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: Black is one pawn ahead. The pawn on e5 is momentarily safe (24.Nxe5 Rxd2 25.Qxd2 Qxe5; 24.Qxe5 Qxe5 25.Nxe5 Rxd2). My first idea is 23... e4, to open the b8-h2 diagonal for the black queen: A) 24.Nxe4 Nxe4 25.Bxe4 Nxg3 26.hxg3 Qxg3+ 27.Kh1 (27.Qg2 Qxg2+ 28.Kxg2 Bxe4 - + [B+2P vs ...

agb2002: <morfishine: <agb2002> Nice work on <24.Qc3>; Even after 24...Nf6, White continues the attack with 25.Rh8+ For example: 25...Kxh8 26.Nxf7+ Kg8 27.Nh6+ Kg7 28.exf6+ Kf8 29.Qb4+ Rd6 30.Qxd6+ Ke8 31.Qe7#> Thanks a lot but I'm afraid that Black would play 27... Kh7 and

agb2002: White has a pawn for the bishop. Black threatens 24... Bxf2+ 25.Kxf2 Qf6+ 26.Qxf6+ Kxf6 27.Bd2 Rf8 28.Bc3+ Kg5+ 29.Kg3 Rhg7 with a momentarily unconfortable position. The bishop on d5 stops Qe6#. This suggests 24.Rxd5: A) 24... Qxd5 25.Qc7+ Kf6 (25... Be7 26.Qxe7#) 26.Qf4+ Qf5 ...

agb2002: The material is identical. White threatens 30.Bd1. The white queen protects the square f3. Hence, 30... Rxd2 31.Qxd2 (31.Qb3 Rxd2) 31... Qf3+ 32.Kg1 Bh3 33.Be4 Qxe4 34.f3 Bc5+ 35.Kh1 Qxc4 - + [2B+P vs R] .
   Apr-21-15 Z Almasi vs Korchnoi, 1996 (replies)
agb2002: White has the bishop pair and a pawn for two knights. Black threatens 33... Rcxe7. White can deliver mate in three with 33.Qg7+ Rxg7 34.fxg7+ Kg8 35.gxf8=Q#. Much slower is 33.Rxf7 Rxf7 34.Qg7+ Rxg7 35.fxg7+ Kg8 36.gxf8=Q+ Qxf8 37.Bxf8 Kxg8 38.Bxc4 dxc4 39.Rd1 + - [R] . Also much ...

agb2002: The material is identical. Black threatens 25... Bxe2 and 25... Bxf2+ 26.Rxf2 Nxe5. The first idea that comes to mind is 25.d6, trying to exploit the airy position of the black king and touching the rook on a8: A) 25... Bxe2 26.Bd5+ Kg7 (26... Kf8 27.Nd7#; 26... Kh8 27.Nxg6#) ...

  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>

Nov-14-12  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!

Jan-18-13  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>

Jan-19-13  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!

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


Nov-01-13  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!

  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".

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:

Mar-05-14  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?

Mar-06-14  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.)

Mar-08-14  LIFE Master AJ: S Williams vs The World, 2013

Weren't you a big-time member of the team?
