Who's beaten J-Chess?

  1. Jun 28, 2005 #1
    This online Java program has royally destroyed me too many times to count. I'm not a die hard chess player, but I like to think that I have some talent. Here's the link to the page where you can play the prog. If you beat it, I wanna see a screen shot! Who can do it or who has done it?

    The game has no repetition draw rule... the comp is doing the same two checks forever.

    The computer is pretty good. I wasn't able to beat but I think I was able to keep it on it's toes. I have a friend who would probably be able to beat it. If I went at it long enough I could probably do it as well.

    I just forced a stalemate draw, not mate yet though.

    How do I post my picture?

    Edit: The game seems very 'piece cost' intensive, not too difficult to beat.

    What a piece of crap program.. after my fourth move, it's not responding.

    Funny, I sacrificed my queen but I guess most players would fall for that, my dad did that to me a lot. His teaching me is probably why I do it myself.

    I noticed that. It made a queen trade with me about half way in.

    It likes to accept Queen's gambit, and try to save the pawn. :smile: If only I knew enough chess to really take advantage of that!

    I got beat up in the King's Gambit (playing white,of course),even though it was still even half way through.

    I played queen's gambit (thanks Hurkyl!)... it does take the pawn. It also likes to Fianchetto.

    I don't know how to attach a picture, but this was how it went:
    1.d4 d5 2.c4 dxc4 3.Nf3 Be6 4.e4 Nf6 5.Nbd2 b5 6.Qc2 Nbd7 7.b3 cxb3 8.axb3 b4 9.Bb5 a5 10.Bc6 Ra6 11.h3 a4 12.Rxa4 Rxa4 13.bxa4 b3 14.Qc3 b2 15.Bxb2 g6 16.d5 Bg7 17.dxe6 fxe6 18.Ng5 Nh5 19.Qb3 Bxb2 20. Nxe6 Qc8 21.Qxb2 Nhf6 22.Nf3 h6 23.Ne5 Rh7 24.0-0 g5 25.Rd1 Rh8 26.Rxd7 Nxd7 27.Bxd7+ Qxd7 28.Qb8+ Qc8 29.Qxc8#

    Anyone do it in less than 29? :smile:

    I'm impressed. Can you send the notation for your game, or any advice to beat the program? I really want to get revenge. This is getting embarassing.

    Most chess programs are better at positional games than on tactical play.
    Thus, you should learn to play risky and "mess up" the board with loads of threats and counter-threats.
    Playing King's Gambit or Morra Gambit and the like as white is a good choice.

    Haha, I just played it again, and literally destroyed it.. Here's the stuff:

    http://img173.echo.cx/my.php?image=jchess26hf.png
    1) d4-d5 // 2) c4-dxc4 // 3) e3-b5 // 4) a4-Bd7 // 5) Na3-bxa4 // 6) Bxc4-Nf6 // 7) Nf3-e6 // 8) O-O-Bb4 // 9) Bb5-Bxa3 // 10) Bxd7-Nxd7 // 11) Rxa3-Nb6 // 12) Ne5-g5 // 13) Nc4-Nd7 // 14) Nxb6-Nxb6 // 15) e4-O-O // 16) Qh5-Qxd4 // 17) Qxg5+-Kh8 // 18) Rg3-Nc4 // 19) Bf4-c6 // 20) e5-Qxf2 // 21) Rxf2-Rg8 // 22) Qf6-Rg7 //
    23) Qxg7++


    My advice: Forget about piece value (that is, make sacrifices.. especially pawns), and simply forge an attack.. Basically, blindlessly advance towards the King; it works! Also, remember to abuse the fact that the programmer allows for the King's pawn structure to be broken.

    Most mediocre chess programs tend all too easily to be "greedy" (i.e, accept whatever bait/sacrifice given them).
    Thus, I concur with Knavish (and with my own earlier advice)

    Knavish, your move 5 is incorrect. It isn't possible for the move Nb3 at that time.

    I meant Na3.. Some of the notation may have little errors--it's not all that fun typing it up.

    Do any of you play online? Yahoo Games perhaps? I need some good competition.
