Due to the absence of strong Man versus Machine competitions Rebel company wants to introduce a new initiative called The Monthly GM Challenge.

The goal is that REBEL plays one LIVE tournament game against a grandmaster once a month. Live coverage including Rebel analysis via the Rebel Home Page.

  • $500 if the grandmaster wins against REBEL.
  • $250 for a draw.
  • No prize money in case of a loss against REBEL.
We challenge every chess player with an official FIDE grandmaster title to take the bite and play our program. You can contact us by email at Mail to REBEL. Acceptance of entries is done in the order we receive them.

The second game is scheduled on Saturday July 3, 1999 against GM Ariel Sorín.

    A memorable game

    1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 0-0 6.Bg5

    { White uses the well known Averbach variation against the King Indian Defence played by Zapata. His purpose is to avoid 6..e5, which would be punished with 7.dxe5 dxe5 8.Qxd8 Rxd8 9.Nd5! winning material. }

    6..c6 7.f4 { begins an agressive game }

    7..Qa5 8.Qd2 e5 9.fxe5 dxe5 10.d5 { Closes de Bg7's diagonal and gets space advantage }

    10..h6? { Risky castling weakening, looking for counterplay } 11.Bxh6 Bxh6 12.Qxh6 Nxe4 13.Rc1 Nbd7 14.Nf3 Ndf6 15.Nd2! { 15.0-0 was not possible due to 15..Qc5+. Textula tries to change the better black piece and project a very depth combination }

    15..cxd5 16.0-0! { Conceptual sacrifice, betting on pieces development }

    16..Qb6+ 17.c5!! { A new pawn sacrifice, in order to misplace black pieces. If black accepts the bet with 17..Qxc5+ then 18.Kh1 Qd6 19.Ncxe4 Nxe4 20.Nxe4 dxe4 21.Nc4 Be6 22.Rf6 Qe7 23.Qg5 +- }

    17..Nxc5 18.Rxf6! { Removes violently the latest king defender and brings more pieces to the attack } 18..Qxf6 19.Nxd5 Qd6 20.Bc4 b5 { Loser, but the position was hopeless, now we will assist to a tematic and nice outcome }

    21.Ne7+! Qxe7 22.Qxg6+ Kh8 23.Qh6+ Kg8 24.Rc3! { The reserved piece kill of the game }

    24..Bg4 25.Qg6+ 1-0 { Black resigns. If 25..Kh8 26.Qxg4 threatening the mortal 27.Rh3+ }
