Incredible Double Exclamation Move That Both Players Missed: A Rubinstein vs A Mund (1906)

Hello everyone and I have a very exciting chess game to show you by Akiba Rubinstein and in this chess game his opponent was August Mund. Rubinstein had the white pieces and this chess game was played in 1906. Let's see what happened in this very exciting and instructive chess game. e4 by Rubinstein e5 knight to c3 this is the vienna game knight to f6 this was the most common reply falkbeer variation and f4 this is similar to king's gambit and black played d5 the falkbeer variation also similar to the king's gambit falkbeer counter gambit we have f takes on e5 the classical main line knight takes on e4 but let's take it back in here capturing the pawn and accepting the gambit is a very bad move here this is a bad move because of e5 and forcing black to go back to g8 that is forced and white is better and if queen to e7 queen to e2 and again forcing black to go back and also white has this space advantage white is better and white is going to continue developing his pieces this is a very bad position for black already in the openings this is why not accepting but d5 common move the classical main line knight takes on e4 and knight to f3 and this is the main move in this position a very common move but queen to f3 this is the pulse and attack or d3 vienna gambit oxford variation is also very common in this position but rubinstein played knight to f3 bishop to e7 and we are reaching to the breyer variation of the vienna gambit d3 and kicking the knight back with getting strong center and space advantage on the board advantage for white bishop to d3 castling f6 of course which makes sense striking white strong center queen to e2 knight to c6 developing and attacking the d-pawn developing and defending but f takes on e5 knight takes on e5 and leaving the pawn but we have knight takes on e5 why not knight takes pawn the free pawn then queen to h5 is very dangerous for black and if you push the pawn we can sacrifice and get in it is going to be very dangerous for black i think if pushing the i believe queen to g6 should be losing you can even sacrifice the bishop so this is almost impossible to defend very difficult a very difficult position for black already this is why rubinstein is sacrificing the pawn with opening his queen the diagonal to the queen but knight takes d takes on e5 and c6 did rubinstein blundered in here how about d4 forking two pieces then again queen to h5 is bad news for black now threatening checkmate the rook is also occupying the f file and if g6 then we can sacrifice the bishop and at least white has perpetual check white can even try to win when the black king is very badly exposed but that is going to be very risky and if blocking with the knight then bishop to h6 and how to defend now it's not easy isn't it and this is losing for black and also because of this pawn you can't defend this is winning for white and that e pawn looks like a bone in the throat cramping black space okay but this is why we have c6 maybe black should considered actually g6 clamping on h5 but black plate c6 and rubinstein plate can you guess the move it should be very simple queen to h5 of course and threatening checkmate g6 but bishop sacrifice pawn takes check blocking with the knight and bishop to h6 rook takes on f1 rook takes on f1 this is actually forced checking the king and defending with the queen or queen to c7 this is a very interesting position can you see the next move for white this is very interesting position because rubinstein missed the best move in here he completely overlooked an incredible tactic in here which is interesting because rubinstein was one of the greatest strategic minds in the history of chess but unfortunately he missed he missed an incredible move which could make this chess game one of the immortal chess games of rubinstein let me show you what rubinstein played actually white is still winning white has a better position white is a piece down but white is going to get material white is going to get back the material very quickly rubinstein played e6 with threatening instantly on the spot after rook to f7 it's all over and if queen takes pawn deflecting the queen we can take the knight checkmate what else a bishop takes is forced bishop takes knight and if queen takes which is very expected a normal looking move then queen takes and this is all over king to h7 well you can even lift the rook up and go after the king or you can play simple rook to f7 pinning the queen to the king and this should win for white this should be winning and if king to h8 then rook to f5 and threatening rook to h5 and defending is not easy at all it's impossible actually and but what did rubinstein missed in this position now let me show you the best move for black instead of queen takes bishop bishop to f5 was the best move and if queen takes bishop king takes on g7 and black is still fighting but white is better and bishop to f5 and if rook takes here this is very bad back rank checkmate white is getting back rank checkmated black missed bishop to f5 exclamation point not just black but rubinstein missed this too this is why he pushed the pawn and this is why he just completely missed bishop takes bishop takes and bishop to f5 which is still winning for white a little bit slightly as a slight advantage for white after sorry after queen takes bishop king takes bishop white is still better because white is a pawn up but it's not winning immediately okay but this is the big question what did rubinstein missed in this position well instead of pushing the e pawn instead of pushing the pawn he should have played knight to e4 double exclamation point and did you see this move and did you see more importantly the idea behind this incredible sacrifice well let me immediately immediately show that queen takes pawn is a grave error that knight to f6 checkmate and if king to f8 checkmate again this is why queen takes pawn is out of questions and why it is threatening knight to f6 and how about capturing this annoying knight if pawn takes knight then this time pushing the pawn is a very very different story threatening rook to f7 again winning instantly and actually the idea is this this is blocking the back rank problem incredible isn't it a black's own e pawn is blocking the back rank checkmate idea because this time after bishop takes bishop takes knight and there is no bishop to f5 because we can take it with the rook and this is extremely dangerous for black because if you take then we will check and you can see that it's the same problem because if king goes here then rook to f7 and if king to h8 then rook to h5 and it's all over i think this is why rubinstein should play knight to e6 first then he should push the e pawn and this was very difficult actually this was a very difficult chess problem okay anyway interesting in the real chess game we have e6 immediately and this just completely overlooks bishop to f5 idea but black didn't see this as well because you can take the bishop with the rook but if queen takes then queen takes and this is just all over as well anyway king to h8 rook to f5 but this is still a winning of course for white after queen takes bishop and then king takes white is better because white is a pawn up okay did you see the idea i hope you enjoyed watching this and i hope to see you again thanks for watching and bye bye
