Chess24’s own Jan Gustafsson has won the 19th edition of the
Bangkok Chess Club Open, a tournament he first won back in 2011. Indian GM Deep
Sengupta took down top seed Nigel Short in the penultimate round and matched
Jan’s unbeaten 7.5/9, but missed out on the trophy on tiebreaks. With Jan’s Thai
break now over he’ll be heading back to commentate live on Carlsen, Caruana and
co. in the GRENKE Chess Classic, that starts in Karlsruhe, Germany on Saturday.

The Bangkok Chess Club Open oscillates between being played
in Bangkok and in coastal resorts, but this year it was played in Thailand’s
capital city, in the Centara Grand Hotel in Central Plaza. You can replay the
games using the selector below:

The clear top seeds for the event were Jan and former World
Championship challenger Nigel Short, and for most of the event they lived up to
that seeding, despite some hiccups along the way! We were treated to some
highly enjoyable chess, with Nigel getting to open with the kind of tactic we’d
all like to play:

29.Rxe6! wasn’t
followed by the spectacular 29…Kxe6 30.Qxd5! Kxd5 31.Bc4#, but Black didn’t
survive long after 29…Nb8.

In the next round, however, the top seed almost lost to 2025-rated Thai local Poompong Wiwatanadate:

This is that second opportunity when, with two minutes on
his clock, Nigel could have played 39…Qxd2! and after 40.Qxc7 Kg6! 41.Re1 the
most brutal winning move is 41…Nxf3! Instead after 39…Rf7? 40.Ne4! White soon had a winning position, but failed to
convert.

After that Nigel got to play a legend’s namesake…

…and he produced some entertaining chess to win four games in a row. For instance:

Meanwhile Jan managed to win his first five games to take
the sole lead, but it wasn’t all plain sailing. As he later commented in the
chess24 chat, “got a bit lucky in rounds 3 and 5, but felt I started playing
better after that”.

In Round 3 Jan was close to busted with Black against Indian
IM Anup Desmukh but, with five moves to make in under a minute before the time
control, White went astray and finally blundered everything with 40.Ne2?

40…Bd8!
surprisingly trapped the rook and won the game on the spot! If 41.Ra7 there’s
41…Nc6.

In Round 5 another Indian, Grandmaster Karthik Venkataraman,
suffered a failure of his sense of danger when he played 23.Rf2?? (23.Nd4 or 23.Bd4 and White is on top):

It should be pointed out that after 23.Qxf2+! 24.Kxf2 Be6+
White isn’t saved by 25.Qf3 due to 25…Rxc2+! and the knight on b3 also falls.

Jan conceded his first draw to third seed Lalith Babu in
Round 6, setting up the showdown we were all waiting for against co-leader Nigel
Short in Round 7. The two players had dined together at the event…

…and would take part in the Thai New Year Songkran
celebrations…

…but their game was anything but a damp squib.

Jan stayed
true to his Vienna
Repertoire for Black against 1.d4
until 13.g3, a move both Vladimir Kramnik and Magnus Carlsen had played
against Alexander Morozevich:

Here Jan recommended 13…0-0 in his series, but for this game
he thought 15 minutes and decided to try something else, later commenting in
chat, “I knew 0-0 instead of Ke7 was fine, but felt like pushing my luck OTB”
(OTB = over the board).

Things got spectacular fast, as after 13…Ke7 14.Kg2 Rd8 Nigel surprised Jan with 15.Nf5+!? (he was expecting 15.Re1):

Play continued 15…exf5
16.Qh5! Rf8 17.Rhe1
(17.Bxf7! was playable, as 17…Rxf7? fails to 18.Rxc8) 17…Nc6 18.exf5+ Kd6 19.Qh6 Bd7 20.Qf4+ Ne5
21.Qd4+ Ke7 22.Bd5!
(Jan was expecting 22.f4 with some hopes of his getting
an advantage) 22…Rfd8:

Now White would be losing, if not for 23.Rxe5+! fxe5 24.Qxe5+ Kf8 25.Qh8+ and a draw by perpetual check.

Jan and Nigel were caught in the lead by Vietnamese IM The
Anh Duong, who despite a 2302 rating managed to beat two 2500+ rated grandmasters
in a row. Australian GM Zong-Yuan Zhao blundered badly with 44…Nd7? in Round 7:

45.Nc4+! bxc4 46.Rxa5
was essentially game-over.

Duong was paired with Black against Jan in Round 8, and it’s
fair to say his opening didn’t turn out so well. By move 5 Jan confessed to being out
of book, but in a position which had to be in his favour, and by move 10 the
computer was ready to throw in the towel on Black’s behalf:

Jan sensed he was close to victory over the board, and
although not going for the computer’s preferred option (he picked 11.0-0 instead of 11.Nb3) there was
only one move you could seriously question – if 13.Nxe6!? had been met by 13…Nxe6! Black would “only” have been
much worse. Jan would go on to win a fine miniature by capturing a pawn on d5
with 17.Nxd5!!

After 17…Qxb5
18.Nf6+! Nxf6 19.Qxf6
Black was temporarily a piece up, but there’s no way
to avoid the heavy loss of material. The game continued 19…Rh7 20.Qxe6+ Ne7 21.Bxe7 Rxe7 22.Qxc8+ and Jan went on to win in
25 moves.

Meanwhile Nigel had Black against Deep Sengupta and can’t
have been thrilled with how the game was going:

After normal moves for Black, White is ready to open up the
king with 34.Nxh5! That was a fate which needed to be accepted, however (after
33…Bf8! 34.Nxh5! it looks as though the game should end in a draw with best
play), since 33…Ne5? 34.Bxe5 Qxe5
35.fxg7
just left Black down a piece. As Nigel commented:

Jan therefore went into the final round with a half-point lead,
and had no problem with an 11-move draw with the black pieces against Indian GM
Dhopade Swapnil. 

That might have been enough for clear first place, but
Sengupta was soon better with Black against Philippines IM Haridas Pascua and
went on to win in 54 moves. The fate of the trophy therefore depended on
Buchholz tiebreaks, which worked out in Jan’s favour.

Nigel Short also drew his
last game and had to settle for 8th place:

So congratulations are due to Jan on winning his favourite
tournament for a 2nd time! It’s back to reality soon, since from Saturday onwards Jan
will be commentating on the GRENKE Chess Classic live from Karlsruhe and then
Baden-Baden with Peter Leko.
