  al wazir: I got 20...Re2 21. Qxd7 Kb7 22. Bxe2 Rxe2 23. Rd2, but I probably wouldn't have been able to win the endgame.
Apr-19-14  john barleycorn: As far as I know Karpov never played 9.... g5 in this line when facing Kasparov.

There is one rapid game where Karpov played it - and it is vs. Macieja:

Macieja vs Karpov, 2003

Apr-19-14  john barleycorn: In fact, 9....g5 is an idea introduced by Anand in his 1995 match with Kasparov.

When analysing an old opening I find it helpful to consult old books and articles.

Apr-19-14  morfishine: An excellent exercise focusing on imagining an other's imagination
Apr-19-14  mistreaver: Saturday. Black to play. Very Difficult. 20?
After long pause from writing this notepads i have decided to return since my chess has kinda started to deteoriate. Black's knight is kinda living on the edge, but there is some motive for sure with the c3 square which is under the mask of the black rook and queen. At first i was looking to put the rook on e1, but then i thought of much better move (at least i hope it's better): 20 ... Re2!!
If this works, it will be brilliant.
White doesn't have much choice
A) 21 Bxe2 Nc3+
and now:
A1)
22 Qxc3 Qxc3 leaves black with queen for rook and a knight, and a much better coordination. A2)
22 Kc2 Rxe2
23 Qxe2 Nxe2
and here black has queen for 2 rooks, but white's pieces are again uncoordinated and his king is exposed. A3)
21 Kc1 Rxe2
22 Qplays Na2+ and
23 ... Qb2 mate
B) There is actually one other defence try:
21 Qd4 the only move to prevent mate on b2
21 ... Nc3+
and here the simple Qxd2 could be enough?
22 Qxd2
Time to stop and see.
---
Oh, i wasn't even looking at the fact that white can capture on d7, in that case my Rybka says that white has the equal game for a long time, until he goes wrong in the endgame.
Apr-19-14  Cheapo by the Dozen: I'm starting out stumped. I'd like the answer to start:

20 ... Rd5
21 cxd5 Nc3+
22 Kc2/Kc1 Nxd1

Either capture of the knight is now awkward, with fun lines like:

23 Kxd1 Qa1+
24 Qc1 Re1+

But I see at least two problems with this idea:

A. White can interpolate Bxa6+
B. If White shuttles his king between c1 and c2, it's hard to see how Black gets more than a perpetual check.

20 ... Re2 instead gives Black an excellent chance of doubling queen & rook on the 7th rank. But except for an out-of-play bishop, those will be the only two pieces he has left, which looks insufficient to win.

Apr-19-14  patzer2: What a sharply played game! Always thought of the Scotch as mostly an open tactical game, but this contest shows it can be highly technical and positional as well.

As for today's Saturday puzzle, looks to me as though 20...Re2! is pretty much forced as more passive tries simply result in the loss of the Knight on a2 with a decisive material advantage for White.

In any event today's puzzle is far from a forced win for Black. For example White could have played 27. Qd3! when Black has nothing better than a draw by perpetual after 27...Nd4+ 28. Kc3 Ne2+ 29. Kc2 Nd4+ 30. Kc3 Ne2+ 31. Kc2=.

Apr-19-14  patzer2: After 27. Nf5?! Qe4+! to , it starts to turn in Black's favor.

The remainder of the game is an excellent technical display of the superiority of two minor pieces versus the lone Rook.

Apr-19-14  JohnBoy: Immediate thought - 20...Re2 is devastating.

BUT - as usual - there is far more to the story. AJs analysis above shows me that things are not so simple and my considerations are way too superficial. Nice work.

  Penguincw: I had ideas of 20...Re2 21.Bxe2 Rxe2 22.Qxe2 Nc3+ 23.Kc2 Nxe2 which leaves black up a ♔♕♗♙ for a ♔♖♖, although it isn't forced.
Apr-19-14  Patriot: Black is up a pawn. White threatens 21.Qxa2 or 21.Qxd7+.

20...Re2 is my first candidate.

21.Bxe2 Rxe2 22.Qxe2 Nc3+

21.Bxe2 Rxe2 22.Qxd7+ Kb7 23.Rd2 Nc3+ 24.Kc2 may be a problem for black.

21.Bxe2 Nc3+ looks really good, with 22...Rxe2 coming next.

21.Qxd7+ Kb7 22.Rd2 Re1+ 23.Rd1 Rxd1+ 24.Qxd1 Nc3+

Apr-19-14  Patriot: I missed the subtle variation played in the game, which transposes to my second 21.Bxe2 line on move 23. I'm also wondering why I missed 23...Qxf2.

At move 33 White looks hardly worse...but he is.

  agb2002: Black is one pawn ahead.

White threatens 21.K(Q)xa2 and 21.Qxd7+.

The first threat and the position of White's heavy pieces suggests 20... Rxe2, protecting momentarily the knight and unblocking the a1-h8 diagonal:

A) 21.Bxe2 Nc3+

A.1) 22.Ka1 Nxd1+ 23.Kb1(a2) Rxe2 24.Rxd1 (24.Qxe2 Nc3+ and 25... Nxe2 - + [Q+B+P vs R]) 24... Rxd2 25.Rxd2 Qc3 - + [Q+B+P vs R+N].

A.2) 22.Kb2(c2) Rxe2 - + [Q+B+P vs 2R].

A.3) 22.Kc1 Rxe2 23.Qxd7+ Kb7 24.Rd2 (due to 24... Na2+ 25.Kb1 Qb2#) 24... Nd5 25.Rxe2 (25.cxd5 Qa1+ 26.Kc2 Qa2+ and mate in two) 25... Qa1+ and Black has perpetual at least.

B) 21.Qxd7+ Kb7

B.1) 22.Bxe2 Rxe2 23.Rd2 Qxf2, unclear.

B.2) 22.Qd4 Nc3+ 23.Kc1 (23.Ka1 Ra2#) 23... Rd8 wins (24.Qxf6 Rxd8#).

Apr-19-14  Jamboree: White loses the game AFTER the so-called combination with 30. Kc3??

Instead, the more active 30. Kd3! seems to ensure the draw:

30. Kd3! Nxf5 31. Ke4 Nd6+ 32. Kf4 f5 33. h3! gxh3 34. Rh1 Kb6 35. Rxh3 Bc8 36. Rxh7 and white has enough activity to keep a solid grip on the position, whereas black is still for the moment kind of tied up in knots.

In that final position the c7 pawn is terribly weak; the bishop has almost no mobility; and none of black's pawns are connected. White will be able to play either Re7 or Ke5 to tie up black even further. There are even lines where if black in not careful white can sac the rook for the bishop, forcing the N to recapture, and then win the f pawn and escort the g pawn to the last rank, winning back the knight and forcing a draw (though that is far in the future).

If black tries to get sneaky and play 33. ... h5, then he risks LOSING because the rook will be able to penetrate before any defenders and win the black h-pawn, creating a dangerous passed pawn.

This "winning combination" is not so cut-and-dried.

Apr-19-14  Marmot PFL: Worked the game line out to move 23, and decided that 24 Rxe2 Qxe2 25 Qd4 Nc3+ 26 Qxc3 Qe4+ 27 Kb2 Qxh1 28 Qb4+ looked like a draw...
Apr-19-14  Cheapo by the Dozen: It looks like White just hung a piece on Move 27. Was that really necessary, or would passive play have gotten him a draw?

Good post, honest, too. (Thanks.)

Apr-20-14  LIFE Master AJ: < <<<>>> <Cheapo> It looks like White just hung a piece on Move 27. Was that really necessary, or would passive play have gotten him a draw? >

My analysis pretty much covers all of that.

Apr-20-14  LIFE Master AJ: The engines show that White made several mistakes ... and 5-6 inaccurate moves.

With best play, White could have forced a draw. I would bet on two things:

A.) Macieja saw that he could force a draw ... probably a couple of times ...

B.) That he played on in an attempt to win.

Apr-20-14  john barleycorn: As usual <chrisowen> gives a detailed analysis. Take your time to look into it, it is really worth it. no kidding.
