  plang: Both players effectively avoided mainline theory ending up in an offbeat Kings Indian. In game 6 of their 8 game 1994 match in Monaco Ljubojevic had played 5 Qd2 against Piket and Black had gone on to win; 5 Nf3 was new. 6 Qd3!? with the idea of queenside castling was an unorthodox idea; besides the normal looking moves 6 e3 and 6 e4 an alternative idea is 6 Nd2!? with the idea of showing that the bishop on g4 is misplaced. Piket thought that he could have improved with 8..Nb4 9 Qd2..Bxf3 10 gxf..c5 with an unclear position. Timman thought he would have had an advantage had he played 13 Kb1..e5 14 Be3..exd 15 Bxd4..Bxd4 16 Rxd4..Qe5 17 e3. After 16..f5 Black was already better; taking the pawn with 17 Rxd6..Ne5 18 Rxd8+..Rxd8 19 Qf4..Nc5 20 Qf3..Na4 would have given Black great attacking chances. Timman's choice of 17 Bg2?! weakened d3 and c4; 17 e3 would have been better. Piket's concluding attack was pretty.

Both players played this game very creatively from move 3 onward.

Sep-06-22  Brenin: 27 ... Nxb3+ 28 Kb1 (28 axb3 Qa3+ 29 Kb1 Qb2 mate) Nd4+ 29 Kc1 (29 Ka1 Qb2 mate) Qb2+ 30 Kd1 Qa1+ 31 Nb1 Qxb1 mate. A pretty finish.
Sep-06-22  mayankk06: I had 27 ... Nxb3 28 Kb1 Nbd2+ 29 Kc1 Qb2+ 30 Qd1 Qa1+ 31 Nb1 Qxb1#
Sep-06-22  King.Arthur.Brazil: The King's answer is: 27...♘xb3+ 28. ♔b1 ♘c5+ 29. ♔c1 ♕b2+ 30. ♔d1 ♘xd3 check-mate next.
Sep-06-22  King.Arthur.Brazil: Oops: 29.♕a1 ♘b1 30.♕b1# will spend 1 move less. A little fault. <Brenin/maya> are right.

  al wazir: 27...Nxb3+ 28. Kb1 (28. axb3 Qa3+ 29. Kb1 Qb2#) Na3+ 29. Kb2 Nd4+ 30. Kc1 Qb1+ 31. Kd2 Nc4#
Sep-06-22  jrredfield: I saw 27 ... Nxb3+ right away. It's a mate in 5. However, 27 ... Rhe8, 27 ... Rhf8 and 27 ... Ne5 are all strong moves. Like yesterday, there are so many winning lines that I wonder how White got into such a vulnerable position. 18. Qe3 would have been better for White. By his 20th move or so, White was already in big trouble.

  agb2002: Black has a knight and a pawn for a bishop.

The pawn on a2 avoids a killing check from a3. Hence, 27... Nxb3+:

A) 28.axb3 Qa3+ and 29... Qb2#.

B) 28.Kb1 Nd4+ 29.Kc1 (29.Ka1 Qb2# or 29... Nc2#) 29... Qb2+ 30.Kd1 Qa1+ 31.Nb1 Qxb1#.

  boringplayer: I appreciate all the daily posters and their analysis. Helpful stuff for me.
Sep-06-22  takebackok: Once you see Nxb3 the next moves play without much thought. Also, anyone seen MC is he ok?!

  Teyss: <mayankk06> <King.Arthur.Brazil> 30...Qa1+ 31.Kc2 still wins but no mate. That's why 28...Nd4+ as per <Brenin> and <agb2002> has to be on that square, it controls c2.

<al wazir> 30...Qb1+ 31.Nxb1.

Sep-06-22  saturn2: Queen plus knight(s). A deadly combo.
Sep-06-22  saturn2: <King.Arthur.Brazil: The King's answer is: 27...♘xb3+ 28. ♔b1 ♘c5+ 29. ♔c1 ♕b2+ 30. ♔d1 ♘xd3 check-mate next >

<Oops: 29.♕a1 ♘b1 30.♕b1# will spend 1 move less. A little fault.>

The difference makes your move 28...Nc5 instead of the better 28...Nd4

3 pieces bearing down and one is a Queen - LOL

  perfidious: <boringplayer: I appreciate all the daily posters and their analysis. Helpful stuff for me.>

Same for this heah life 1200 player.

<mel: White is so busted....>

Something of a departure from the standard theme of 'I got this thang in a nannysecond'....

Sep-06-22  TheaN: <Brenin: 27 ... Nxb3+ 28 Kb1 (28 axb3 Qa3+ 29 Kb1 Qb2 mate) Nd4+ 29 Kc1 (29 Ka1 Qb2 mate) Qb2+ 30 Kd1 Qa1+ 31 Nb1 Qxb1 mate. A pretty finish.>

This. Coffee time :>.

Small addition to this though, I actually thought there'd be a faster mate in the Kb1 line, but that's where the weaknesses of knights show. They're good in taking a lot of squares, but as a consequence give them up quickly as well:

The knights are taking in tandem a1 and c1 (Nb3) and b2 (Nc4). Black has Na3+, which makes the c-knight take b1 and c2, but then we're missing b2: the queen can't really join unless Nb3 moves, but then we give up a1 and c1.

Tl;dr: 28....Nd4+ <is> in fact fastest, as it restores the knight tandem taking the second rank (Nc4 b2 and d2 and Nd4 c2 and e2), and after 29.Kc1 Qb2+ #2 the back rank is hers.

  al wazir: <Teyss: 30...Qb1+ 31.Nxb1.>? Oops.

After 30...Qb2 31. Qg5 Qa1+ 32. Qc1 Nb2+, black wins eventually, but it's ugly.

Sep-06-22  Hercdon: Easier than most Mondays
Sep-06-22  TheaN: <al wazir: <Teyss: 30...Qb1+ 31.Nxb1.>? Oops.

After 30...Qb2 31. Qg5 Qa1+ 32. Qc1 Nb2+, black wins eventually, but it's ugly.>

After 30....Qb2+? 31.Kxb2 +- and I think you lost track entirely... instead if you do go this route 30....Nxe2+!, in case 31.Nxe2 then 31....Qb1+ 32.Kd2 Nc4+ 33.Kc3 Qb2+ 34.Kxc4 b5# which is kind of pretty. Instead, 31.Kd1 Nxc3+ #10 and Black wins a piece with the White king wide open.

Sep-06-22  johnnydeep: Sigh - I though surely it must be a pretty double knight attack via 27...Nc2+ 28. Kb1 N4a3+, but that leads nowhere fast.

  Check It Out: A pretty mate:
27...Nxb3+ 28. Kb1 Qa3 29. Qxd8+ Rxd8 30. Na4 Qb2+ 31. Nxb2 Na3#

  Teyss: <Check It Out> 28...Qa3! is a pretty alternative, didn't consider it. If 29.Rd2, Qb2+ all the same. If 29.Kc2, Qb2+ 30.Kd1 Qc1# This line is as good as the one we saw since it mates in the same number of moves (Qxd8+ included).

Says how bad White's position was. You were right to check it out.
