Heading into the final round at the Barcelona Sants International Open GM Rinat Jumabayev (KAZ), GM Daniele Vocaturo (ITA) and GM Leonardo Krysa (ARG) were all tied on 7.5 out of 9. However another 11 players were just a half a point behind the three leaders leaving the final round with must win games all the way down to board 7 in order to stand a chance of being on the podium.
In the tenth
and final round, top seed GM Jumabayev drew black against the number 14 seed GM
Krysa. Meanwhile GM Vocaturo also had black against GM Svetushkin (MDA). So,
only one of the three leaders had the white pieced.
Before we
look at the outcomes of the top boards, let’s pause a moment and look at the
the two protagonists from our previous blog from the Saints Open…
Unfortunately
young Leon Luke Mendonca (IND) faltered in later rounds, including a loss in
the final round to finish on 4.5 and miss out on his first IM norm. But,
remember his name for the future as he has many years of superb chess ahead of
him.
If you
recall, Mendonca’s opponent in the second round was the third seed, GM Siman
Agdestein (NOR). GM Agdestein recovered through the tournament to eventually
win on board 8 in the final round, finishing with a respectable 7.5.
Back to the
business end of the final round, board 1 was the last to finish, allowing both
players to calculate their odds of winning, should they make a draw. Boards 3,
5 and 6 all drew to finish with 7.5. Including winners from as low as board 15,
we now had 12 players on 7.5 already.
FM Julian
Martin (GER) on board 7, GM Jan-Christian Schroeder on Board 4 and GM
Sverushkin on board 2 all won to go 8 out of 10. That relegated GM Vocaturo to
join the 12 others on 7.5 out of 10.
That left
the marathon on board 1 where GM Jumabayev converted his Kings Indian into a
won rook and pawn endgame with black to take a clear win on 8.5 out of 10.
I leave you
with a detailed look at this tournament winning game…
