Games from the 25th Space Coast Open, April 27-29, 2018

Here is our selection of games from the 25th Space Coast Open. Six games are presented. To see the available games, click on the down arrow (triangle) in the white box above the board window.

The first 3 games are the Brilliancy Prize winners, selected by Brilliancy Prize Judge IM Javad Maharramzade.

First Prize: $200 to Carlos Andretta
Second Prize: $100 to Andy Catlin. Due to work commitments, Andy Catlin was only able to play 2 rounds, scoring 1.5 points against a high expert (win) and a strong master (draw). Along with two half-point byes, this resulted in a score of 2.5, which would have been good for a tie for the third expert prize if Andy had wanted to request a zero point bye in the last round, rather then withdrawing. But his play did not go unnoticed by our dedicated Brilliancy Prize judge, IM Javad Maharramzade, who selected this game for the second Brilliancy Prize.
Third Prize: $50 to Xavier Alvarez

Next we have the decisive game by the tournament winner, Icelandic GM Hedinn Steingrimsson. With the Black pieces he convincingly topples top ranked GM Alexey Dreev to take sole possession of first place. The game receives an honorable mention for the Brilliancy Prize. IM Maharramzade said, "A very clean game by the tournament's eventual champion. To take down a player of Dreev's caliber with Black in the last round without committing any inaccuracies is certainly not an ordinary accomplishment. Dreev was not at his best in this game, not achieving anything in the opening and allowing a typical position with an isolated pawn in the center. Quickly Black was able to shatter White's pawn structure on the king-side, and Dreev's two bishops did not prove to be a sufficient compensation for that. A critical improvement to the Black's position was 34... Nh5!, freeing the other Knight from the necessity to support the Bishop on f4. White's position collapsed soon afterwards."

Then we have a fighting draw between two of the Grandmasters who tied for second place. This game was also played in the last round, and a win by either player would have given them a share of first place and a much larger prize. This was not meant to be, and after some fireworks, the game was drawn while the key matchup on board 1 was still underway.

And for our final game we have a wild attacking game where Vlad Yanovsky was on the verge of defeating IM Yunier Leyva Rivera, but in the end, the IM triumphed, enabling him to join a 3-way tie for second place.

1st Brilliancy Prize at the 25th Space Coast Open. "Study this game thoroughly
if you want to learn how to play against Botvinnik triangle structures. A
clean example all the way from the opening to the endgame. One could argue
that White could have finished the job quicker had he kept the opposite color
bishops (37.Bg6 instead of 37.Be6), but the ensuing Rook endgame with the
White King marching to take the Black's pawn on b6 is another nice
instructional piece in itself, so it doesn't diminish the game's overall value.

{Annotators: Andy Catlin (AC), IM Javad Maharramzade (JM) - brilliancy prize
judge, Stockfish (SF). Awarded 2nd Brilliancy prize. "A well-executed Bishop
sacrifice on h7 to expose the Black King, demonstrating the benefit of
delaying the castling, giving the H-Rook an opportunity to join the attack
quickly. This idea seems to get more and more popular in modern theory in many
different openings, where you see the h-pawn getting pushed to h4 very early
in the game. Black was forced to return the piece quickly, and White's finish
was energetic and efficient." (JM).} 1. e4 c5 2. Nf3 Nc6 3. c3 Nf6 4. e5 Nd5 5.

Prize at the 25th Space Coast Open. "This is to pay tribute to the fighters of
the lower sections. In a well-known line in classical Caro-Kann White employed
an unusual move order (13.Kb1, 14.Nf1, 15.Qe2 - this aggressive plan is
typically executed without spending a tempo on Kb1), but confused his opponent
enough to get a very promising attacking position by move 18. Black could have
defended better, but White was very determined in the ensuing attack and
delivered a very nice finishing shot - 30.Qg6! Black resigned a bit
prematurely, not allowing White to show the full combination: 31...Qc3 32.h6!

{This game is a real barn burner, with first Black sacrificing an exchange on
move 16 as his King came under heavy fire. Black defended multiple mate
threats until White erred, missing some key winning lines. Then came the
counter attack, and by time White returned the exchange on move 36, Black’s
attack on the dark squares was irresistible, and the game ended a few moves
later.} 1. e4 {[%emt 0:05:08]} e5 {[%emt 0:00:32]} 2. Nf3 {[%emt 0:00:06]} Nc6
