ROTFL - sorry for the subject line .. - hope I can still post sth of at least limitted interest. 1.) Toying around with Fruit 2.1 currently - that would be change no 1 - now there is a free open source amateur engine that is just as strong as the strongest commercials on ordinary PCs . No, that's no news anymore. But just as others I had to see it for myself, despite various previous reports. 2.) Second one is about openings. Dann Corbit built an interesting book for Fruit IMHO. I guess it's completely automated, but he chose a good point to leave book, usually about 2 or 3 moves before known theory ends, with something like 10-15 moves of opening theory on average. And in several games Fruit finds interesting and valid alternatives to grandmaster analysis. Just a little example ( my sources might be slightly dated as I don't play the Ruy from either side).

Nb3 {3s} A famous line of the Open Ruy known to be busted (11. .. dxc3?!) - that's Kasparov-Anand, New York PCA WCh (10) 1995, 14. Bc2 is ! and 15. Nb3!! . NCO and ECO have a look at 15. ...Nxb3 and 15. ...Rd8 and prove a clear white advantage. Fruit, ever sceptical, just takes on e5 (and how come this move doesn't even get mentioned?). [D]r3kb1r/2p3pp/p1n1p3/1pn1P3/8/1Nq5/P1B2PPP/R1BQ1RK1 b kq - Whatever the absolute thruth, Fruit got very decent compensation for the exchange in the game and in fact had little trouble to reach a major advantage against the world champion, who lacked counterplay and pawn levers. Most moves even looked very obvious. Similar happened in several other Fruit games I have watched. I am getting more and more sceptical of classical opening books. -- Unrelated, still .. - Fruit probably blew the huge advantage it reached later as it allowed transformation to a drawish endgame. [D]5b2/8/5k2/p4r2/Bp3K2/2p5/P4P2/4R3 w - - Here Junior played 49. Kg4 which should be ?? , while 49. Kg3 probably holds. I can only explain with wrong knowledge about bishop with opposite colour endings, and it's certainly not the first example from Junior I have seen covering this theme. I don't think a human would consider giving up the pawn on f2 . Everything with a huge grain of salt as usual :) .
