does anyone know of posts or resources where you learn how to beat the engine? I remember witnessing someone beat the engines on the icc on the 3 minute time control by blocking the position and beating the engine on time. however this seems like something else. anyone else have anything to say?

like perfect repertoires to reach good positions.

for some reason my rybka only plays suboptimal moves in the opening like d4 Nf6 Nc3... its in love with this Nc3 move.

Which engine? What are you trying to accomplish exactly? The blocked position stuff was years ago, I don't know if it still applies to modern, top engines.

Best bet for a human against a strong engine is to play at long time controls (longer the better), have extensive opening preparation such that they hopefully emerge from the opening with a slight advantage, and then play extremely well (like superhuman) the rest of the game to get a conversion. The original rule of thumb was that closed, deeply strategical positions were a human's best shot because some long-term plans and ideas could be beyond the engine's search horizon.

Another avenue to explore would be games in which the engine lost, say against another strong engine. You could look these up and try to steer the game into whichever position the engine made a mistake or inaccuracy in. Of course you will find sometimes that a position that you could easily convert against a human player is near impossible to convert against the computer.

There are a handful of videos on youtube showing wins against stockfish or whichever engine, but these are unverified. Even if a human does manage to get a win against a top engine, it would be a very rare occurrence.

Other than that, the obvious way is to lower the engine's strength. Play a weaker engine, reduce its difficulty level, lower depth, handicap, limit computer performance available to it, don't allow it an opening book, and so on.

Engines still don't understand blocked positions. I had Stockfish 7 analyze an OTB game of mine a month or so ago, and it thought I was at +1.5 or so, solely because there was a way for me to block the position with lots of space on my side, and then shuffle pieces around forever.

..but can you still get these positions against the engine?

Most people (including me) probably cannot; you need a lot of chess skill and ability to steer towards them and luck.

Exactly.

Father used to do it all the time. It's been a long time since I checked the chess website. I don't know if he still plays against the engines.

Yeah but that was a long time ago. Hence the term 'still'.

P.S. I guess it isn't nice to make fun of people's English if it isn't their first language, but Father's English was especially hilarious! : )
