Gambit lines engine vs engine Familiar with these gambit lines?I have my own books for analysis...those I cannot post,but you may be interested in downloading other computer vs computer book lines for comparison analysis in the future: * Albin Counter gambit * Benko gambit * Blackmar-Diemer gambit * Blumenfeld gambit * Budapest gambit * Caro-Kann Fantasy gambit * Caro-Kann Rasa-Studier gambit * Danish gambit * Dutch Defence Korchnoi gambit * Dutch Defence Staunton gambit * Elephant gambit * Evans gambit * Fajarowicz gambit * Falkbeer Counter gambit * Four Knights Belgrade gambit * French Milner-Barry gambit * French Wing gambit * King’s gambit * Latvian gambit * Lisitsin gambit * Petroff Cochrane gambit * Ponziani Counter gambit * Ruy Lopez Hector gambit * Ruy Lopez Marshall gambit * Ruy Lopez Schliemann/Jaenisch gambit * Scandinavian Mieses gambit * Scandinavian Icelandic gambit * Scandinavian Portuguese gambit * Scotch Goring gambit * Scotch gambit * Semi-Slav Anti-Meran gambit * Semi-Slav Marshall gambit * Semi-Slav Anti-Moscow gambit * Sicilian Rubinstein Counter gambit * Sicilian Smith-Morra gambit * Sicilian Wing gambit * Slav Tolusch-Geller gambit * Tarrasch Defence Marshall gambit * Tarrasch Defence Von Hennig-Schara gambit * Trompovski gambit * Two Knights Fried Liver attack * Two Knights gambit * Two Knights Traxler gambit * Vienna Game Frankenstein-Dracula gambit * Urusov gambit Some test game results using the book: StockFish 050615MZ 64 2015.06.10 Komodo 9.01 64-bit Core i7 1-0 Test GambitLines, Blitz:3' (52) An absolute shocker was the following game, in which Stockfish was able to beat Komodo in just 19 moves! 1. e4 e5 2. Nf3 Nc6 3. c3 f5 4. d4 fxe4 5. Nxe5 Qf6 6. Nxc6 dxc6 7. Nd2 Bf5 8. g4 Bg6 9. h4 Qe7 10. Nc4 O-O-O 11. Qa4 Kb8 12. Na5 Rd5 13. Nxb7 Kxb7 14. Ba6 Kb6 15. Be3 Nf6 16. Bc8 a5 17. Qc4 Rb5 18. a4 Qe8 19. b4 The Frankenstein-Dracula gambit is one of my favorites, it leads to absolutely obscure and murky play. Here is one example: Komodo 9.01 64-bit 2015.06.10 SF050615MZ 64 Core i7 0-1 Test GambitLines, Blitz:3' (31) 1. e4 e5 2. Bc4 Nf6 3. Nc3 Nxe4 4. Qh5 Nd6 5. Bb3 Nc6 6. Nb5 g6 7. Qf3 f5 8. Qd5 Qe7 9. Nxc7 Kd8 10. Nxa8 b6 11. Qf3 Bb7 12. d3 Bxa8 13. Ne2 Bb7 14. h4 f4 15. Qh3 Bh6 16. Bd2 Nd4 17. h5 Nxe2 18. Kxe2 Nf5 19. Kd1 Qc5 20. Rf1 Kc8 21. Bc3 Rf8 22. a3 a5 23. Bd2 gxh5 24. Kc1 Qc6 25. Qxh5 Qxg2 26. Qd1 Nd4 27. Kb1 Bf3 28. Qe1 Bc6 29. Bc3 Nf3 30. Qe2 Bg7 31. Ba2 h5 32. b4 h4 33. bxa5 h3 34. axb6 Rf5 35. Bb3 h2 36. d4 exd4 37. Qa6 Kd8 38. Bb4 Nd2 39. Bxd2 Bb5 40. Qa7 Qxf1 41.

Ka1 Rxf2 ------------------------------------------------ Just another learning tool as one moves up the rating ladder... Analyzing your games,including gambit lines from the standpoint of engine vs engine has considerable learning advantages.You can see,for example,which gambit line has the best game results between the two engines set on various levels from blitz to longer time controls.Then copy those results in your notebook with your own footnotes and then eventually use them later on in any of your GK games.There is nothing illegal about studying books and computer vs computer analysis,taking notes,observing the best lines and more....then eventually using your test results in your own book or one designed for you from some other source like Hiarcs or one above.Its only illegal to use a chess playing program to play against your opponents.But not using custom opening book research analysis prior to any games corresp or OTB. That is where the Houdini Opening book,Rybka,Hiarcs and the gambit books(above) come in handy.Much of this thread is not designed for the 1300 player or below in rating,but eventually over the months or years as those players improve,they may want to begin their own book line research and this thread can help. deeper_insight 30-Oct-15, 14:39 [ report abuse ] More engine learning tips.... Just a tip on engine vs engine play when comparing the results and using the final analysis in your future games.Why am I mentioning this?Because engine vs engine play can be a huge learning experience later on down the line in your studies.The analyzed results should be noted and stored away in your records for future usage.Komodo and Stockfish are just examples for analysis.There are many more engines that can evaluate and be tested beyond the top two.And do not forget that the same engine can play against itself,not simply against another type of engine.Seeing how an engine dismantles a pawn cluster or opens up a file,prepares an x-ray attack and more is very useful to your studies in chess.GM's do it all the time.There is nothing incorrect,illegal or immoral using engines in your studies before a game or after a game on GK or elsewhere.Its only wrong to use the engine DURING an actual game to play out the moves....so please note the difference!I have personally learned much from Houdini and the other engines in my possession.One of the things I have learned was how to empower my Rooks at earlier stages of the game in open/semi open files...both in regular out of book games and irregular games.Previously,I had kept my Rooks more inactive in the midgame,leading to more draws. Komodo is best at evaluating middlegame positions accurately once the tactics are resolved. Stockfish seems to be best in the endgame and in seeing very deep tactics. Houdini is the best at blitz and at seeing tactics quickly. Rybka is just obsolete. Komodo’s assessment of positions is its strong point relative to the other top two, Houdini best for tactics, Stockfish for endgames and whenever great depth is required. Both Houdini and Stockfish overvalue the queen, Komodo has the best sense for relative piece values I think. Komodo is also best at playing the opening when out of book very early. Closed openings (French, Classical KI) are not ones that engines play as well,so some judgment must be used to know when to trust the engines and when not to do so.This is a very important fact to remember,so burn it into your memory. One final note: Some chess sites like ICC allow computer usage,especially in blitz.This is a good test ground to match engine wits against others and tabulate better play conclusions.One must inform ICC ahead of time,however that you will be using silicon,else you will be ejected off of the site or they give you the option to place a "flag"by your handle name to illustrate computer usage....nice!In reality,they have special analysis software to detect program usage through parallel program comparison matches from their system to your play and draw conclusions after a number of games are played.
