"Busts to the Bust:" Contest Winners

Back at the end of July, we published Elijah Logozar’s provocative polemic, “A Bust to the Smith-Morra Gambit.” We also invited readers to submit their responses, or “busts to the bust,” in a contest sponsored by US Chess Sales and Chessable. Thanks to both of our sponsors!

Three submissions came in before the August 15th deadline, all of which are published below. (A fourth arrived too late to be judged.) While Logozar responds to all three, only two prizes could be awarded. The winners of the contest are: 1st prize – A $50 Gift Certificiate to US Chess Sales Winner: Pranav Nagarajan 2nd prize – A one year PRO membership at Chessable.com Winner: Daniel Jones
Before getting into the details of each submission, here is Logozar’s overall response to the challenges to his idea.
I would like to thank the CLO readers for submitting their attempts to disprove my anti-Morra analysis and for taking it seriously. Pranav analyzed one of my recommended lines to a draw. My claim is that Black was pressing on the way and is the only one who had serious winning chances. With precise defense White is able to hold a draw, but it is not easy. Black can always draw by perpetual check at will. In his chess.com blog post, Daniel claims that my claim of refutation was exaggerated. I’d argue that refutation has multiple possible definitions, and I was operating under the one that means “prove to be substandard or conceptually incorrect.” My claim is that Black is at least slightly better in all variations, not that White loses by force. Brian claimed that I’d underestimated White’s chances in the 6.Bf4 a6 7.Be2 variation. I believe that White’s chances are only practical as objectively White doesn’t have sufficient compensation for the sacrificed pawn.

{First of all, I'd like to clarify something. In the variations that follow,
White has to make numerous only moves while Black has a draw in the pocket. He
is the only one who can play for more and who might have a theoretical
improvement which consolidates into a static advantage. My claim was not that
Black wins by force in the Morra, but that he has at bare minimum a small
advantage. Some small advantage positions are defensible, and in this case, I
agree with you that this is defensible for White. Just because I found the
method for White to defend against Black's initiative/small advantage does not
mean that it doesn't exist. Several Stockfish "0.00" suggestions (depth 30+)
failed to equalize/hold for White, if that says something. On to the
variations.} 1. e4 c5 2. d4 cxd4 3. c3 dxc3 4. Nxc3 Nc6 5. Nf3 e6 6. Bc4 Nge7

0-0, ...a6, ...b5, ...Bb7, ...Rc8, ...Na5) White won't have any compensation
for the sacrificed pawn. White is forced into immediate tactical operations to
try to prove that he can use his lead in development before it disappears.
I've attached 'only move' symbols for White when relevant (Black has a lot
more room for error and has more playable alternatives). Fail to find the only
move when Black is up a pawn, and the compensation disapears. Fail to find an
only move when Black is not up a pawn, and Black will have (as a minimum)
verifiable =+ and in most cases more, not counting the initiative that he
already had. You've already seen the refutations to White deviations from only
moves in my course so I won't include the early refutations and cut straight
to the critical positions.} d6 9. Bg5 $7 Qd7 10. Nbd4 $7 h6 {I'm including the
following alternatives (with !? symbols) to show that Black has a lot of
playable options and White is walking a tightrope. Who knows, maybe after one
of these alternatives Black will be able to press more than he can in my
recommendations. This shows that White isn't able to just memorize what to do
against my recommendation - his compensation is concrete and absolutely
requires concrete and exact play or else Black will consolidate. It's not the
sort of long-term compensation that White aims for when playing the Morra.} (

dissenting voice: in positions assessed at 0.00 by the engines, its evaluation
was often positive for itself. Putting that together with the score AlphaZero
was making in such positions, it made me wonder whether a new chapter had been
opened on 0.00 evaluations. (...) It would then be unsurprising if a
percentage of such narrow 0.00 paths were in fact better for the attacker, and
not holding for the defender.' - GM Matthew Sadler (Game Changer: AlphaZero's
Groundbreaking Chess Strategies and the Promise of AI)} Bxf3 {Black is playing
for an attack against the king with a draw in the pocket (via perpetual check)
and chances to play for more (even against many engine suggestions). White has
no way to play for more than a draw and is trying to defend. Therefore, I
claim a Black advantage. Is this advantage decisive or can it be consolidated
into a static advantage? This is the question that the following variations
attempt to answer. The analysis isn't completely comprehensive and there might
be improvements somewhere, but it goes to show that Black is pressing even if
White plays like a computer and that '0.00' doesn't always mean draw. White
fails to hold many of the following '0.00' positions. The onus is on White to
prove that he can equalize. After many false trails (and 20+ hrs of analyzing
with the computer), I believe that I found ways for White to defend against
Black's advantage and hold a draw, at least in the following 'recommendations'.
Black has many alternatives, of course, and White is playing for a draw in
every line. Many engine '0.00' lines can't be held by White, but some can. Not
every advantage is decisive with best play and I also don't think this one is,
but forces White to find some accurate defensive resources, and sometimes the
defensive resources that Stockfish declares '0.00' on aren't sufficient.} 22.

this can be for White.} (22. gxf3 $2 Qxf3 {followed by ...Nf4 wins for Black.

fully appropriate to quote GM John Shaw (Playing 1.e4: Caro-Kann, 1...e5 and
Minor Lines): "The computer evaluation 0.00 generally means something close to
the following: White has sacrificed material and no clear path to an advantage
is available, but he can force a draw if he wants to, for example with a
perpetual. it does not mean that nothing is going on in the position. (...)
You will find that not all 0.00 positions are defensible for the side with
extra material. You just need to get past the horizon."}) 22... Bxg2 {Lets not
forget that in the lines that follow, Black can obtain a draw by perpetual

Daniel Jones wrote a blog on chess.com claiming to counter the assertions that I made in my Chessable course ‘Mop up the Morra’. Daniel’s major claim was that Black does not have an advantage in my recommended mainline because in his view the engine’s preference for Black on move thirteen is too small to be categorized as an advantage. Daniel also claimed that 7...h6 is not a novelty as it was analyzed by Langrock before I published ‘Mop up the Morra.’ Daniel’s third claim was that my assertion that the Morra was ‘refuted’ and the claims in my advertisements were exaggerated. Here is my response. In my course and the US Chess article, I clearly defined novelty as in ‘not been played in FIDE master games’. According to this definition, 7...h6 would be categorized as a novelty even if Langrock’s book was released first. In any case, I discovered 7...h6 before I checked Langrock’s book, which I cited as a source before I published ‘Mop up the Morra’. My claim after 13...g6 is that Black is slightly better (=+). Refute can mean ‘prove to lead to a lost game’, but it can also mean ‘prove to be substandard or conceptually incorrect.’ I used definition two and this should be clear from my claim of a small Black advantage. It is well known that in advertising not everything is literal, so you have to use the context to interpret meaning. The aim of the Smith-Morra Gambit is to fight for the initiative and to obtain attacking compensation for the sacrificed pawn. In my recommended variation, White needs to play precisely to reach an endgame where he is defending and fighting for a draw. Conceptually, the Morra gambit is inaccurate because White’s dynamic compensation is gone and Black will be statically pressing. As for the chess-related portion of Daniel’s rebuttal, his post concludes that the engine assessment of -0.19 after 14.Nd6 is sufficient to claim that White’s position is either equal or close enough to being equal that White need not be concerned. However, not only is 14.Nd6 far too soon to be cutting off further exploration into the position (I analyzed 14.Nd6 significantly deeper in my course), but the comparison Daniel drew between this variation and a position after move three of the Spanish Game is not a fair one. In Jones’ quoted Morra position with 13...g6, the position is very settled, having reached a queenless middlegame with chances for only one side. In the Spanish position, all pieces and pawns remain on the board, countless options exist for both sides, and both sides have legitimate chances to play for a win. Due to the more settled and clarified nature of the line Daniel discussed from my repertoire, fewer branches exist, and the position better lends itself to deep and nuanced engine analysis than a position taken from move three of the Spanish Game.

{Note to reader, on 8/14/2019, by a coincidence, Logozar was online chess.com
the same time I was. I challenged him to an unrated game where I was white,
and played the Morra Gambit. He obviously used his line. We will be following
that game. (The ratings given were our chess.com blitz ratings at that time).}

to g6, then sooner or later h4! will force h5, and the bishop on e2 will be
indirectly attacking h5. Also, the bishop is probably better placed on e2 than
c4, as then it will block the c-file. This move has already been played a

{I don't think that this blitz game proves anything from the theoretical point
of view. Still, both of us can be in agreement about one thing: the Morra can
be a practical weapon for speed chess, even if it's unsound. Black can obtain
an advantage, but the resulting positions are often sharp and both sides are
more likely to blunder tactics if the position is sharper. In blitz, you don't
have much time to calculate the complications, so accidents can happen.} 1. e4

6.Bf4 is critical, especially not with 7.Be2. But Black behind in development
for the time being, so he should be careful.} Nge7 8. Bd6 Ng6 9. h4 Bxd6 {
As Tay said, 9...f6 and 9...h5 are playable alternatives. Black can
probably obtain an advantage using either of them, provided that he follows up
correctly.} 10. Qxd6 Qe7 11. Qg3 h5 $6 $15 (11... f6 $1 $17 {Black supports
the e5-square, preparing to meet h5 with ...Nge5. This is more difficult after
11...h5 (though Black should also be better there) as ...f6 would be met by
Qxg6. Where is White's compensation, exactly? Is it in his lead in
development? If he has no targets or effective pawn levers/sacrifices, he
won't be able to prevent Black from catching up. Is it in his space advantage?
Black can gain queenside space in the near future to compensate this. In short,
I don't think White has any compensation for the sacrificed pawn, provided
that Black plays carefully over the next few moves. With best play the
short-term dynamics will be neutralized, but if Black makes a mistake (for
example delaying development too long, making a weakness, or blundering a
tactic) then White might have an opporotunity to exploit his lead in
development. Stockfish is in agreement with me about White's lack of
compensation. "-0.88" - Stockfish 10 64, depth} 12. Rd1 {Given an exclaim by
Tay.} ({Stockfish initially thinks that} 12. O-O-O {is an alternative,
but eventually decides that White has no compensation for the sacrificed pawn
after} O-O (12... Nge5 {is also strong.}) (12... b5 {is also strong. White has
some practical chances after} 13. h5 Nge5 14. Nh4 {but Black can easily
neutralize this with} Na5 15. h6 g5 16. Bh5+ Kd8 $17 {it's not clear where
White's compensation lies or whos king is more exposed.})) 12... O-O (12... b5

kingside "attack". Black can develop his queenside before castling.}) 13. O-O
b5 14. h5 {Time to attack the knights!} Nge5 15. Nh4 {White is only playing
for practical chances, since he has no compensation for the sacrificed pawn.
Black is equally well developed (some of White's pieces aren't very active and
Black can easily activate his queenside with ...Bb7). There isn't even a need
for a sample line here as f4 threatens nothing (what after ...Nf7?) White has
no compensation for the sacrificed pawn. Stockfish agrees that White has no
compensation for the sacrificed pawn and declares "-1.15" at depth 38. Sample
line:} Kh8 16. f4 Nf7 $17 {Black will follow up with ...Bb7, ...Rfd8, and ...
Rac8. What will White to do justify his material deficit? f5 doesn't work due
to ...Nce5.}) 12. O-O-O {The rest of the game is not of great theoretical
interest because Black had an improvement on move 11, but I'd like to give
quick analysis anyways.} (12. Rd1 b5 (12... Qf6 13. Qc7 Nf4 14. O-O Nxe2+ 15.

with ...e5. Black can castle and give up the h5-pawn because he would still be
up material.}) (16... Qb4 $15 {Seems to give Black some. In analyzing this,
it's clear that White has some compensation, but I'm not sure if it's
sufficient.}) 17. Qf4 $1 {I agree with Tay's assessment of unclear
here, and it's possible that my claim of a small Black advantage after 12.Rd1
can be disputed. I don't think my claim after 11...f6 is seriously disputable
though, so it's not of theoretical interest to debate the comments after 11...

weakens the d7-pawn). Black intends to follow up with ...Qf4 and ...Nce5.
White can play Qd6 or Qc7, but this gives up the h4-pawn for questionable
compensation.}) 12... b5 13. e5 Qc5 $15 (13... Qb4 $17 {with ...Qg4 or ...Qf4.
