Et Mortuus Est Rex
Posted: Fri Jul 03, 2020 10:15 pm
Hi,
The title is in Latin and it means The Dead King ....
I started a series of chess tournaments playing the chess engines rated in the CCRL from 2400 Elo and higher ....
Each tournament consists of 7 engines and myself playing 2 games against each other ....
The first engine I played is Simplex 0.9.8 x64 running on my i9 overclocked monster PC ....
Time control is 40 minutes + 20 seconds increment ....
The only advantage I use against the engines is that I am not entitled to the above mentioned time control meaning that my thinking time is infinite but usually I think around 2-5 minutes on a single move ....
Simplex 0.9.8 went down in the 2 games
Note that I steer the chess engine to a specific opening line that is comfortable for me,in this case the Hedgehog of the Symmetrical English which I am pretty much familiar with also when I play the Sicilian Kan variation ....
Here I tricked Simplex to take the pawn on the b6 square with it's queen drafting it away from the white kingside ....
It was a risk and somehow I bluffed but it played along as I generally anticipated ....
All in all Simplex is a good playing chess program but it lacks tactical abilities and has a noticeable problems with positional understanding of the game ....
The game is annotated by Deep Rybka 4.1 SSE42 ....
Enjoy ....
