Mar-08-04		perplex: Some notes: 1)Could 9 Qc2 be prevented by Black? It was a very good reinforcement to center by White, preparing e4. 2)After 11 e4, White enjoys a space advantage. 3)b3 prevents a possible ...Ba6 threat. 4)Establishing a strong bind, Botvinnik starts to crack Black's base. 5)...Ne8 is an attempt to play ...f5 and make a attack. 6)With Qd2, White pours his power on d file. Target is d7-Knight. That's why Bot plays Bh3. 7)...f6 is an reinforecement on e5. 8)...Qg7 and Be6+!, following d5. Nice play, Bot!

Dec-11-05		fred lennox: 22.Rd2 is a finesse move, showing Botvinnik's authorative and astute playing. 22.Rc1 ignores the threat of...Nc5-d3. So now 22....Nc5 23.b4. 22.b4 does the trick too and is simple. For me, the text move is more delicate and powerful. Even has the advantage of being taken by the queen without check. In the end, b4 looks as good. 22...f5 misjudges the position.

Oct-16-10		sevenseaman: 30...Qxd2. It was difficult to imagine Grigoriev would go for the White R with his own under fire. May be this game is here by default!

Oct-16-10		keypusher: <sevenseaman: 30...Qxd2. It was difficult to imagine Grigoriev would go for the White R with his own under fire.> You have a better move for Black than ...Qxd2?

Jul-01-11		Moses2792796: Botvinnik gives the losing move as 22...f5? His annotations suggest that if black plays 22...a5 and 23...Nc5 he is equal. Also regarding the comment on 30...Qxd2, every variation after whites 30th move leads to a quick loss for black, take some time to analyse before you comment.

Jul-31-13		TheFocus: From the Leningrad - Moscow Team Match.

Mar-30-16		Penguincw: A Wednesday puzzle (hopefully it's not as tricky as yesterday). And, I actually made it pretty far. I got 28.Rxe5 dxe5 29.d6. That's as far as I calculated. However, OTB, I think I would've gotten the whole puzzle. 29...Qd8 30.dxc7 Qxd2 31.Qxf8+ Ng8 32.c8=Q. Yeah, black has 32...Qd1+ 33.Kg2 Qd5+, but after 34.Kh3, I don't see a good way for black to continue. Note that white also has a mate threat on f6.

Mar-30-16		catlover: <Penguincw> Same here. I did not observe the powerful effect of the Bishop on f5 bearing down on c8. I thought that if 30...Qg7, 31. QxQ+ KxQ, and I thought "And now what?" I missed that Black was going to have to lose a rook because of the threat of that pawn on c7 queening.

Mar-30-16		patfoley: There is some clever stuff if 28 ... Qxe5, 29Qxf8ch Ng1 30 Qf7 Nf6 31 gxf4! Qxf5 32 Qf8 ch again

Mar-30-16		al wazir: 28. Rxe5 Qxe5 29. Qxf8+ Ng8 30. Rc2 Ne8 31. Rc8 Nf6. White is up an exchange and a ♙. I suppose that's winning, but if I were black I'd play on a few more moves. In this line 30...Qe7 might also be playable, but it looks as if it loses at least one ♙.

Mar-30-16		stacase: Burn a Rook in order to fork Black's Queen and Knight plus get a very dangerous passed Pawn. Looks like plan to me.

Mar-30-16		chessamateur: Got it.... Mon. Tues. Wed... I probably won't do so well by Friday though.

Mar-30-16		agb2002: White has a rook and a bishop for two knights. Black threatens 28... Ncxd5. The black queen protects the rook and the black d-pawn stops d6, forking queen and knight. This leads to consider 28.Rxe5: A) 28... dxe5 29.d6 A.1) 29... Qd8 30.dxc7 A.1.a) 31... Qxd2 32.Qxf8+ Ng8 33.c8=Q wins since there's no perpetual. A.1.b) 31... Qxc7 32.Qxf8+ Ng8 33.Rd8 wins. A.1.c) 31... Qe8 32.Qxf8+ Qxf8 33.Rd8 wins. A.2) 29... Qe8 30.dxc7 followed by c8=Q, winning. A.3) 29... Qg7 30.Qxg7+ Kxg7 31.dxc7 followed by c8=Q, winning. A.4) 29... Qf7 30.Qxf8+ Qxf8 31.dxc7 followed by c8=Q, winning. B) 28... Qxe5 29.Qxf8+ Ng8 30.Qf7 B.1) 30... Qe7 31.Qxe7 Nxe7 32.Be4 fxg3 33.hxg3 + - [R+B+P vs 2N]. B.2) 30... Qg7 31.Qxg7+ is similar to B.1. C) 28... Ng8 29.Rxe7 Nxh6 30.Rxh7+ Kg8 31.Rxh6 Rxf5 32.Rxd6 + - [R+3P vs N]. D) 28... Qd8 29.Re4 wins at least a pawn with a winning position. For example, 29... fxg3 (29... Nxe4 30.Qxh7#; 29... Ncxd5 30.Rxd5) 30.hxg3 Rf7 31.Rc4 followed by Rdc2. E) 28... Qf7 29.Be6 with a similar conclusion as D. For example, 29... Ng8 30.Qh4 Qg7 31.Rf5 + - [R+B+P vs 2N]. F) 28... Qg7 29.Qxg7+ Kxg7 30.Re7+ Rf7 31.Rxf7+ with a won ending.

Mar-30-16		not not: black rook is hanging (queen defending it) so Rxe5 wins a pawn at least; if black recapture with pawn the other white pawn starts marching with gain of tempo (queen and knight fork); that's as far as I saw

Mar-30-16		not not: but being exchange up, even without combination, white should win anyway playing anything; so any move wins, quicker or longer

Mar-30-16		diagonalley: good wednesday puzzle

Mar-30-16		jith1207: Perfectly solved all the variations. Though I missed to study more in depth on yesterday puzzle. This one though screamed out loud at me because of the position of rooks, potential passing pawn, bishop supporting the promotion square and the Queen, along with all weakly linked black pieces. Though I found the solution instantly, had to work through the lines to be sure as to have an escape route for white king before the eventual mate on black king.

Mar-30-16		morfishine: Nice combination. I had <28.Rxe5> and was good through 28...dxe5 29.d6 Qd8 30.dxc7 and figured couldn't play 30...Qxd2 due to 31.Qxf8 mate, but its not mate due to 31...Ng8, which doesn't matter due to 32.c8=Q

Mar-30-16		not not: my simple plan would be a pawn sacrifice with Bishop going to e6, then doubling rook on open c-file and invade into seventh rank (like german tanks once they got an open road in maginot line of french bunkers-pawns) what can black do once both rook end up on seventh rank via c-file?

Mar-30-16		mikealando: wow. some amazing chess was being played in 1927.

Mar-30-16		saturn2: White is already up an exchange. 28 Rxe5 wins since after ..dxRe5 29 d6 the black Queen is overloaded. She cannot defend the Rf8 and win back material at the same time.

Mar-30-16		alphee: Among other options the only attractive one was 28. ♖e5 de5 29. d6 ♕d8 30. dc7 but I never thought of … ♕d2 (whose logic escapes me), hence I was stuck. Nevertheless, it's probably what I would have played.

Mar-30-16		gofer: The first move is fine, but I don't think black should accept the sacrifice... <28 Rxe5 ...> 28 ... Qxe5 29 Qxf8+ Ng8 30 Qf7 28 ... dxe5 29 d6 Qg7 (Qd8 30 Qxf8+ Qxf8 31 dxc7 ) 30 Qxg7+ Kxg7 31 dxc7 So we should get to here... <28 ... Qg7> <29 Qxg7+ Kxg7> <30 Re7+ Rf7> <31 Rxf7+ Kxf7> click for larger view and then perhaps to here... 32 Be6+ Nxe6 33 dxe6 Kxe6 34 f3 fxg3 35 hxg3 ... click for larger view Hmmm, is this a "won" endgame? <Probably>. ~~~ Was it really necessary to walk into the nightmare by accepting the sacrifice?

Mar-30-16		JimmyRockHound: The only good move I could see was Rxe5. I didn't bother calculating further because I'm a total patzer.

Mar-30-16		dfcx: White is already ahead by an exchange. The black queen is overloaded with protecting the rook and back rank. 28.Rxe5 leaves black with awkward choices A. 28...Qxe5 29.Qxf8+ Ng8 30.Rc2 wins B. 28...dxe5 29.d6 Qf7/d8/e8 30.dxc7 with threat of Rd8 or Qxf8/c8=Q to follow
