Oh, I'll get hold of it later, but not going to be jumping thru hoops to get it quickly.
This is what the "free' Stockfish does to commercial Engines like Komodo and Houdini.
Soon, there will be no motivation left for the commercial Engine developers and fresh young talent graduating from Engineering Colleges will avoid getting into this line.

I remember a time when I was paying over $100 for Chess Genius, MChess, Rebel in the day and I gladly did cause I wanted the program. Open source competition & prices have gone way down. We're in the golden age of computer chess BUT it's getting so that majority of the programs have similar styles. It never used to be that years back. I remember when ICC used to be a manual (C) paradise, now it's Dante's hell. You could on there and play crafty who was always open to us,ferret, wChessX, NowX, ban and other (C) manuals who had different programs with different styles and we would play each other for hours and discuss the game, evals, shoot the poop, it was a blast. Don't even waste your time now unless you're testing your homebrew.

Good, tb support and my defeat against your program, in the last ICFB, are good enough selling points.

I notice in the purchase page:

"Compatible with all versions of Chessbase (CB 8, CB 9, CB 10, CB 11, CB 12, CB 13)"

I don't imagine there'll be any problem under the Fritz interface either. And speaking of the CB platform, what's the legal status of using Komodo in the engine cloud?

When I was 13 or 14 years old I bought a chess computer for 500 guilders and it cost me at least a year to save money for it.

A good chunk of change for a 13-14 year old and certainly would cost you more now. I had a few stand alones. They were a blast but then I started seeing Fritz 1, 2, what is this and here we are now where they can destroy any human being alive.

I do not think that the developers of stockfish are communists and I expect to see in the future something that is stronger than stockfish.

First things that developers should know in order to get success is to understand what are the main factors for the strength of stockfish.

It can be done by the following way:
take stockfish and start testing simplifications that do not reduce too much elo.

The rules can be that it is better to remove 10 elo for a simplification that reduce 100 lines of code and use SPRT to make sure that you do not remove more elo per line of code(maybe we can even be more aggresive in reduction and decide that we accept reduction of less than 1 elo per line but I think that it is better first to start with allowing only small reductions in strength per line).

Hopefully if you do it you will get something that is more than twice smaller than stockfish and not more than 200 elo weaker when every line is important based on testing because all the tries to remove a line without making it clearly weaker fail.

It can help us to know the important code of stockfish that makes it really strong.

Yes, it works with Fritz. I don't know any reason it wouldn't be ok to use Komodo in engine cloud, but I'm not very familiar with that.

What is your opinion (or anyone else on SF team) as to what makes it strong, other than things in common with the Ippos? I can't figure it out; it seems to me that SF does many things wrong, yet it is still super strong.

I don't think it is about the lines of code, but it is about the idea behind the code.

An expert in ippos and sf is wanted. Komodo probably make many things right yet still weaker than sf :) . What are some of the ideas in Komodo that are not in sf?
