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: An overworked puzzle. Black is one pawn down. White threatens 28.Nc3 followed by Qxb7. Black can try to open the e-file to incorporate the rook into the attack against the white king with 27... Nf3+: A) 28.exf3 Qxf1+ 29.Kxf1 Bh3+ 30.Kg1 Re1#. B) 28.Kg2 Qxf1+ 29.Kxf1 Bh3#. C) ...

agb2002: White has a rook for a bishop and two pawns. Black threatens 26... Be2#, 26... Qxa1 and 26... Qxf6+. White can deliver mate in five by diverting the rook: 26.Qg7+ Rxg7 27.Rd8+ Rg8 28.Rxg8+ Kxg8 29.Ra8+ Qb8 30.Rxb8#.

agb2002: White has a bishop and a knight for a rook. Black threatens 29... Qxe6. White can win a piece with 29.Qxe5+ dxe5 30.Nxc8. However, three white pieces can attack the remains of the black castle and deliver mate after sacrificing one of them: 29.Rxh7+ Kxh7 30.Qg6+ Kh8 31.Qh6#. Or ...

agb2002: The material is identical. Black threatens 25... Qxf6. The rook on g8 prevents Rd8+. Hence, 25.Qxg7+ Rxg7 26.Rd8+ Rg8 27.Rd(g)xg8#.
 
   Jul-27-14 F A Hoffmann vs A Petrov, 1844 (replies)
 
agb2002: Black has the bishop pair and two pawns for a bishop and a knight. White threatens 13.Nxd8, 13.Nxh8 and 13.Qxd5. The position of the white king invites to play 12... 0-0 to create a mating net: A) 13.Nxd8 Bf2+ 14.Kh3 (14.Kg4 Ne3+ 15.Kh3 Nxd1 (15... d5+ 16.e6) 16.Rxd1 Rxd8 - + [B+2P

agb2002: Black has a knight for a bishop. The knight sacrifice 24... Nd4+ seems the logical start of the attack against he white king: A) 25.exd4 Qg4+ (25... exd4+ 26.Kd1 Qg4+ 27.Rf3 Qg2 (or 27... Qe4) 28.d3 and the attack appears to vanish) A.1) 26.Ke3(d3) Qe4#. A.2) 26.Ke1 exd4+ 27.Re2 ...
 
   Jul-26-14 R Borngaesser vs H Seegers, 1984
 
agb2002: I didn't find the time to analyze this puzzle but had the impression that both 19.Nf6+ and 19.Bxh7+ win, the latter being relatively more difficult because of the counter chances along the a8-h1 diagonal.
 
   Jul-24-14 H Richards vs S Williams, 2003 (replies)
 
agb2002: White has a queen and the bishop pair for two rooks, a bishop, a knight and a pawn. Black threatens 23... gxf4. The rook on d8 prevents 23.Qd6#. This suggests 23.Bc8+ Kf6 (23... Rxc8 or 23... Rd7 24.Qd6#) 24.Qxd4+ A) 24... Ke7 25.Qxg7 (25.Qc5+ Ke8 (25... Kf6 26.Qxc6+ Rd6 27.Qxd6#) ...

agb2002: White has a knight for a pawn. Black threatens 20... fxg5 and 20... bxc3. The convergence of the dark square bishop and the king's rook on h8 suggest 20.Qxf6, creating a mate net: A) 20... Bxf6 21.Bxf6 and mate in two. B) 20... bxc3 21.Qxg7#. C) 20... Kf8 21.Qxg7+ followed by ...

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.

  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,
John

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!

  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!

  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>

  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:

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>

  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!

  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!

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

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:

G Weissgerber vs A Van Nuess, 1933

  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?

  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.)
