Jan-17-10  cyclon: Without analyzing very much this time, I`d say more like intuitively (but after checking something, naturally), that; 16.Rxc6 Bxc6 ( -Rxc6 doesn`t seem to make much difference here) 17.Ne5 and where-ever Black Queen goes, White moves 18.Bxh7+ which has devastating effect in Blacks camp, f.e. -Kh8/f8 comes 19.Qh5 with pretty much mating-attack, which maybe by giving a Queen could only be prolonged. If instead 19. -Kxh7, then 20.Qh5+ Kg8 21.Qxf7+ K- 22.Re3 Bg5 23.Rh3+ Bh6 24.Rxh6+ mates next move.
Jan-17-10  cyclon: Okay, really fine play by White. In fact, these beginning moves (starting with 16.Rxc6) in this puzzle up to Blacks better defence; 19. -Bb4, were only PRELIMINARY. More difficult part was AHEAD, which was admirably conducted by White.
Jan-17-10  cyclon: <tallinn:> You`re right, 23.Nd7 is really a good move in that line. By the way, just for curiosity, what would "chips" says about the move 19. -Bd6 instead of 19. -Bb4, as in the game-line? And - in the game-line - what about (after 22.d5) 22. -Bxd5 instead of 22. -Bxe1? Just for curiosity.
Jan-17-10  David2009: Not even close. I looked at Rxc6 with the idea of 16.Rxc6 Bxc6 17. Ne5 Qd6? 18. Bxc6? Rxc6 19. Qf3 Rc7 20. Qxf7+ far too slow; so decided on 16. Re3 preparing it and with positional options. But Black has (for example) 16...Bf6 with a slow positional struggle in prospect. In fact after 17...Qd6? 18.Bxh7+! (a move I missed except in fantasies beginning 16. d5) is very strong

Like <dzechiel> I also looked at 16. d5 for a long time before deciding it gave less than nothing. So 16.Re3 was my final answer

Is the combination sound? Crafty thinks so i.e. defends with the game line until White's 27th (27. Bc5), when Crafty deviates with 27...Bb4!

Now White seems to have nothing better than perpetual check with 28.Qxf7+ Kb8 29. Nd7+ etc. Unless kibitzers can find something better?

Crafty link to position just before this diagram (White now plays Bc5): You are white, drag and drop the move you want to make. Happy analysing!

Jan-17-10  Skakalec: to david2009: I winn easily after: 27...Bb4 28. Bb4 a5 29. Bc5 Rcd8 30. Bb5 Rd1 31. Bf1 Rf1 32. Kf1 Qa6 33. Ke1 Rd8 34. Qe6 Kc7 35. Qe7 Kc8 36. Bd6 Rd6 37. Qd6
Jan-17-10  The Famous Chess Cat: I had Ba3 with the idea of decoying his dark-squared bishop away from its protection of the g5 square, allowing me to execute a classic bishop sacrifice.
Jan-17-10  WhiteRook48: not even close I wanted 16 Bxh7+ Kxh7 17 Qd3+ and 18 Re4??
Jan-17-10  Pawnage: My first whole week of correct solutions! :)

  agb2002: Material is even. Black would probably try the maneuver Nb4-d5 and Bf6 to block White's d-pawn and simplify the position with Bxe4 or Bxf3, if appropriate, to reduce the risk of attack against the king and achieve the better endgame.

The first idea that comes to mind is 16.d5 but after 16... exd5 the sacrifice 17.Bxh7+ doesn't seem to work because the knight can't move to g5. This suggests 16.Rxc6, to have the e5 square available to the knight:

A) 16... Bxc6 17.Ne5

A.1) 17... Qb7 18.Bxc6 (18.Bxh7+ Kxh7 19.Qh5+ Kg8 20.Qxf7+ Kh7 21.Re3 Bxg2) Rxc6 19.Qf3 Rec8 (19... Rcc8 20.Qxb7; 19... Bf8 20.Qxc6; 19... Rc7 20.Qxf7+ Kh8 21.Qxe8+) 20.Qxf7+ Kh8 21.Nxc6 Qxc6 22.d5 + -, threatening 22.Qxg7#, 22.dxc6 and 22.Qxe7.

A.2) 17... Qd6 18.Bxc6 Rxc6 19.Qf3 Rcc8 (19... Rec8 20.Qxf7+ Kh8 21.Nxc6 Qxc6 22.d5) 20.d5 (threatens 21.Ng6+ hxg6 22.Qxg7#) Bf8 21.Qxe8 Rxe8 (21... Qxe5 22.Qxf8+) 22.Nf7+ Kg8 23.Nxd6 Bxd6 24.dxe6 + - [2P].

B) 16... Rxc6 17.Ne5

B.1) 17... Qc7 18.Qf3

B.1.a) 18... Rec8 19.Qxf7+ Kh7 20.Nxc6 Bxc6 21.Bxc6 Qxc6 22.d5 + -.

B.1.b) 18... f6 19.Bxc6 Bxc6 20.Nxc6 Bf8 21.d5 + -.

B.2) 17... Qd6 18.Qf3 seems to transpose to previous lines.

It's 1:00 am, time to check and go to bed.

Jan-17-10  gofer: It took a second to see that c6 and f7 are the key focus of the attack, but Ne5 is the key move. Ne5 attacks Qd7, Pf7 and which ever piece is on c6. This is immediately followed up by Qf3 further attacking c6 and Pf7. So how to now make the attack into mate? Well obviously, once we have managed to play Qxf7+ Kh8 we just need to open up the a1-h8 diagonal with d5!

16 Rxc6

16 ... Rxc6
17 Ne5 Qc7 (Qd6 offers Nxf7+ once Kh8 has been forced by Qxf7+) 18 Qf3 Rc8 (Bf6 19 Nxc6 winning a piece and Rf8 Bxc6 winning a piece)

19 Qxf7+ Kh8
20 Bxc6 Bxc6
21 Nxc6 Bf6
21 Qxc7 Rxc7
22 Rxe6 winning

16 ... Bxc6
17 Ne5 Qb7 (Qd6 offers Nxf7+ once Kh8 has been forced by Qxf7+ and Qc7 allows Bxc6)

18 Qf3 Bxe4
19 Qxf7+ Kh8
20 d5 Rg8 (Bh6 21 Qxb7 winning Qxd5/Bxd5 21 Ng6+ hxg6 22 Qxg7#)

21 Qxe6 Rf8/Rcf8 (Bg6 22 Nxg6+ hxg6 23 Qh3+ mating)
22 Nf7+ Rxf7
23 Qxf7 Rg8
24 d6 winning

Time to check...

Jan-17-10  gofer: Okay, what's so wrong with 18 Qf3?
Jan-17-10  tacticalmonster: 1) white isolated d4 pawn suggests dynamic play. This translates to either kingside or queenside offense. In this case, it is the kingside since white has two bishops pointing at (b2-g7) and (e4-h7) diagonal. 2) black kingside lacks defending pieces. There are no Rf8 and Nf6. Be7 gets in the way of the queen defending f7. e6 pawn really hammer in the queen and e8 rook. Black has two weaks squares f7 and h7. g7 is potentially weak.

3) White queen belong either g4 or h5 and the knight belong to e5 outpost. Rook needs to lift itself to either g3 or h3 via c3 or e3. A d5 pawn push may be in order to open up the b2-g7 diagonal.

candidate: Rxc6

a) 1 Rxc6 Bxc6 2 Ne5 Qb7 3 Bxh7+ Kxh7 4 Qh5+ Kg8 5 Qxf7+ Kh7 ( 5 Kh8? 6

Jan-17-10  zanshin: <gofer: Okay, what's so wrong with 18 Qf3?>

Apparently, it loses to <18...Bb4> protecting f7 while attacking the Rook - but I have not checked the line.

Jan-17-10  LimSJ: i only saw the Bh7 sac-theme but can't go through more than after 17.Ne5. i appreciate the tactics arising from the possibilities of 18...Kh7 and 20...Be1 that are worth looking into from an unrated player's point of view and over the board on my lunch break (as i don't have a chess software here in the office). amazing and cheers to Portisch! back to work.
Jan-17-10  VargPOD: Sunday.

Got nowhere on this one. Did not try very long though. Weekend puzzles are just over my head.

Total 4/7 (7,5/14). Still above the 50% mark, barely.

Jan-17-10  patzer2: For today's Sunday puzzle solution, the deflection sham sacrifice 16. Rxc6!! and the follow-up 16...Bxe6 17. Ne5 (clearance and deflection) prepares a decisive demolition of the weakened castled position after 17...Qb7 18. Bxh7+! .

The game takes on somewhat the characteristics of a pursuit combination after 21. Qh6+ Ke7. The final position relies on a decisive pawn promotion after 30...Rxd7 31. cxd7+ Kc7 32. dxe8(Q) .

Jan-17-10  RandomVisitor: After 15.Be4, top 5 moves, final look. We see that 15...Qd7?? allows a critical tempo-gaining move 17.Ne5, which does not work with these alternative queen placements:

I saw the possibility of ... Bb4 or ... Ba3 when I was trying to make 16.d5 work but forgot completely when considering Qf3. Conclusion: leave deep analysis for a better occasion if you are about to snore.

Jan-18-10  cyclon: <gofer:18 Qf3 Bxe4 [ -Bb4 and WHITE is in trouble] 19 Qxf7+ Kh8

Simply 24. -Bxd6 and BLACK is winning.

Now White seems to have nothing better than perpetual check with 28.Qxf7+ Kb8 29. Nd7+ etc. Unless kibitzers can find something better?> INSTEAD of 29.Nd7+ etc.? I`d play 29.c7+ Rxc7 ( -Kb7? 30.Be4+ wins Queen) 30.Qxe8+ Rc8 (forced) 31.Qxb5+ Kc7 32.Qxb4 winning EASILY.

  LIFE Master AJ: 20...g6?!; (maybe - '?') was obviously inferior.

What a combo ... as for the guy who said, "I didn't know that Portisch was this good." ... ... ... did you know that Portisch was (at one time) easily in the "Top Ten" players in the world? [

Premium Chessgames Member
  perfidious: This is the finest game I have seen by Portisch. A work of art!

Lajos Portisch had everything going for him, except a psychological instability which tended to show at critical moments. Few in history, however, can equal his sustained level as a top-class player, and almost no-one who has not held the title of World Champion.

Premium Chessgames Member
  ToTheDeath: Agreed, this is a remarkable game, with similarities to his famous loss to Kasparov in 1983. Apparently Lajos was taking notes in that encounter!
Feb-11-17  Moszkowski012273: 18.Qh5... is another way to win!
