How to play like an engine !

Enignes do not need to remember either lol. Its a program

That really depends on how you conceptualize memory retention. For instance, I'd argue that any engine based on an adaptive algorithm that stores previously played positions and adjust accordingly at least to some degree "remembers" by the definition of the word.

They need to remember there openings and there variations and ther lines ect.

Those are programed in via an opening book

I see what you mean but I do not think adaptive engines exist. Hence why centaur chess is played. I am not 100% sure now but in the past i.e. one or two years ago people could automatically draw and beat engines by playing specific lines. Excuse my ignorance with computer programming, but do adaptive algorithms even exist? And if they do are they accurate?

Adaptive engines do exist. Here is a research paper about one: http://www.sciencedirect.com/science/article/pii/S0167865507002127

If people can continually draw or beat an engine by playing specific lines, as you have suggested, that engine is by definition maladaptive (i.e. it does not adapt according to its previously played games).

With respect to adaptive algorithms: they too do exist. In fact, I'm currently part of a team developing a game that utilizes an adaptive algorithm to adjusts each of five different and distinct difficulty dimensions so that it optimally fits and challenges the unique player . We hope that this will help facilitate post-traumatic brain rehabilitation, and we will be comparing the cognitive effects of training on a game based on this type of algorithm to the same game based on a static algorithm soon.

Are chess engines based on an adaptive algorithm accurate? I don't know. I'm not even sure that they are necessarily superior to nonadaptive chess engines. Chess is a game of complete available information (contrary to a game such as Poker, where the information available to the player is incomplete). As such, there is always a "best move" to be identified (or multiple equally good "best moves"). Therefore, the ideal engine - namely one that can always identify the best move from any position - does not actually need to adapt to its opponent; it can merely look at the position in isolation.

Yes but they need to remember that book. ex: usb key.

Interesting. Thanks for letting me know!

I want to beat the engine on hardest someday best I did was against only 2100.  Don't hash tables make them adaptive? 

According to survey. DeepFritz-13 vs Houdini have same strenght. OcKaSlo can defeat DeepFritz-13 without undo/take back. It means he also can beat houdini. I believe it because I've been saw with my eyes.
