Emulating Role Models And How I’m Applying It To Chess

When I was a young basketball player I tried to copy the style of Kareem Abdul Jabbar. After a while I developed a very passable version of his Sky Hook.

When it became clear I wasn’t going to grow to be over seven feet tall I changed the guy I was copying to Vinnie “The Microwave” Johnson. Vinnie is best remembered as the first guard off the bench for the Bad Boy Pistons of the early 1990’s. He was exciting and he could score in bunches from all over the place, hence the nickname “The Microwave”. He wasn’t much of a three-point shooter but he didn’t let that stop him. And that’s how I made the transition from “big” to “guard”, by copying a guy who was stylistically nothing like Kareem. A whole lot more of my practice time went into shooting jump shots and ball handling rather than Sky Hooks.

I think there are many times in life when learning how to do something that it’s helpful to find someone who’s good at that thing and try to emulate how they do it. It could be any activity from basketball to baking bread. When searching for a model to emulate I need to see their style as attractive and/or efficient, and it should be a style I think I can potentially copy reasonably closely, even if my version is pitched at a lower level.

When playing chess I’ve decided that I play best as a quieter positional player, rather than a player who’s more focused on fireworks and tactics. As a teenager – emphasizing tactics, deep calculation, and using memorization-dependent openings was a realistic way to play. As an adult With Things To Do I’m much happier squeezing opponents positionally until they crack.

In light of that, I used SCID vs PC to make a White database and a Black database for the players I’ve decided I want to try to emulate. I don’t think it’s a perfect list, but it does allow me to go to the Tree Window in SCID, look up a specific position, and see how it was played by my group of model grandmasters. The model grandmaster list is below, with a little (partially AI generated, then edited by me) blurb that describes a bit about how each one plays:

I’m sure I’ll add/remove guys from the list over time. But for now it’s enough total players, both old and new, that it should cover most situations I’m likely to run across over the board. It’s also enough of a sample size for Wisdom Of The Crowds to kick in. My nickname for the group is “The Posse”. As in: “Let’s see what The Posse has to say about this position”. I think the name is fun and irreverent, so there it is:

Adamsdeeply strategic, focusing on building small, incremental advantages without taking unnecessary risks
Anderssonextreme positional solidity, elite prophylaxis, and a “slow squeeze” technique
Botvinnikgrip his opponent in a vice straight from the opening,  then squeeze him methodically
Capablancasupreme simplicity, incredible speed, and profound positional understanding
Dorfmanhighly structured, positional, and “algorithmic” approach to chess
Dreevactive positional style
Fischeruncompromising, aggressive, and highly principled approach
Gelfandpositional and classical player known for deep strategic understanding, precise maneuvering, endgame
Girisolid, positional, and deeply theoretical style of play
Karjakansupremely solid, defensive, and positional player “Minister of Defense”
Karpovimproved his position by positional understanding. Few risks, few mistakes “Boa Constrictor”
Leko“cemento” (cement), “clean and clear” style focused on extreme solidity, positional mastery, endgame
NimzovichHis approach was strategic, patient, and often aimed at forcing zugzwang
Petrosianextreme caution, deep strategic planning, and an almost impenetrable defense
Reshevskygrinding. “calculating machine” who thrived in complex, closed positions
Rubinsteinpositional, logical, and technical style, often focusing on accumulating small advantages, endgame
Seirawanpositional, strategic, and classical. compared to a “19th-century player” for his complex, slow-burning games
Smyslovharmonious, profoundly positional style, often described as a modern-day Capablanca
Tiviakov“rock-solid” positional style, deeply rooted in the classical Russian school.

They all play differently. You could (correctly) say that some play very differently from others. But if I can play like a poor-man’s amalgamation of that group with any consistency I’ll be pretty happy with it. To date I’d mostly been “following” Adams, Karpov, and Tiviakov as models. I recently added Capablanca. Those four guys will be the tie-breakers when there’s a difference of opinions in the databases.

None of this is anything I could have conceived of as a teenager. It’s pretty neat that these tools exist now.

In conclusion, a picture of Vinnie because Vinnie deserves some love too. Here he is beating Danny Ainge off the dibble:

Scid vs PC. Thoughts About The Getting Started Process

I think I now have the very basics of Scid vs PC together. Initially I was somewhat hesitant to get involved with the setup because I wasn’t really sure where to go or what to download. And because I wanted to focus on other things chess. Then there was the word “database”, which can often translate to “Byzantine”, which was also a turnoff. To try to warm up to the idea I watched parts of a few (mostly dry) videos and chose to dive in.

Here’s how I got started:

I downloaded Scid vs PC here.

I ultimately decided to start with just the OTB (Over The Board) files at Lumbra’s Gigabase. It’s actually about ten zipped files containing 9 million+ games of OTB, split up by years or decades (or more). The free unzip utility I used was 7-Zip (here).

The “trick” is to download all of the zip files, create a new database on Scid vs PC, then load each unzipped file into that database so all the games are in one larger db file. Then save *that* file to a new name. That’s the file to be used going forward.

There are millions of online games available at Lumbra’s as well. My feeling is that I may download them at some point, but for now I’m mainly interested in parsing the database for masters OTB games. For example: as White when I play e4 and Black responds with the French defense – I like to play the Tarrasch variation. For model games I can search the main database for just that ECO code, and further narrow my search for GMs I’d like to try to emulate in that opening, for example, Michael Adams. Even better, search terms can also include things like “White Wins”, or “Only games with between X and Y total moves.” I used that last feature to remove super long games since what what I’m really interested in are the openings and middlegames — I can study endgames separately. All of these options are available in the General Filter.

In Scid vs PC there is always a “scratch pad” database open called “Clipbase”. If I search and get say 15 games from one GM and 20 from another, it’s literally a drag and drop process to combine all of those games into the Clipbase, which can then be saved as a new database or exported as PGN game files (or a bunch of other options I haven’t really played with yet.) Note that Clipbase doesn’t and won’t save, so make sure to save what’s in Clipbase as something else if you care about the contents before you close the program.

One neat thing about the PGN export option is that by combining the model games into groups of a maximum of 64 PGNs they can then be easily imported into (also totally free! yay!) Lichess Studies, and Lichess Studies automatically divide the PGN files out into one game per Chapter. So I can have a Study of model games of one particular opening I’m interested in, (or one GMs selected games), and I can share those Studies with friends. (If you want the Study to stay “yours” then Select Unlisted (no one else can see) when creating it and invite your friends as Members. It’s also possible to set “Allow Cloning” and “Share and Export” to “Only Me” if you’re concerned with a Study getting broadcast. There’s no way to “un-ring the bell” if a Study gets public.)

A Note regarding importing bulk PGNs into a Lichess Study: I like to work through model games with the color I intend to be playing at the bottom of the screen — Lichess Studies give you that option to have Black or White at the bottom at the time that you import. If you forget to toggle Black or White at the bottom during a bulk game import then the only way to flip the games is one at a time. Which means you’re better served just trashing the Study and getting the import orientation right the second time.

With Scid vs PC it’s possible to download different analysis engines. It’s also possible to download your own games from your chess website of choice. I haven’t done it yet but you can search the database for specific positions, or specific pawn structures, or search by the material that each side has remaining.

That’s not close to everything you can do with Scid vs PC, I’d recommend checking it out. I think it’s a really nice tool that when combined with the Lichess Studies makes viewing selected games on the go very convenient. I’ve also used the Scid vs PC and Lichess Study combo to put games that are in a paperback “Opening” book into a Lichess study, so I can follow along on my phone or laptop rather than getting a board out and moving pieces around.

Again, highly recommended and not nearly as scary as it all sounds.
