scored well for White in practice, although it is in the spirit of the
Richter-Rauzer. Black likely will not need to castle, anyways, and can start
the flank attack right away.11....gxf612.Bd3b4N13.Ne2Bd714.f5e515.Bc4?!...15.Kb1Perhaps White thought he was provoking Black's knight move,
but in practice it just gave Black a vital tempo to conduct the attack. This
prophylactic move is more logical.15....Nd416.Bd3Nxb3+17.axb3a518.Bc4Bc619.Bd5Rc820.c4a4?!21.Kc2...21.Qxb4!was playable, asaxb3(21...Rb8??22.Bxc6+)22.Qxb3is perfectly fine.21....axb3+22.Kxb3Bh623.Bxc6+Qxc624.Qd5Ke724...Rg825.Ng3Ke726.Qxc6Rxc627.Ra1Rc7⩲25.Qxc6Rxc626.Kxb4+−Rb6+27.Kc3Rg828.g3Rg4It looks like Black
has gained enough counterplay, and after White's next move the game is equal.
But one subtle finesse ensured a lasting plus:29.Kd3?...29.Rhe1!Kd7(29...Rxe4?30.Nf4!Rxe131.Nd5+Kd832.Rxe1Ra633.Nxf6+−)30.Ng1+−and where's Black's counterplay? The bad bishop and backwards d6-pawn
will be fatal.29....Rxb230.Nc3Kf831.Nd5Bg532.Nc3h533.Nb5h434.Kc3Re2?Another subtle point. The pawn is vulnerable on d6 now:34...Rf2!35.Rxd6(35.Nxd6Be3)Be336.gxh4Bc537.Rd8+Ke738.Rhd1Bd4+39.R1xd4exd4+40.Rxd4Rff435.gxh4...35.Nxd6!Be3??Is the
right idea, using the time White took to go after the d6-pawn to disconnect
White's pieces.36.Kd3!This is why the rook should not have been on e2.35....Be336.Kd3Rgg237.Rhe1Rxe138.Rxe1Bc539.Re2Rg440.Nc3Rxh441.Rg2Rh3+42.Kc2Bd443.Nd5Ra344.Kd1Ra1+45.Ke2Rc1?Black has been
holding serve, but overestimates his chances. The c4-pawn is weak, but once
Black takes it, there is no longer a serious weakness in White's camp to go
after.45...Ra346.Nxf6Ke747.Nd5+Kf848.f6Bc5and White has no way
to make progress, as:49.h4Rh3⩲is equal.46.Nxf6Rc2+47.Kf3Rc3+48.Kg4Rxc449.Kh5Ke750.Nd5+Kf851.Kh6Rc152.Kh7Rg1Now, White
misses a mating net.53.Rxg1?...53.Rc2!Bc554.Ra2Ke8There is no
other way out.55.Ra8+Kd756.h4Rh1and while Black picks up the h-pawn,
it doesn't matter:57.Kg7Rxh458.Kxf7Bf259.Rg8+−with a winning
position.53.Ra2+−also works.53....Bxg154.h3Bh255.Kh6Bf4+56.Kh5Bd257.f6Kg858.Ne7+Kf859.Kg4...59.Nf5was winning here, but White
finds it soon.Bb460.Kh6Bc561.h4+−59....Bc160.h4Bd260...Ke8!was the next-to-last chance, helping Black's king get back to the queenside
in time to meet White's king.61.h5Kd762.Kf5Ke863.Ng8Kf861.h5Bc162.Kf5...62.Nf5Ba363.Kg3Bc564.Nh6Bb465.Kf3Bd266.Ng4Bg567.Ke2Bf468.Kd3+−62....Bd2??Now it is too late.62...Ke8was the last chance.63.Kg4Bc164.Nf5Ba365.Kf3Bc166.Kg4Ba367.Kh4Bb468.Ne3Bd269.Ng4Bf470.Kh3Kg871.Kg2d571...Kh872.Kf3Kh7(72...Bd273.Ke2Bb474.Kd3Bc575.Kc4Kh776.Kd5Kg877.Kc6Kf878.Kd7Ba379.Ne3illustrates what happens if Black attempts to passively hold the
