{They say what happens in Vegas, stays in Vegas. Cameron Wheeler, 17, proves
that slogan false: he has brought home oodles of rating points from Sin City
each of the past three years. The North American Open has been kind to Wheeler,
who earned his final two international master norms at the tournaments in 2015
and 2016. In 2017, he defeated a whopping 5 players rated over 2400 FIDE and
narrowly missed out on a GM norm. Wheeler's eighth round victory over fellow
teenage IM Nicolas Checa is the type of game that is frustratingly
incomprehensible. Black never did anything egregious, so how was the game so
one-sided?} 1. c4 Nf6 2. Nf3 c6 3. Nc3 d5 4. e3 a6 5. h3 {[#] I believe the
game continuation to be a surprisingly challenging move order for Black to
deal with, particularly if you are unfamiliar with the nuances of the position.
} (5. d4 b5 6. b3 Bg4 {has been seen thousands of times, including in Checa's
seventh round game where he had White. Black is happy to get the bishop
outside the pawn chain and trade it for a more active piece.}) 5... e6 ({
Expanding on the queenside looks similar to the analysis after 5. d4, but a
vital difference is that the light-squared bishop struggles to find comfort.
In a rare game in this line, White crushed his opponent:} 5... b5 6. b3 Bf5 7.

decision to make. On one hand, Black gains space and can develop the knight to
c6. However, this is the second time this pawn has moved and, more importantly,
Black gets stuck with an isolated pawn.} ({Especially since the pawn is
committed to a6,} 6... dxc4 7. bxc4 {is quite bad for Black. White's center is
strengthened and there are holes to exploit.}) (6... Bd6 {was the response
chosen by GM Dragan Solak against Magnus Carlsen at the 2014 Olympiad. It may
result in passivity, but it forces White to bring the action.}) 7. cxd5 exd5 ({
Avoiding the isolani is worse than accepting it, as after} 7... Nxd5 8. Bb2 {
Black's kingside development is halted.}) 8. d4 Nc6 9. Bb2 {A good lesson in
retaining the tension. Capturing on c5 would allow Black to develop his bishop
in one turn.} Bd6 (9... cxd4 {does not save Black a tempo.} 10. Nxd4 Bd6 {
Not only is the knight well-placed on d4, but now} 11. Nxc6 bxc6 {is favorable
for White, since the pawn on c6 is an easy target. In retrospect, this may
have been easier to play.}) 10. dxc5 Bxc5 11. Bd3 O-O ({The enticing} 11... d4
{may rid Black of his isolani, but the open position favors White, whose
bishops are superiorly placed.} 12. exd4 Nxd4 13. O-O O-O 14. Ne4 (14. Na4 {
is also excellent.}) 14... Nxe4 15. Bxe4 {with a large advantage.}) 12. O-O {
[#] Just a dozen moves into the game and Black is in grave danger. How can
this be? Material is level, no pieces are immediately hanging, and there are
no imminent checkmate threats. While this is all true, what can Black do here?
Every candidate move has a substantial drawback.} Re8 ({Rooks love (half) open
files. This is incontrovertible. Yet, given the current dynamics of the
position Black is better off putting his bishop on e6, which blocks the e-file
and limits the productivity of a black rook on e8. Connecting the rooks with} 
12... Qe7 {was more flexible. Black can figure out the rook's square of choice
in the future.} 13. Rc1 Be6 ({A trap has been set, and Black can easily fall
into it:} 13... Rd8 14. Na4 Ba7 (14... Ba3 15. Qe2 {is promising.}) 15. Bxa6 $1
{when White snags a pawn. If Black tries to counter with a bishop sacrifice of
his own,} Bxe3 16. Rxc6 $3 {and White earns two minor pieces for a rook.}) 14.
Na4 {(14. Ng5 is also interesting)} (14. Ng5) 14... Bd6 {favors White, but
there is a lot left to prove. In fact, this feels like the most stubborn
defense.} ({Trading off the powerful bishop is more useful in theory than in
practice, for} 14... Ba3 15. Bxa3 Qxa3 16. Nc5 {is uncomfortable for Black.}))
(12... Be6 13. Ng5 {is an unwelcome sight from Black's point of view. With
tactics threatening to remove the guard of h7, Black is forced to part with
his bishop pair and weaken his kingside in the process.}) 13. Rc1 ({
Undoubtedly tempting is} 13. Na4 {but the offside knight helps Black obtain
counterplay in the center. White certainly remains better, but the advantage
can quickly deteriorate.} Ba7 14. Rc1 Ne4) 13... Ba7 14. Ne2 ({In this
structure it is often best to seize control of the c5 square, though here} 14.
Na4 {again runs into} Ne4) 14... Qd6 ({When left with an isolated pawn, it is
important to utilize it. Doing so generally requires an active knight
supported by that pawn. This may seem counterintuitive, since the knight was
previously defending the weakness. However, sometimes the best defense is
creating problems for your opponent so that the pawn is immune.} 14... Ne4 {
is certainly best. White needs to tread carefully, lest the tides turn. The
following continuation is a good example of how Black can counterstrike} 15.
Nf4 ({Nearly a century has passed since Aron Nimzowitsch penned The Blockade,
a masterful book that systematized his insights on dealing with various forms
of pawn chains and passed and isolated pawns. Blockading an isolani is a
well-known principle, and knights are the best piece to use. However,
currently the d-pawn is not threatening to be pushed, so attacking it is more
worthwhile than stepping in front of it.} 15. Ned4 {induces a capture on d4,
after which Black will play moves like Bb8 and actually gain an initiative on
the kingside.}) 15... Bf5 16. Bb1 (16. Nh5 f6 17. Nh4 Be6 {and after 18. Nf4

Ne4 {because White immediately wins no less than a pawn with either 16. Nf4
Rd8 17. Qxd5 (if 17...Qxd5 18. Nxd5 Nxf2 19. Rxc6! is a powerful shot that
secures two minors for a rook) or 16. Bxe4 Rxe4 17. Nc3.} 16. Nf4 (16. Bxe4

endless pressure where your opponent seems to have countless strong plans and
you have just a few non-losing moves.} ({17... Nxd4 18. Bxd4 Bxd4 19. Qxd4 is
better for White, but requires a difficult grind to secure the full point. It
is common practice for players with an isolani to jettison the weakness in

chances. Psychologically, a nearly impossible move for a human to play is}

our nature to voluntarily open up the long diagonal with a bishop staring down
our king. Yet, Wheeler would have no means of immediately exploiting the airy
kingside. Without the time to form a battery, Black gains a vital tempo
compared to immediately trading everything on d4 (say after 18. Qd2 Nxd4 19.

d4 himself, in the line 18. Nxc6 Bxc6 19. Ne2 would be absolutely necessary to

the highest levels of the game, one inaccuracy can lead to an irreversibly bad

your opponent's positives rather than to eliminate your own negatives. Not
every threat can be thwarted, but converting is a challenge when the path
