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.

Look at Book 3 here http://chessbase.com/newsdetail.asp....

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

  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:

  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.)
