When I started playing again after a break of some 8-9 years, my opening choices were driven by a fervent desire to do something different to what I had done before, and by some strange feelings of nostalgia.
A little while back, I published some blog articles and some videos on Dragon’s creative 5.Qd2!? idea in the Pirc (https://matthewsadler.me.uk/openings/a-stunning-dragon-idea-against-the-pirc-5-qd2/ and https://youtu.be/DuFfJwBgMD8 to start you off!)

Getting Leela to analyse and play in the style you want! Part 3 – More adventures in Crazy Leela’s GROB Semi Slav?!?!

n this post, I continue my adventures with Crazy Leela’s Grob Semi-Slav! After being rather marmelised when taking the gambit pawn, I decided to refuse the offered pawn in a couple of games. Let‘s see how that went! A video of these games is available from my Silicon Road YouTube channel: https://youtu.be/EK9_iA63Nvo while engine analysis of these games is available from the usual place: http://cloudserver.chessbase.com/MTIyMTYx/replay.html

In a previous post, I described how to set up the new Leela feature called WDL Contempt (described here by the Leela team: The Lc0 v0.30.0 WDL rescale/contempt implementation – Leela Chess Zero (lczero.org)) In this post I look at one of the opening discoveries I made using a Leela optimised to search for promising lines against a prospective (fictitious!) opponent rated 400 ELO points below me! (A roughly 2700 ELO vs 2300 ELO scenario)
I was recently triggered to investigate (finally!) a new Leela feature called WDL Contempt. This feature was beautifully described in this blog article (The Lc0 v0.30.0 WDL rescale/contempt implementation – Leela Chess Zero (lczero.org)) by the Leela team, but the implementation is slightly fiddly so you need an hour of quiet time to set things up right.
