Lessons from the 2017 SPICE Cup

IM Kostya Kavutskiy, Photo Paul Truong
Last week one of my favorite yearly events, the Spice Cup Open, concluded in Saint Louis, Missouri. This is a small but densely packed tournament open to about 50 players, organized by Susan Polgar & Paul Truong and Webster University. With both Webster University and Saint Louis University now fielding powerful rosters of Grandmasters, the Spice Cup had a total of 22 Grandmasters, many of them representing foreign federations, which makes the Spice Cup a great tournament for norm seekers. This year the event saw three players share first with 6.5/9: GM Lazaro Bruzon Batista and GM Yuniesky Quesada Perez of Cuba, as well as GM Darius Swiercz of Poland, currently playing for Saint Louis University. I finished with a decent 5/9 and shared the top U2400 prize with my roommate for the event, IM-elect Shiyam Thavandiran. But for Shiyam this was a much more important event, with his score he managed to cross 2400 FIDE for the first time in his career and officially secure his IM title. Bravo! Full standings, games, and photos from the event can be found here. I would also encourage readers to check out GM Alex Yermolinsky’s personal recap of the event here!

Rather than go through my own event round by round, I’ll highlight some nice tactics that decided my games:

Ruifeng Li vs Kostya Kavutskiy

White to Move
White has some nice compensation for the pawn in the form of active pieces,but it turns out there was a direct win, that Ruifeng spotted without much time on the clock. Show Solution

With so many strong players there were so many intriguing games, and after each round I would spend time playing through all the games of the previous round. After the tournament, I took some time to go through some of the more interesting games I could remember from the event. And like most players who play through games, I’m always interested to find the critical moment, to figure out at what point did the winning player find the decisive blow? Or if the game was not won, at one point did the advantageous side spoil their advantage? A lot of players analyze games like this, using the engine to point out the best and worst moves of the game. But there’s one point of analysis that I’d like to share with the readers, which is truly essential for anyone who wants to feel what chess is like at high levels. When you’re using a powerful engine like Stockfish, or Komodo, or Houdini (or even Rybka, hey no judgment here ?), it can often point out a win in under a second, and flash that dazzling +2.5 and soaring evaluation. So you might see that one of the players missed a win, but here’s the thing: don’t stop there. Don’t just look at the evaluation and think “Oh, he missed Nh5, that was winning, +4! How could he miss it?!” Investigate. Input the winning move and see what the best defense is. More often than not, a strong player doesn’t simply overlook the winning move, they often see the possibility but then miss some important resource or detail in the ensuing variations. It’s important to keep this in mind as not all winning lines are created equal. In some cases, one move wins a rook on the spot and seals the deal. But in most cases, seeing the winning move requires accurately calculating multiple variations. Strong players don’t go for lines that simply “look good” without calculating deeply. One miscalculation or oversight could lead to even a very strong player rejecting a winning continuation because they weren’t able to fully “make it work”.

So here I’ve picked out some of the most interesting segments from the event, featuring some analysis of the various combinations and lines the players might have been calculating during the game. I hope you try your hand at finding the best moves in each position. Here are two wins from one of the tournament winners, GM Lazaro Bruzon Batista: Black to play, can you see how to make use of the weaknesses in White's position?

Finally, here are two of the most interesting encounters from the event. As a brief disclaimer, please keep in mind I have no idea what the players were actually thinking at the time, I’m more or less playing detective trying to deduce what they saw or didn’t see, but nevertheless the chess is still fascinating!

dominant position, as the bishop on a8 is buried thanks to White's strong pawn
on a6. Realizing how bad the situation is, Cori starts taking risks-- Black's
last move, Na4, is a big provocation. White can either trade queens and risk
losing the a6-pawn, or grab on a7 and risk getting the queen trapped. Can you
figure out the evaluation of each? SOLUTION:} 23. Qxa7 $1 {A bold decision, as
at first glance it's not clear how White gets the queen out of a7 without
giving back material. Swiercz must have calculated accurately that Black won't
be able to win the queen without giving up a lot of material. So how does
White actually excavate the queen? The key is to resuce the queen through the
c6-square: White wants Ne5 & Rxc6, winning.} (23. Qxe7 {would secure White a
smaller edge, after} Rxe7 24. Ne5 Nxa6 25. Nd3 $16 {White has more than enough
compensaiton for the pawn, as the second knight will head to a5 and White will
eventually win the c6-pawn.}) 23... f6 $5 {Stopping Ne5 but giving White time
to find another escape plan for the queen.} ({The immediate} 23... Qd8 24. Ne5

White's three pieces easily outplay the queen.}) 24. Nb3 $1 Nxa6 {With the
knight on b3, Cori elects to give up three minors for White's queen. Perhaps a
good practical decision, as positions with material imbalance are often tricky
to play, but Swiercz's conversion looks effortless.} ({Now after} 24... Qd8 {
White is in time with} 25. Nc5 Re7 26. Nxa4 bxa4 27. Qc5 Nxa6 28. Qa5 $18 {
with a dominant position. Black's bishop and c6-pawn are critically weak.}) 25.
Qxa6 Bb7 26. Rxa4 $1 ({Now} 26. Qa7 $2 {is bad in view of} Ra8 27. Rxa4 bxa4
28. Qc5 {and the knight hangs on b3:} axb3 $19) 26... Bxa6 27. Rxa6 Qxb4 28.
Nc5 $18 {A good rule of thumb for understanding positions with material
imbalance is this: The side with the queen needs targets, whether it's weak
pawns or an exposed king, while the side with the pieces needs stability:
outposts and good piece coordination. Here, it's clear that White's position
is in near perfect harmony.} (28. Nfd2 $18 {was a bit easier, as White takes
the c6-pawn next move.}) 28... Qb2 29. Nd3 Qe2 30. Nfe1 b4 31. Bf1 Qg4 32.

pawn on b3 -- it must still be rounded up.} b3 33. Rb1 Rec8 34. Rxc8+ Qxc8 35.
Nc5 Qc6 36. Ned3 {White will pick up the pawn on b3 on the next move and
Black's counterplay will run out. Next White will play Bg2, Nf4, and take the
d5-pawn. I'm not sure whether the game ended here but in any case, Black's
position is lost.} 1-0

end up down a rook.} 34. Kh2 Rxd8 $19) ({Stockfish points out that} 29. Qxf2 {

SPICE is an acronym. Great report otherwise!

Another tremendous full of life 'I WAS THERE' missive by Kostya Kavutskiy .. we have this hopefully to look forward to for the next half century!.... however..all photo figures in "winner circle" item should have been named ..period. Finally let me note worldwide one mo' time... that the incredible fraud/deceit and jealousy in US Chess offices, executive board/editorial pages that has denied the CHESS HALL OF FAME NOMINATION TO gigantic,collossal promo chess pyramid SUSAN POLGAR (lock stock and barrel the ASTOUNDING SPICE PRO CHESS grandmaster tourney chess series instigator, the absolute reason it happens).... worldwide penned as SUSAN POLGAR CHESS DAILY NEWS AND INFORMATION uncensored.. The greatest national championship collegiate chess coach of all time... is not even worth mentioning at every possible turn.....Madame Polgar, elected by a landslide as US chess president and defrauded beyond words by truly pathetic US chess cronies/ sheer silly mediocrities ...is known as titanic by the whole chess world. Her left shoe has more value than an agency that cannot EVEN NOMINATE the greatest chess tourney director in world chess history (Mr. William Goichberg) or Grandmaster Polgar for the Chess Hall of fame...both tower above our silly US chess bureaucracy and show how ABSURD, ridiculous, really what a laughingstock bunch of clowns US Chess includes.....I PUBLICLY ASK US CHESS....Are you really going to let these COLLOSSAL GIANTS,wonderful individualistic if flawed people die without formal, ETERNALLY GRATEFUL US CHESS recognition simply because they do things their way and do not kiss US chess office boots? Thank you so much for allowing me to speak. Please ladies and gentlemen..think it over. Thank you so very much for reading. Jude Acers/ New Orleans

In reply to by Jude Acers (not verified)

Polgar sued the organization as a fiduciary. Classless and utterly devoid of any honor, much less the character and spirit of a hall of fame recognition. No one will ever forget her because her supporters overlook the simple, bare bones fact that she tried to bankrupt the organization as a board member.

In reply to by anonymous_stub (not verified)

Amidst paying the Fide world chess federation grandmaster Susan Polgar's entire legal bill/losing untold millions in potential sponsorship/engendering unimaginable hatred... US Chess found final judgment: it was discovered grandmaster Susan Polgar had done absolutely nothing wrong amidst 2,000 day vengeful harassment. FRAUDULENTLY REMOVED FROM HER (ELECTED BY A LANDSLIDE) US CHESS PRESIDENTIAL OFFICE.. She ruthlessly, mercilessly , correctly defended herself. She was just innocent. The age of the "yes sir whatever you say sir" girl is over. In the same manner MR. WILLIAM GOICHBERG , who is only hands down the greatest chess tourney director who ever lived ..is likewise denied hall of fame nomination because he does not kiss our boots. Indeed folks... We ALL do not like him so very much, Oh gee whiz...We write history as if Washington Lincoln, Franklin, Reagan , Eisenhower, Obama , the Bush family, the Clinton family do not exist in world history because after all... millions of people somewhere ,some how do not like them very much.MR GOICHBERG AND MADAME POLGAR TOWER ABOVE US CHESS MEDIOCRITY/hatred/ small timer jealousy.. THEY ARE ABSOLUTE CHESS GIANTS, CHESS IMMORTALS AND READERS YOU KNOW IT TO YOUR VERY BONES... how about the CHESS HALL OF FAME NOMINATION for both, short and snappy? Let bygones be gone.. Just sayin'... Thanks to every reader for considering the matter.Believe: the younger generation chess upstarts are never going to let us get away with this silly, pathetic, petty, absurd, stupid venom. They will laugh at us.. view US Chess clowns with myopic madness not the real deal, flawed glory that these .. our VERY BEST truly represent.... Yes indeedie, both are feisty imperfect people of course. But grand. Jude Acers/New Orleans
