Reversi 10x10 Championship
  • beppi at 2007-06-08

    WOW!! Thank you to all for the great tournament…. I WON!! I can't believe it!

    I started this tourney just with the dream to remain in 1st division, but from game to game I was going on very good. I had some very interesting game, and some lucky one.

    At one certain point I saw that klaashaas, who still had finished only one or two games, was going to have lots of points at the end of the tournament, together with alkosan and Detasio. Klaashaas anyway was the most dangerous and he destroyed me in his game, he had to lose 2 games and looked to be ahead in almost all of them. I was really convinced to lose… yesterday I found Thierry and alkosan winning on him (alkosan from the same country, very fair player). An incredible surprise!

    The games:

    Against klaashaas I didn't have any chance. He simply crushed me without hope. Congratulations.

    Against Detasio I succeeded in closing him in the opening, and quit the game with a very risky 60.h10. I'm very happy of this game. Maybe Detasio could avoid 63.c7, but I don't know if there was any other good choice for him.

    With alkosan it was very close. Again, I succeeded in closing him but I had to make big sacrifices, starting from 60.I2, and right after that I found that alkosan was playing a great parity game with black. I had to open on the right side and, after that, go with sacrifices and openings on the left side. Very hard.

    With Thierry I was in a bad position and decided to take the edge and just go for mobility. It was not working, the edges became 2, I was absolutely dead when I had to get the 3rd edge, but I found a very tight solution near the end, at 73-75-77. Pheew! A very lucky game here, Thierry should have won.

    With Jan De Graaf I went for the center. I saw that he considers very important having few discs, so I just tried to get the center, no matter for the number of discs, and it was the right strategy. Positional victory.

    With CloD I got a similar strategy, get the center, but I had to manage with a huge edge on the right side, that was going to be very bad for the endgame. I had to take some very difficult decision, that took me a lot of time, between moves 50 and 70. Certainly these moves of the midgame were decisive here, and the final kill was made by taking a diagonal, thanks to a good play on the left side.

    Against Jonas it has been another mobility game, in which I had the luck to take off some access to him and get him. Fortunately I had a good opening and I found some tempo on the right side. Although the game seems dominated, I was lucky here.

    Against unsusto I really could lose. I made a horrible error at 56.f8, and this being already in a losing position. From that position, going on, I think that unsusto didn't play as he is able to do and I got the match. The sequence between 55 and 75 should have taken unsusto to my resign, instead.

    Against Marco I'm still playing but the game seems really won, I'll take the risk :-). I was ahead in this game after the opening, I had to think a lot on how to complete the east and north edges, during the midgame, but suddenly I found myself with Marco's white parity too strong for the mobility I got until then. Finally, the sequence 73-79 was the key to get the parity. But it has been very risky and with Marco as I knew him a few years ago, he would not let me get it.

    Thanks all for the fantastic tournament :-) It was a real fun! Now, it's some other one's turn :-)

    He, he. I've said it before and I'll say it again: you're a little underpretentious Beppi. Can anyone tell me how I was supposed to win that game???

  • Roel at 2007-06-12

    I believe black was ahead all the time.

  • beppi at 2007-06-14

    Taking edges in R10x10 is much more dangerous then in normal R… here I got even 3 edges! After 46. I had 2 edges and white had 2 tempos on the left and, in case of lack of tempos, could even have chosen a different line to try to play for parity around J1. Thanks to F8 I could avoid to die immediately and reach 64, but who would have bet 1 cent on the next move?

    I forgot now many themes of the games, but currently I cannot understand white's choice to lose a tempo with 67.d10: maybe he could play e10 before, trying not to lose that tempo. After that, I found a miraculous sequence that incredibly avoided any strange influence and close the game. :-)

    I still think that I was lucky :-)

  • beppi at 2007-06-14

    Obviously it was 59.F8 and white lost one tempo with 68.g10 (the successive move) :-)

  • Thierry at 2007-06-14

    Yeah, 68.g10 probably was not that great. I just felt that 68.e10 69.d9 looked nasty since I did not have access to d8 and so just tried something that looked a bit more complicated… Still think I was in bad shape though. The North West was really looking bad…
