Rodent Karpov, the winner of the first Tactical vs Positional Challenge showed his class by defeating the 3300 level chess engine Komodo 10.4!

That’s right. Rodent Karpov, a version of Rodent that was deliberately weakened in order to mimic the highly positional style of Anatoly Karpov did the seemingly impossible.

Wanna learn how a 2800 engine personality crushed a 3300 powerhouse?

I’ll start from the beginning…

Last week I was investigating the following line of the French…

French Defense, Winawer Variation, 6…Qa5-a4 line

Here’s the line in question…

This line for black is definitely playable, and if black is careful on the kingside and doesn’t let white’s bishop pair get out of hand, he has a real chance to emerge with an advantage (or at least equality).

So as I do when I’m investigating a line, I ran a tournament featuring various chess engines from my list of favorites and the following morning I started to flip through the games.

Here is how I expected the games of Komodo 10.4 to play out as black.

  1. He contains the white bishops (probably within a rigid white pawn chain)
  2. He gradually outplays opponents, accumulating one positional trump after another

Something like this.

How I Expected Komodo 10.4 to Play the Line…

A smooth, albeit slow positional crush…

And this is mostly how the games went…

And then game this game.

Rodent Karpov Completely Outplays Komodo!

This game requires a lot of analysis to see where Komodo went wrong – it could be a case of simply “castling into it” which is why I mentioned to be very careful with your kingside in this line!

Really an impressive game by Rodent Karpov, who always seemed to have everything under control.

A New Star Emerges…

Just when we thought that Rodent Karpov was the greatest, most solid guy since…well, Karpov – he also lost a game which made him look like a complete amateur.

I created a new version of Rodent III Alekhine which I feel matches the style of Alexander Alekhine¬†much more than a previous Alekhine personality (which I created when I had a lesser mastery of Rodent’s tuning features).

The following game which Rodent Karpov lost, features several elements of Alekhine’s style.

  1. Pawn sacrifices (for the intangible imbalance of “time” – which Alekhine used to accelerate his attack)
  2. Ferocious kingside attacking (seemingly from a blue sky)

Let’s see it.

What a brutal beating to receive – especially for a guy who beat Komodo 10.4 in the same week.

I’m still testing this Alekhine personality, but as we can see, things are looking good!
