| Jul-07-12 | | gofer: Well it's "under-promotion" so I am looking at <46 f8=N+> and I work through
the possible variations and then come back to looking at threats, finally after
a minute or two I notice I am in check! "Way to go Dumb-Ass!" Okay, but the
under-promotion is still my main threat, so I haven't completely wasted my
time...
47 f8=N+ ...
47 ...Kh8 48 Ne6+ Qxe8+ 49 Qxg7#
47 ...Kg8 48 Ne6+ Kf7 49 Rxd8 
But very importantly, there is one more varation, if the black queen has gone walk-about (i.e. 46 ... Qg5), where we don't even need our queen! 47 f8=N+ Kg8 48 Ng6+ Kf7 49 Rf8# So, what is my king move?
<46 Ke1 ...>
This stops all the nasty checks, except one and threatens 47 Qg6+ Kg8/Kh8 48 f8=Q#! <46 ... Rd1+>
<47 Qxd1 Qh5+>
Black gives up all chances of a win and tries for the draw by perpetual check! <48 Ke2 ...>
But white doesn't need its own queen due to <1 f8=N+ Kg8 2 Ng6+ Kf7 3 Rf8#>! 48 ... Qh5+ 49 Ke3! Qxf7 50 Qd8 Qxf5 51 Qd3
<48 ... Qg4+>
<49 Ke3! ...>
49 ... Qxd1 50 f8=N+ Kg8 51 Ng6+ Kf7 52 Rf8#
49 ... Qxf5 50 Qd3
<49 ... Qg5+>
<50 Ke4 ...>
Black is running out of checks!
50 ... Qh4+ 51 Kd5
<50 ... Qg2+>
<51 Qf3 Qc2+>
<52 Ke5 >
Time to check...
~~~
Black didn't see the threat of the under-promotion, so walked into it... |

| Jul-07-12 | | CHESSTTCAMPS: Black is up two pawns, but white has the trumps - two strong f-pawns, one that supports a checkmate on g6 and the other ready to queen. White only needs to deal with the rook check. It took me a while to see any possible difficulty after the obvious 46.Ke1
This leaves black without any useful checks and white has three serious threats: 47.Qg6#, Rxd8, and f8=whatever. Black can't defend, but does have a trick (variation G, below): A) 46... g5 47.fxg6+ Kg7 48.f8=Q#
B) 46... Qd6/f6 47.Qg6+ Qxg6 48.fxg6+ Kxg6 49.f8=Q is an uninteresting way to win. C) 46... Qg5 47.f8=N+! Kg8 48.Ng6+ Kf7 (Kh7 49.Rh8#) 49.Rf8# is more interesting. D) 46... Re2+ 47.Qxe2 has no entertainment value whatsoever. E) 46... Qxe8+ 47.f7xe8=Q ditto.
F) 46... Qe7+ 47.Rxe7 ditto.
G) 46... Rd1+! (the trick) 46.Qxd1 Qh4+ 47.Ke2 Qg4+ (uh oh - maybe black has a perpetual?) 48.Ke3! (nah) Qg5+ (Qxd1 49.f8=N+! *the point* Kg8/h8 49.Ng6+ forces mate.) 49.Ke4 Qg2+ (Qh4+ 50.Kd5) 50.Qf3 Qc2+ 51.Ke5 Qh2+ 52.Ke6 Qa2+ 53.Qe5 Qe2+ 54.Ke7 and black's out of useful checks. H) 46... other 47.Qg6#
Time for review... |
|
| Jul-07-12 | | CHESSTTCAMPS: G. 54.Ke7 should read 54.Kd7. |
|
| Jul-07-12 | | Patriot: I think white needs to try 46.Ke1. 46...Rd1+ 47.Qxd1 Qh4+ 48.Ke2 Qh5+ 49.Ke3. Black cannot capture the queen: 49...Qxd1?? 50.f8=N+ Kg8 51.Ng6+ Kf7 (51...Kh7 52.Rh8#) 52.Rf8#. So if white can get out of check he will win. 49...Qxf7 may be black's best bet which is losing anyway. |

| Jul-07-12 | | kevin86: A superclassic! Marshall promotes AND sacs his queen. Then the new knight and rook form the beautiful Arabian Mate! |
|
| Jul-07-12 | | TheTamale: Go, Marshall! What a game. |
|
| Jul-07-12 | | hrobert5: I know this is underpromotion week, and I may be missing something here...but, I went outside the box with a straight up queen sac: 46. Qe2 Rxe2 47. Kxe2 ??? Black can't respond with a safe check, so irregardless of what he plays I then 48. f8=Q+ and I like my chances in an endgame with Q & R to Q (with better position.) What are the flaws? |
|
| Jul-07-12 | | James D Flynn: White threatens mate in one by Qg6 but he is in check and must move his K or interpose with his Q. 46.Qe2 is no good because Rxe2+ 47 Kxe2 Qd2+ and Black has at least a perpetual. White can certainly afford to sac his Q for a R where his K cannot be effectively checked because he threatens to take the Black Q and also to mate by the under promotion f8=N+ , Kh8 Ng6+ Kh7, Rh8# or Kg8, Ng6+ Kf7, Rf8# . If he could sac his Q for R on e4 he would have a win because Black would have no good checks with his Q. 46.Ke1(not 46.Kg3 Qd3+ 47.Qf3 Qd6+ 48.Qf4(not 48.Kh3 Rh2+ 49.Kg4 Rg2+ 50.Kh3or Kh4 or Kh5 Qh2#) Rd3+(not Rg2+ 49.Kxg2 Qxf4 50.f8=N mates) 49.Kg2(not Kg4 h5+ gives the Black K escape squares via h3 and g4) Qd5+ 50.Kg1 Qxf7 wins for Black) Qd6 46.Qg6+ Qxg6 47.f8=N+ Kg8 48.Nxg6+ Kf7 49.Rf8# |
|
| Jul-07-12 | | waustad: Like some others, I saw the underpromotion, but didn't put it all together. |
|
| Jul-07-12 | | hrobert5: Yeah, I missed the pawn at c3 covering for Qd2+; should have known there was no other option but the underpromote! |
|
| Jul-07-12 | | BOSTER: <Calll> <A Marshall swindle>. <CG> shows <POTD> where black game has already lost, and this is a little bit disappointed picture. Because if they showed the pos.(see diagram) after 22.Rce1 with black to play, where black played <attacking> 22...Rd2, you would have another opinion.
But if they played <defensive> 22...Rd6 they would win.

The continuation should be such this. 23.Ne4 Rg6 24.Rf2 Qxf2+ 25 Kxf2 Rxg5 26.Nxg5 f6 27.Nf7+ Kg8 28.Nd6. |
|
| Jul-07-12 | | SuperPatzer77: White to move and win - see diagram below:

| Jul-07-12 | | ajile: Black was totally winning through most of this game until he started losing it with 38..Rd2. Position after 38.hxg5:

|
| Jul-07-12 | | gambler: Missed this one. Since fleeing with the king would lead to checkmate, I figured I should just interpose. Thi showever is losing due to the imminent thread of a promoting pawn by black. The mating combination is very nice and at least, I saw it, I just picked the wrong defense... |
|
| Jul-07-12 | | Marmot PFL: Not every day you see a queen sac plus an under promotion |
|
| Jul-08-12 | | LoveThatJoker: <SuperPatzer77> White can actually still win without his f7 pawn - in some instances it may be the only way to win. You should read all the most informed analyses before you make a statement such as, and I quote directly from your post, "White has to avoid losing his f-pawn on f7." My solution post proves that if need be, White should sacrifice his f7 pawn to win the game. This established, in the 46.Ke1 Rd1+ 47.Qxd1 Qh4+ 48.Kf1 Qh1+ 49. Kf2! is for sure the best move; but even here, 49. Ke2 wins easily for White. Therefore your statement of 49. Ke2 being a dubious move is totally erroneous! LTJ |
|
| Jul-08-12 | | SuperPatzer77: <LTJ> I bet my boots the American great Frank James Marshall would have disagreed with your line of 49. ♔e2 so, he himself preferred to choose the best move - 49. ♔f2!! instead of 49. ♔e2. It's because he wouldn't want to lose the White f-pawn on f7. <LTJ> Thus, I like Frank Marshall's brilliant move - 49. ♔f2!! better. Black tries to force the perpetual check but he runs out of the queen checks. <Sevenseaman>, <FSR> and I, <SuperPatzer77>, analyzed the great Frank Marshall's move - 49. ♔f2!! - This is called "Marshall Swindle"! <LTJ> I'm telling you that the great Frank Marshall's move 49. ♔f2 is a very clever move! SuperPatzer77 |
|
| Jul-08-12 | | LoveThatJoker: <SuperPatzer77> You obviously didn't understand my post! Once again, as I already stated in my first post to you, I agree that 49. Kf2!, in the 48. Kf1 line, is the best move. This said, your statement that 49. Ke2 is dubious is erroneous! I have proven that White can win without his f7 pawn; and once again, in some lines it is necessary to give up that pawn to win the game! LTJ |
|
| Jul-08-12 | | SuperPatzer77: <LTJ> I really understand your post. I just prefer Frank Marshall's brilliant move - 49. ♔f2!! (period). That's called "Marshall Swindle" - that's what I'm talking about. That's YOUR opinion I really understand. However, it is a little complicated, I admit. We really understand why the great Frank Marshall made a brilliant move - 49. ♔f2!!. We can ask the other grandmasters about that. They sure as heck can give us an excellent explanation. The game was played in 1898 - a long, long time ago. Please don't make any negative remarks about <Sevenseaman> and me. Just our opinion is different from yours. I really admire Frank Marshall's tactical skills. Please don't criticize anyone's opinion. Next time, don't be too defensive, OK?

| Jul-08-12 | | LoveThatJoker: <SuperPatzer77> I am glad that you now understand. If all you wanted to express is that you liked 49. Kf2! in the 48. Kf1 line, then that's all you had to say: You didn't have to say that 49. Ke2 is dubious because it is not - it too is winning! My original post to you was so as to correct you on your mistake and nothing else - period. I have made no negative remarks about you or sevenseaman. LTJ |

| Aug-04-13 | | Tigranny: Aren't there quite a lot of swindles that Marshall gets lucky in and exploits to beat his opponent? This game sure shows it, especially by how exposed the White king was... |

|

| | dernier loup de T: Faute de frappe que je corrige en vous demandant humblement de m'excuser: "gens una sumus"! Et j'en profite pour ajouter que Marshall fut un grand champion américain des arnaques, ce qui n'enlève rien à son mérite de tacticien émérite! |
