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 has a knight and a pawn for a rook. Black must take into account the simplifying maneuver Qe6+. This suggests 29... Re8, threatening 30... e2: A) 30.Qe2 Nxg3+ (slower looks 30... Qxg3 31.hxg3 Nxg3+ 32.Kh2 Nxe2 with the idea Nf4, e2, etc.) 31.hxg3 Qxg3 32.Qf1 e2 33.Qg2 ...

agb2002: Black has a bishop and a knight for the bishop pair and a pawn. White threatens 32.Rxe7. The position of the white king invites to play 31... Qxh4+: A) 32.gxh4 Nxd3+ A.1) 33.Kh1 Nxf2#. A.2) 33.Bf4 Bxf4+ 34.Kh1 Nxf2#. A.3) 33.f4 gxf3+ and mate in two. B) 32.Nh3 Nf3+ B.1) ...

agb2002: Black has a bishop and a pawn for a knight. Black can win decisive material with 21... Bxc3: A) 22.bxc3 Qxc3+ 23.Kb1 (23.Kd1 Qc2#) 23... Qxd1+ and mate in four at most. B) 22.Re2 Bxb2+ and mate in two. C) 22.Kd1 Bxe1 23.Kxe1 Qc1+ followed by 24... Qxb2 wins. D) 22.Rd1 Be1(b4,a5)+

agb2002: White has an extra knight and can deliver mate in two with 17.Nf6+ and 18.Qh7#.
 
   May-17-15 I K Sukandar vs Hoang Thi Bao Tram, 2014 (replies)
 
agb2002: The material is identical. There are a number of candidates: 16.Bxf6, 16.Bxh7+, 16.Nd7, 16.Ng4, 16.Rd7, 16.Rh4, etc. I don't know. I'd probably play 16.Nd7 to eliminate the best defender or get the bishop pair.
 
   May-16-15 B Warszawski vs Robert Graca, 2009 (replies)
 
agb2002: White is one pawn down. The first idea that comes to mind is 21.Rxh7+ Kxh7 (21... Kf8 22.Qf7#) 22.Qf7+ Kh6 (22... Bg7 or 22... Kh8 23.Bd3 and mate soon) 23.Bd3 A) 23... Bg5+ 24.Kb1 A.1) 24... Rg8 25.Rh1+ Bh4 26.Rxh4+ (or 26.Qxe7 Qe1+ (26... g5 27.Qh7#) 27.Rxe1 Bxe1 28.Qxe5 + - ...

agb2002: White has two pawn for a knight. Black threatens 28... Qxc8 (29.Rxf6+ Ke7 30.Rf7+ Kd8). This line suggests 28.Bd7: A) 28... Qxd7 29.Rxf6+ A.1) 29... gxf6 30.Qxd7 Be7 31.Qc8+ wins. A.2) 29... Ke7 30.Rf7+ and mate next. A.3) 29... Ke8 30.Qg6+ Ke7 (30... Kd8 31.Rxd6 wins) 31.Rf7+ ...

agb2002: Black has the bishop pair for a bishop, a knight and three pawns. White threatens 26.fxg8=Q+. Black can deliver mate in five with 25... Bxg2+ 26.Kxg2 Nxf4+ (or 26... Nh4+) 27.Kh1 Rg1+ 28.Rxg1 Qf3+ 29.Rg2 Qxg2#.

agb2002: White has a rook and a bishop for two knights and three pawns. The bishop is immune due to Qxg7#. White must take into account the maneuver ... Qe4+ Rg2 Ng3+ winning the queen. This suggests 29.Re1: A) 29... Nxe1 30.Rxe1 A.1) 30... Ne3 31.Qxg7#. A.2) 30... Qd4(c3,b2) 31.Re8+ Rxe8

  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!

Nov-25-12  ShahMaat: ...no comment.New guy on the block.I enjoy the dialogue between the users.I thank you all,and look forward to crossing swords with you!Unrated old fart.
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!

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".

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:

G Weissgerber vs A Van Nuess, 1933

With friendship, respect and gratitude for your time in looking at this,

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?

Jun-21-14  Patriot: <agb2002> Thanks! I haven't been logging onto the site much recently--it's been about a week since the last time. I seem to be pulling away from chess more and more these days but that's how things go sometimes. Take care.
