♡ 17 ( +1 | -1 ) Got to remember ...after Rxf2, the open f-file will work BOTH ways! :) So ...Qd8+ ! looks mean Kf7 Rxf2+ or maybe even Qd7+ or Rc7+ instead. But, I can't see that far before dinner!
♡ 45 ( +1 | -1 ) PS//I have a FIDE Master friend who tells everyone, "Always Check for Check!" as part of their procedure for every move made ... which sounds so simple, but THEN I remember all the games I've tossed out the window from missing some diagonal check by a Q or B ... and realize it would probably save me several dozen rating points in a year of heavy tournament play. So the only response I have is, "right you are Mike"! }8-))
♡ 72 ( +1 | -1 ) The line suggested ...by ccmcacollister looks pretty good for White, to me! 23...Ne2ch 24.Kh1 Rxf2 25.Qd8ch Kf7 (forced, since ...Rf8 won't do!) 26.Rxf2ch Rf3 (26...Kg6 27.Qg5# or 26...Qf3 27.Rxf3 Rxf3 28.gxf3) 27.Rxc3 Rxf2 28.Rf3ch etc. So Marshall wasn't just playing to the gallery with just about the most aesthetically pleasing move ever seen on the chessboard. It doesn't lead to mate, but a winning endgame: 24.Qxg3 (both pawn captures lead to a swift quietus, though! ... and if 24.Qe5 Ne2ch and mate next) 24...Ne2ch 25.Kh1 Nxg3ch 26.Kg1 Nxf1 27.gxh3 Nd2 28.Rc7 Rf4! 29.Rxb7 Rg5ch 30.Kh1 Nf3 31.Rb1 Kf7 when Black can probably keep White's K locked up whilst he manoeuvres his own K to pick up the stray c- and f- pawns.
♡ 31 ( +1 | -1 ) 23...Ne2ch 24.Kh1 Qg3...... Transposes into the "game continuation", to the win of a rook after 25.Qxg3 Nxg3ch 26.Kg1... But I doubt there would have been any shower of coins (apocryphal or otherwise) had Marshall played it this way, since this move order obviates the pawn captures that gives 23...Qg3 such eclat.
♡ 7 ( +1 | -1 ) Of course! Silly me...23...Ne2ch 24.Kh1 Qg3 25.gxh3 ... I was right about the shower of coins though... ;-) Ion
♡ 57 ( +1 | -1 ) Well...After 23... Qg3, Chessmaster quickly decides that black and white will trade Queens and Rooks, so the move doesn't win a rook. I can give the exact moves of that analysis if you want.
After the alternative line, Chessmaster has white going into the end game with a Queen and Rook against a Knight, eventually winning the knight and then checkmate. So no, there is no forced mate after the alternative line. Of course an opponent can always make a bad move that leads to either mate or a strong advantage, so you never know.
♡ 91 ( +1 | -1 ) ultimatt...You are right: the sacrifice doesn't actually win a rook (though I'm not sure who said it would - I'm fairly sure I didn't! ;-)) After 23...Qg3, Black threatens mate by 24...Qxh2# How to stop the mate? Let's eliminate the pawn captures first: 24.fxg3 Ne2ch 25.Kh1 Rxf1ch 24.hxg3 Ne2# How about the queen capture? Check out my earlier posting with this line 24.Qxg3 Ne2ch 25.Kh1 Nxg3ch 26.Kg1! (26.fxg3 Rxf1#) 26...Nxf1 27.gxh3 Nd2 retaining a knight extra. In an earlier posting I gave as a possible continuation 28.Rc7 Rf5! [mis-typed as Rf4!] 29.Rxb7 Rg5ch 30.Kh1 Nf3 31.Rb1 Kf7 etc. w The threat of advancing Black's king to h3 against White's imprisoned monarch will probably force White to give up his c-pawn. The idea is 32.Rc1? (say) Kg6 33.c4 Kh5 34.c5 Kh4 35.c6 Kxh3 36.c7 Rg2 37.c8=Q Rxh2# OK, this is all speculation, I agree! There is a fourth possibility: 24.Qe5 Ne2ch 25.Kh1 Rxh2# or 25.Qxe2 Qxh2# Cheers, Ion
