A Sacrificial Lamb by IM Igor Khmelnitsky
STOP - Lecture begins below.
Chess books and software tools dedicated to the subject of Tactics always
have a section devoted to the advanced passed pawn. In my
Chess Exam Tactics, one of the six Motives I am rating the readers
on is the “Advanced Pass Pawn”.
Eliminating
and deflecting the defender(s) are the most popular ideas. For
example, in the diagram on the right: 1.Rxb6 (defense elimination) and
1.Rxd5 (deflection of the defender). Rarely,
you will see examples where the coveted passed pawn is actually given up
for some material or even positional gains: 1.Pc8Q Nxc8 2.Rxd5
A recent
encounter at the very top level triggered my decision to discuss the
situation where the "golden pawn or pawns" that reached the 7th (2nd) rank
are sacrificed. The examples you will see in this article are from my
lessons.
First, let’s
take a look at the game that prompted this article:
#1 Kramnik,V - Leko,P, Black was hoping to give up his two
pieces for the dangerous white pawns and one of the white pieces, then
trying his chances on the K-side. For example, 1.Rb8? Nxa7 2.Bxa7
Rxc7+ and Black is better. Rather then trying to get the pawns
through, Kramnik gave them away, but won the N and trapped the Black K
in the mating net: 1.Pa8Q Rxa8 2.Pc8Q+ Kxc8 3.Kxc6
1:0 (2 points) Theme
- Deflection.
After 1...Pf7-f5
#2 Trolldalen,M - Bernstein,D EU-ch U20, Groningen, 1976 If not for the Pe7, White would have a checkmate in one move, hence
the pawn is sacrificed. Also, White must use under-promotion, as
the direct 1.Pe8Q? is not sufficient due to 1…Nd5+ Instead, White won after 1.Pe8N+
Rxe8 (1…Kd5 2.Rd7+ Ke4 3.Nd6+ and 4.Nxc8) 2.Rd7# (2 points) Theme – Clearance, Under-promotion. After 1...Kd5-d6
#3 Ragozin,V - Boleslavsky,I, URS-ch14 Moscow, 1945 Black’s last move 1…Kg8-f7
was a major error. White punished him with 2.Pe8Q+ 1:0
(2...Kxe8 3.Ba4). Instead, Black should have played 1…Rb5-b8,
eventually winning the Pe7 as White can’t play 2.Ba4 due to Back rank
checkmate after 2...Rb1+. (1 point)
Theme – Decoy into a Pin. After 1...Kg8-f7
#4 Dahm,J - Essing,A The Queen is usually the worst blocker as it is vulnerable to attack
by any piece. In this example, White played 1.Pd8Q+ Qxd8 2.Pe7+
winning. (1 point)
Theme – Deflection, Decoy, Discovered attack. White to Move
#5 Hebden,M - Eslon,J Black is trying to hold-on by building some sort of a fortress,
thanks to the Bishops of opposite color. But White finds the way
to break through with his R: 1.PeQ+ Bxe8 2.Re7+ Kf8 3.Pd7 Bxd7 (3…Kxe7 4.Pd8Q+)
4.Rxd7 winning. (2 points)
Theme – Clearance. After 1...Ra8-a6
#6 Doroshkievich,V - Balitinov,
USSR,1980 The Black K is trying to help in stopping the
dangerous passed P, so White shifts his attention from promoting the P
to attacking the K. 1.Pe8Q+ Ne8 2.Nf5.
Black resigned as he can’t stop or prepare defense against 3.Qe7+. (2
points)
Theme – Clearance After 1...Ra8-a6
#7 Training Position This is one of the basic endgames that must be
memorized. Black uses h8 as a hiding squared since White K can’t
come closer due to a stalemate. 1.Ke6 Kh8 etc…. Instead, White gives up the Ph7 eliminating the
stalemate and transposing into the won K+P vs. K endgame. 1.Ph8Q+ Kxh8 2.Kf6 Kg8 3.Pg7 Kh7
3.Kf7 etc… (2 points) Theme – Avoiding Stalemate And,
since we have discussed avoiding a Draw, the next position is an example
where the passed pawn is sacrificed to force a draw! White to Move
#8 Hamming,A - Wacker,M, Facing some serious threats, Black found a neat
escape thanks to a stalemate. He actually has two distinct ways: 1…Ra3 2.Rxa3 Pa1Q+ 3.Rxa1=
or 1…Pa1Q+ 2.Rxa1 Ra3 3.Rg1 Rg3
etc… (2 points)
Theme – Stalemate via a Self-Elimination. After 1.Kg6-f6
#9 Lanzani,M - Sulava,N,
Montecatini Terme op, 1994 The Knight is one of the worst pieces to be near the passed pawn,
specifically due to the situation that have arisen in this game after
1.Pf8Q Nxf8 2.Pe7 (only
something like Ra8 or Kf7 can stop the pawn as both e8 and f8 need to be
covered). However, you only get partial credit (2 points) if you stopped here.
Black has a strong counter play thanks to the advanced c-P and ability
of the N to cover his K from the checks. After 2…Ne6 3.Pe8Q Nc5+ 4.Ke3 Pc2 5.Qb5+ Nb3,
Draw was agreed in view of 6.Qe2 Kb1 7.Qd3 Kb2,
etc. (4
points) Theme
– Decoy and Deflection. After 1.Kg6-f6
=================================================================== Summary: whenever you see the far advanced pawn, remember that in addition to an objective of getting the pawn promoted, you could use it a sacrificial lamb to accomplish something critical.
