When to try for a cheapo?

When is it worth trying for a cheap shot?  I found myself asking this question in a recent Team 4545 game.  I had the opportunity to lay a superficially inviting trap that would win a queen for a bishop if my opponent fell for it, and would lose a tempo in a closed position if they didn’t fall for it.

I went for it, and moved 21. Bd3 as white:

My attempted cheap trick.

Before this move, the d4 pawn had two attackers and two defenders.  I’ve blocked my queen’s defense of the pawn, superficially hanging the pawn.  The hope is that black captures:

21. … Nxd4?? 22. Nxd4 Qxd4 23. Bxh7+! Kxh7 (or any other move) and 24. Qxd4 wins the queen.

It wasn’t strictly the best chess move I saw, assuming perfect play for my opposition.  But in this situation I couldn’t see any winning responses for black to use the tempo, other than to get a start on the lengthy process of unwinding the traffic jam on the black queenside, and thought the possible reward was worth the risk.  I was also influenced by my opponent making many moves very quickly, and thought he might not see the whole sequence.

I know that the ‘official’ guidance is to not attack or offer a trap that will leave you worse off if your opponent plays perfectly, but there’s the trick:  how much worse off is too much?  In the game black played Kh8, showing that they saw through my cunning plan but not giving me any big reason to regret the lost tempo.

Post Script:  Entertainingly enough, when going through the game afterwards with the computer, it turns out that 21. Bd3 was a great move.  Not for anything I saw, but because it set up a removal of the guard tactic by taking the knight on f5.  The e6 pawn is overworked defending both the f5 knight and the d5 pawn.  After 22. Bxf5 exf5  23. Nxd5 it looks like I’ve forked the black queen and rook, but black can weasel out with Rxc2 threatening my queen, and we either trade queens or not after that.  Another entry for my tactics training!

Chess Blog Carnival III has arrived

If you wander over to Blunder Prone’s neck of the woods, he has the third Chess Blog Carnival all set up and ready for the punters:  Chess Blog Carnival III:  Renaissance Faire Edition.  This is a great amalgamation of articles and posts from all across the chess blogging community, and has opened my eyes to a number of new sources of inspiration.

For back issues, check out Carnival I hosted by Blue Devil Knight, and Carnival II hosted by Brooklyn64.

There are plans in the works for an April edition, I’ll post links to the submission forms when I find them.

Lots of easy tactics

Empirical Rabbit is talking about starting on the Heisman-Bain path for tactics training, and has a great post explaining the direction he’s taking on it.

I’ve started on the same path, also inspired by Mr. Heisman. My internal debate though, is whether to go through the problems in the Bain book, or whether to use a custom problem set on chesstempo.com.

Bain PGN:
– guaranteed quality problems
– good balance of the different tactics
– strongly recommended as being the right level

Chesstempo.com
– success/failure and time taken automatically tracked
– available from multiple machines
– ability to easily create lists of problems that were missed or took a long time to get.
– easy to shuffle/order the problems as desired.

I’ve been using Fritz 12 to go through the Bain PGN that I’ve got, but the lack of success/time tracking is killing me.  I’ve also tried to use ChessPositionTrainer 3, but the laggy interface and the way that getting the problem on the second or third try is marked as success was too painful as well.

Any recommendations on better software for tactics training if you’ve got your own PGN files?  Extra points for iPod/iPhone apps that I can use on the train commute.

Team 4545 Round 3 Report: Victory!

Here’s the raw game, will attempt to embed the game with annotations soon. It appears that wordpress is helpfully eating script tags for me…
http://www.team4545league.org/pgnplayer/pgnplayer.php?id=43876

Tense game, but victory for the Desert Ducts on board 4 tonight! I saw that my opponent *always* plays the French, so spent some study time before the game.

Managed to block his play on the q-side, and with a bit of his cooperation managed to cramp his queen, knight and two rooks into a traffic jam in the corner. Which allowed me (perhaps for the first time?) to build up on the king side like the position told me to, and let “tactics grow on strategies”.

I’ll be going over my game for a while, I think this is the best quality game I’ve played yet. (Said before I see all the mistakes in the computer analysis…)

Tactics Training

This is a post I originally wrote on the chess.com forum about their Tactics Trainer software, but it’s relevant for tactics training in general.  One relevant piece of background is that Tactics Trainer is timed, with the time limit equal to double the average successful solving time for each position.  The time limit affects your rating, but doesn’t influence how much time you have available to solve the position.

I’ve got a question for the other members who are passionate about Tactics Trainer:  What’s your objective in using Tactics Trainer?  I’m not trying to be clever or sarcastic, it’s a real question that has strong implications about what functionality TT should have, and how to use it.  These are the reasons I can think of to use TT:

  1. Get better at chess, whether fast or slow
  2. Get a high score in Tactics Trainer
  3. Fun, boredom, etc
  4. You can’t get enough of hansel’s blank comments or Joe Blob’s blog posts.

For me, the real goal is to get better at playing chess in actual games..  And for this reason, I use TT in a specific way that from the forum comments seems to be fairly rare.

  • Set it to Rated mode (as opposed to unrated and untimed)
  • In the Settings, uncheck “Show Timer”, so the timer is hidden while I’m solving the position
  • Also in Settings, check “Always show white on the bottom”
  • In each tactic, don’t move a single piece until you’ve worked out the whole problem as far as TT will take the line, including any delaying or interposing moves your opponent can make. In short, only move the first piece when you would be confident enough to play it in a competitive game.  In practice, I also give up if I can’t see the tactic after 4 min or so.
  • When I get a tactic wrong, I check the right answer, and then play it through myself moving the pieces with “Try Again” a few times to get the new pattern embedded.  Perhaps most importantly I describe to myself what features of the position should have triggered this pattern.  Loose pieces, unsafe king, etc.  This helps me really imprint new patterns.

Why do it this way? In order to make sure I’m using these patterns in real games every time I need to recognize them quickly, and make sure the patterns actually work in the current position.  The patterns will suggest candidate moves in the current position, but in a real game I need to calculate the line through and make sure that the move is safe and successful all the way through before I move a piece.  This is the combination of skills that I want to practice with Tactics Trainer:  finding candidate moves and calculating them through to the end of any tactics, quickly and reliably enough to use in a real game.

Why not show the timer? I see a lot of complaints from people that Tactics Trainer “forces them to move quickly”.  I can see how you’d feel that way, and that’s why I turn off the timer.  It’s artificial anyway, and it’s good for me to learn to see from the position whether it’s a simple or complex tactic.

Won’t taking all that time drop your rating? Using the above approach, I’m aiming for a very high pass rate, even if I sometimes take too long on the tactic and end up with 20% and a negative rating adjustment.  That’s ok, it doesn’t mean I’m a bad person or worth less, but that I need more practice with this type of tactic to get it cold and recognize it right away, or to be able to calculate better/faster in these types of tactics.  The alternative is to impulsively make a move once you see a pattern, even if you don’t know if the move is safe.  Doing that gives you bad habits, and the ratings hit from a number of 0% failures is worse than the occasional 20%.  When I first started this approach I had a drop in my ratings for a week or two, but I quickly jumped 150-200 points above the plateau I’d been on for quite a while.  My Live game ratings have also jumped since I started this.

Why always have white on the bottom? Because tactics aren’t always about offense.  In fact, probably the most important use of tactical skill is when testing whether one of your candidate moves is safe:  if I move my piece here, does my opponent have any tactics against me?  Keeping white on the bottom means that any “black to move” tactics are giving you practice recognizing tactics from the other side.  For some tactics that’s not too hard, but I don’t mind telling you that I have a way harder time recognizing some patterns like the the Philidor Legacy mate from the other side!

I hope you’ve found this novel useful, and at least got you to think about what you’re really looking for from working on tactics.  I’m curious to hear from other people what your goals are for tactics, and how do you work on them?

First Move

Hello, and welcome to King and Pawn.  This blog is intended to shed some light on the path of chess improvement, for both of us.  I’ll be writing about what I plan to do for improvement and why, what I actually end up doing, and what went entertainingly wrong.  Hopefully through conversations on this and the other chess improvement blogs we can help each other make progress.

Quick background on me:  I’m a husband and father to a fantastic 18 month old son (pawn), which definitely has an impact on my playing/study time.  My day job is as a software product manager for business and data analysis, and I live in London.

I play online as cdir, mostly on the ICC these days (1050 blitz and 1420 standard) and also on chess.com.  I’ve just started in the Team 4545 League in the U1600 section, and will be writing about my experiences there.  It was good to go over the first game with my opponent, and hope that this will help make up for my inability to get to the local chess club on Thursday evenings.

See you on the path.
