I was recently triggered to investigate (finally!) a new Leela feature called WDL Contempt.

I am pretty confident I have analysed more engine games than anyone else in the world, and I truly feel that my understanding of chess has benefited greatly from it. However, some aspects of engine play and evaluation are still difficult to grasp and internalise. I came across an instructive example of this while analysing a line of the Classical Pirc with 6…Nc6.

In the next couple of posts, we stop in amazement to look at a virtually unknown idea in the Austrian Attack with some subtle and venomous points!
