishop and a knight for the bishop pair. The weakened black castle invites to play 17.Bxh7+, paving the way for the heavy pieces: A) 17... Kxh7 18.Qh5+ Kg7 19.Qg4+ A.1) 19... Kh6 20.Rd3 Bxf2+ 21.Rxf2 Qc5 22.Rh3+ Qh5 23.Rxh5#. A.2) 19... Kh7 20.Rd3 Be3 21.Rxe3 Qxe3 ...

agb2002: The material is identical. White can deliver mate in three with 28.Qd8+ Nxd8 29.Rxd8+ Rg8 30.Rxg8#.

agb2002: Can't believe I missed 31... Bxg2+. Better luck next Sunday.
   Aug-30-14 M Dziuba vs A Ipatov, 2009 (replies)
agb2002: White has a bishop for a rook. Black threatens 30... Rxg8. The black king cannot move and White controls the dark squares around the black castle. This invites to play 30.Qg3, threatening mate in one and to resume the attack through those squares: A) 30... Rxg8 31.Qg5+ Kh7 32.Qe7+
   Aug-29-14 J Seoane vs I Prieto, 1986 (replies)
agb2002: White is one rook down. Black doesn't have useful checks after 15.Kd2: A) 15... Qxa1 16.Qe8+ (or 16.Nxc6+ as in B) 16... Kxe8 (16... Rxe8 17.Nf7#) 17.Nf6+ Kf8 (17... Kd8 18.Nf7#) 18.Bh6#. B) 15... Qxh2 (or 15... Qg2) 16.Nxc6+ dxc6 (16... bxc6 17.Bxe7+ Nxe7 18.Qxe7#) 17.Bxe7+ Kd7 ...
   Aug-28-14 Rublevsky vs J Becerra-Rivero, 1997 (replies)
agb2002: The material is identical. White's heavy pieces and a pawn aim at the black king. This suggests 31.Rxh6: A) 31... Kxh6 32.Rh2+ A.1) 32... Kg5 33.Qh5+ Kf4 34.Rh4#. A.2) 32... Kxg6 33.Qg4+ Kf7 34.Rh7+ Ke8 (34... Kf8 35.Qg7+ Ke8 36.Qe7#) 35.Qg8+ Rf8 36.Qxe6+ Kd8 37.Q(R)d7#. A.3) ...
   Aug-27-14 Shirov vs S Kristjansson, 2004 (replies)
agb2002: The only reason I can imagine for not seeing 35.Rc4+ is that this move was discarded because one move earlier Black could deliver mate in two.
   Aug-26-14 Botvinnik vs N Sorokin, 1933 (replies)
agb2002: The material is identical. The bishop on a5 is defenseless but after 12.Qb5+ Nc6 protects it. Hence, 12.Bxb8 wins a piece: A) 12... Rxb8 13.Qb5+ and 14.Qxa5 + -. B) 12... Bd7 13.Bg3 + -. C) 12... Qc6 13.Bb5 + -. D) 12... Bxc3+ 13.Qxc3 Rxb8 14.Qxc5 + -.

Jan-01-12  CHESSTTCAMPS: <Yes, we experience similar price increases here. ...>

I take note of your point about Morroccan fruit being held to lower standards. Giant Foods has carried both Spanish and Morroccan clementines in recent years, the latter usually starting in January and later. Usually, both are delicious. I think that Giant is a reputable outfit and they would take care that their label means what it says. In any case, if there are serious doubts about the source, I think that consumer watchdogs would raise the issue loudly and clearly.

<Similarly, avoid some Italian "products",....>

This is interesting, something I was not aware of. I am a regular consumer of olive oil.

<Thank you, I wish you the same for you and your family and a good New Year.>

Thanks, Happy New Year to you, too.

  Patriot: <agb2002> <Hello Patriot, how is the new year treating you? Hope everything is ok with you and your family.> My apologies for not responding to you sooner! I really thought I had responded back and just noticed I haven't!

Everything is going well with me and my family. I appreciate you asking and I hope all is well with you! Keep up the amazing work on the puzzles! Take care.

  johnlspouge: Hola, <Antonio>.

Thanks for "dropping by". I hope you and your family are well.

I looked at the reviews of Penrose's "The Road to Reality", which I have not read, and I am daunted. Do I want to spend the time and effort required to understand the book?

I therefore turn your question back to you: what did you think of the book?

Be judicious in your answer, please ;>)

All the best,

Premium Chessgames Member
  johnlspouge: Hi, Antonio.

Your review link was good enough. The book is a must-read. I will let you know how it goes.

Thanks for thinking of me :)

All the best,

Thank you! It seems that the interest on Penrose's Road is skyrocketing: I can count three now which means a tremendous increase of 50%! ;-)

Jun-11-12  LoveThatJoker: <agb2002> Hi! I'm sending you this note to firstly thank you for your kind and objective acknowledgment on M Beinoras vs H Salo, 2009. I made sure to post my original thank you there!

I had a fellow CG full member, <AlienMath> post a question on High-Mathematics on my forum that I cannot assist on elucidating on, due to the fact that I am not a trained Mathematician.

The question is located directly on this link LoveThatJoker chessforum.

Any help on the elucidation of the concepts of both the Goldberg conjecture and the Riemann hypothesis would be genuinely appreciated.

Thank you!


Jun-12-12  LoveThatJoker: <agb2002> Thank you for the kind reply on my forum!


Jun-14-12  LoveThatJoker: <agb2002> Do you have any idea who this is?

Look at Book 3 here

I will give you anyone you want in exchange for this one.


Jun-15-12  LoveThatJoker: <agb2002> Thank you for getting back to me on that!


Premium Chessgames Member
  Patriot: Hi <agb2002>! <I agree. I still have to rethink my move selection algorithm.> Usually you latch right on to the correct move. Do you consider other candidates or do you usually only post the principle candidate after analysis? For example in today's puzzle, I thought 22.Bh6 was a good candidate and 22.Nb5 was interesting, although I didn't post anything about it initially. 22.Rxf6 was the first move I saw but I didn't see the Kh1, Rg1 idea and thought it was unnecessarily complicated.

By the way, good job on the POTD!

Premium Chessgames Member
  morfishine: Hello <abg2002>! Nice write-up in the Sunday POTD! I only noticed <25...Bxe4> immediately after posting 25.Rxb4 <25...axb4>. I briefly considered deleting my post then adding this as a possible improvement but decided to leave these separate.

I'm a bit surprised there wasn't more discussion on <25...Bxe4>

Premium Chessgames Member
  Patriot: Hi <agb2002>! Good job on your win! I read your comment about losing the exchange before going over your game so when you played 20.Rae1 I figured the rook on f1 was going to be *the* piece. I've lost the exchange quite a few times like this so I'm very suspicious about moves that trap the rook.

I had a question about 11.Nxe7+. What prompted you to play this? That knight is a real thorn thanks to 9...b6?. I wouldn't recommend trading it until forced to do so since the bishop isn't going anywhere. That's similar to what Dan told me once when I captured a pinned piece. He said "You should almost never capture unless they threaten to break the pin or capture the pinning piece, for example." By not capturing, you have time to build your position further while he is left dealing with the situation.

It really looks like you did have a bad day though--we all have them! I just thought I'd mention the knight capture though because that move really stood out with me. But it's probably something you wouldn't have done on any other day!

Thanks for sharing!

  Patriot: Hi <agb2002>! I loaded your game into Fritz and followed it. You played a nice game against Houdini! On move 35 (white to play), how did you evaluate the position:

click for larger view

I might think black is a little better, and Houdini agrees after 22-ply. You said 35.Bf1 was better but at 22-ply, it agrees with you! <35.Ba6>

Premium Chessgames Member
  Patriot: Hi <agb2002>! <Perhaps the note below the players showing the engine which performed the analysis misled you.> Yes this is exactly what happened--I completely misread that (sorry).

Your plan, having the outside passed pawn, is a good one. Nice game!

Premium Chessgames Member
  Jimfromprovidence: Thanks for the constructive feedback concerning Saturday's puzzle.


Premium Chessgames Member
  Patriot: <<agb2002>: <Patriot: <agb2002> <Pattern recognition finds the mate scheme...Therefore...> If the pattern led you to the sequence, I'm impressed. I had to work out a sequence before visualizing the position as a win.> You surely have already noticed that in competition chess you never have enough 'stored' patterns.> Oh definitely! I don't doubt that you solved it this way, but it struck me oddly because I have listened to NM Dan Heisman analyze <CG> problems that I gave him, "live". And I'm quite certain he would not have worked backwards from the pattern you illustrated. And I don't think, even knowing the pattern, I would ever be able to link the pattern to the problem and solve it backwards. That's one heck of a skill!
Premium Chessgames Member
  agb2002: <Patriot>

Thank you! The way you describe the solving process reminds me of Raymond Smullyan logic puzzles in his "The Chess Mysteries of Sherlock Holmes".

Dec-04-13  LoveThatJoker: <Dear CG Friends>

I know this is irregular, but I am stepping outside of the box, for you to view truly one of the most exciting alternate solutions ever posted on the daily puzzle:

  LIFE Master AJ: Hello:

Game Collection: "Chess-Games" >Problem of The Day< (2014)

I am trying to update a collection ... with all the puzzle for this year.

Have you missed any days this year ... that you know of? If so, could you help me to locate the missing days?

Premium Chessgames Member
  LIFE Master AJ: << Hello LMAJ, according to CG I have posted (or perpetrated) an analysis every day this year with the sole exception of Feb 17th (I don't remember what happened that day). If I can help you just let me know. >>

Cool! Then I will be looking through your posts and trying to update my collection. (I am glad that you don't mind.)

Think you could ask any of your friends and find out what the POTD for Feb. 17th was? (Ask them to leave a comment in my forum.)
