What have I forgotten? Part 1: On tactics


Its been a while since I’ve really been able to devote serious attention to chess. I can say at least 9 months have passed, though I had a couple of cameo appearances back during the holidays. Back then, I was looking to see what I could retain from training and what I had lost from memory with a focus on “rust proofing” my training.  I had some marginal success and managed to not drop terribly too much in rating and performance.  So now that it’s been even longer since my last serious look at my studies, I thought I’d spend the month of May re-immersing myself back into the practice of chess improvement.

I am not so concerned about chasing the ratings than I am about learning a key concept about learned skill versus memorization. I really think that the positional studies I did with pawn formations last year really helped me develop a skill of positional understanding. I also realize I can’t escape the memory issues as certain variations and sharper lines do require this aptitude.

What are things that can be regarded as skills?
  •           Tactics
  •           Knowing Key positional concepts ( ex: IQP, Minority attacks)
  •           Endgame techniques
  •           Transitions
  •           Time
  •           Handling imbalances
  •           Defending
  •           Attacking
  •           Playing out of your comfort zone
  •           Knowing “your game”

I am sure there are more and I deliberately left out openings as I feel that this idea falls into the category of some memorization required.  Like coming back to a musical instrument, you may remember the scales or your old favorite song from motor memory, but that difficult piece you once played after practicing it  for hours before a single performance, doesn’t come back as easily. You only recall fragments.

So as I come back into this game, the first I look at are my tactical skills. About six years ago, I started on the MDLM journey of improvement my tactics through the seven circles of hell. I’ve completed two sets of 7 times 1200 problems  and had been on my third pass through when I realized that there was diminishing returns.  Before 2006, my tactical skills were abysmal. At the very least, the MDLM approach BURNED into my memory key patterns and underlying themes behind the tactics. 

So why do I still struggle with tactics despite being a rapid improvement “graduate” twice over?  It has to do with how I went about it.  After a certain threshold, my ability to recall and recognize patterns  were not mapped correctly. I wasn’t consciously creating my own narrative during each puzzle and most importantly during the ones I missed, not taking the time to understand why I missed it. Instead, because of the repetitious nature of the MDLM method, it was masked over with subsequent success and a false sense of security. In order for me to utilize the pattern recognition powers of my prefrontal cortex, I need to employ the correct supervised learning technique that only comes from the internal dialog when you are FIRST struggling with the problem. This process creates the right labeling that I can then use to recall the correct technique. Otherwise it falls under unsupervised learning and I take the “canned” labeling providing by the tool which doesn’t really mean anything and tend to cluster similar ideas together increasing my failure rate during recall.

In other words, even though the lower level of tactics  may seem easy to some, simply rushing through them to get to the next level without classifying each instance on your own terms  leaves you with clusters of patterns that may seem alike but require a nuance to perform correctly.

So as I started back up on tactical training to take the rust off, I was well aware that I had some patterns well mapped because I recalled the inner dialog I associated with the pattern.  For instance “ This is a geographical motif with a knight, but I need to remove the guard first and then white wins a piece.” If I don’t have this down for ALL THE BASIC THEMES, solving the higher levels becomes that much more difficult as those problems compound on top of each other.

Well it’s back to basics for me but with a new twist, “Supervised Learning”.   My blogging friend Temposchlucker at http://temposchlucker.blogspot.com/ has several posts about breaking down tactics and his own supervised learning approach.

My next post I’ll look at the supervised learning techniques I  used for positional understanding and how it’s been impacted with my absence from play.

It is very important to take the time to understand why a tactical trick works, and how you might have found it more easily. However, detailed understanding has to be repeated to be retained. Weteschnik’s book is helpful here. There is more to positional chess than key concepts! Whole books have been written on IQP. In practical terms, you could do a lot worse than to revise all the stuff that you have found helpful.

The black on white is much more readable than your previous white on black, but the hidden scroll bar is a pain!

I like this "supervised learning" sentiment, making sure one knows why something works.

The tactics stuff was alway true. Actually, I'd say that with the short time-controls these days that the MDLM teaching (in general) is the surest way to the rating-points bank.

For me, tactics study makes the most sense because endgame calculation appears to be a strength for me, and my play has been particularly goofy/poor when both sides retain queens on the board.

Lately, I've been "collecting" these examples of pawn sacs. GM Robert Hess in Chess Life just knocked me out with another great example and I had to pause my chess studies right there, he is a great games editor/analyst. Often, the purpose of a sac seems to be to get to the position where the tactics start. Without an initial sac, many a tactic never gets off the ground.

When it comes to study, my head expands most from those "My brain is full" type of problems, and tactics problems get me to that point the quickest. If that weren't the case, then I'd be switching back over to endgames. ;-)

Glad to see that there are people who actually understand what I'm writing. When I read the comments on my blog I often doubt if I'm writing clear enough.

You where talking about strategic puzzles, do you use a special book or software?
