Took me a while, but I believe the winning continuation is 1.Nc7+ Qxc7 2.Bxf7+ Kxf7 3.Qd5+ Ke8 5.Qe6+ Be7 6.Qxe7#

[@PedrinhoCruzeirense]

Nc7+ wins by force. But the beautiest move is 1.Qd5!! It threatens mate on f7 and black can't play 1 ... Qxd5, because of 2 Nc7 mate!! So, the only move for black is to play 1 ... Nxg5 (defending f7), but then white captures the black queen (not mentioning the poor juicy rook at a8). If I was on this position as white, I would prefer this line, even after seeing the Nc7 mate line, just for fun and beauty.

[@jenishajackrit9546]

I see that after all ur moves King can go to e8 @pedrinho paquiderme ans is correct one

[@C0RY.M]

@@jenishajackrit9546 Scaly Goose is correct. My original thought was 1. Nc7+ Qxc7 2. Qd5. From here, I didn't see a way for black to defend against checkmate, but then I realized they could block the black diagonal with f6.

[@GMIgorSmirnov]

Well done!

[@KYYYYG]

Lmao, this one is actually what i've calculated

[@ReflectionOcean]

- Evaluate the material balance to understand the position's urgency (start: 0:52). - List candidate moves before deep calculation to stay organized (start: 1:18). - Focus on enemy territory and consider forcing moves first (start: 1:48). - Calculate variations until the end of the forcing line for accurate outcomes (start: 5:03). - Prioritize moves using positional understanding to simplify calculation (start: 6:30). - Keep the opponent's king restricted to develop your attack (start: 10:17). - Reorder moves to make identified tactical motifs work (start: 13:00).

[@MyBiPolarBearMax]

This is excellent. I made the mistake of seeing the motif but not finding a way for it to work. I kept seeing ways to gain material advantage but didnt combine the knight sac WITH the bishop sac to find mate.

[@justsomeboyprobablydressed9579]

@@subramanianponniah1238 Very good! That works too, but it takes longer to win (look for White's move to keep from getting mated immediately). Notice in the sequence I gave, every move by Black is forced (one move on each turn). It's a forced mate-in-5.

[@cikonianiggra1415]

@@subramanianponniah1238 But after NxBg5 there is not check mate, you must play Qxc6 and the play is going on for some time.

[@maryhanisch9979]

Yes, in the puzzle, every move is forced. I love it!

[@laurivaara3177]

Sacrificing the white queen on d5 is the way to go. If the black queen captures, knight to c7 is a check mate. If the white queen is not captured, queen to f7 is a check mate.

[@kevinhodgson2990]

I wouldn't call it a sacrifice since the d5 queen is protected by the bishop. Excellent move creating 2 checkmating threats. However black can just give up his queen and take the g5 bishop. So you have 1. Qd5 Nxg5 2. Qxc6 Rb8 3. Nc7+ Kd8. A winning advantage for sure but I don't see a quick finish. I think 1. Nc7+ gets the job done in 6 moves.

[@eddiescherer]

NxB and the game goes on. It´s a beatiful move, but not mate.

[@GJAkuo]

Queen d5 is met with Knight captures g5 and the game goes on. Mate is out of sight.

[@fredtaylor9792]

Great information! Love the way you explain it. Also, after doing a lot of puzzles the last few days, I figured out that first position checkmate in about 10 seconds. Puzzles aren't everyone's cup of tea but they really get you in the right mindset... my humble opinion.

[@jimkyle8008]

The solution to the puzzle at the end of the video is as follows: 1.Nc7+ Qxc7; 2.Bxf7+ Kxf7; 3.Qd5+ Ke8; 4.Qe6+ Be7; 5. Qxe7 mate. I'm happy to say that I solved all the problems quickly. I must be getting better. Thanks, Igor.

[@mikestock969]

Awesome timing of this video 👌👍😊 Truly appreciate your help.

[@GMIgorSmirnov]

[@smithyq6335]

Final position is interesting. Looks like a Sicilian, Sozin variation where Black has played ...b4 to chase away the Nc3 and then grab on e4. The solution is quite fun: 1.Nc7+! (forcing move, King cannot move) Qxc7 2.Bxf7+! (forcing move, again only one reply) Kxf7 3.Qd5#. Interestingly, I think Black saw this. In the diagram, the last move was Qc7-c6, trying to cover d5. It looks like Black could just take the knight with ...axb5, but that would allow Bxf7+ and Qd5# immediately. So Black saw the threat and tried to stop it, but 1.Nc7+! pulls the Queen away from d5 immediately. Must have been very satisfying to play as White!

[@simontang2944]

I like it! Think it needs to continue 3... Ke8 (only square to get out of check), 4.Qe6+ Be7 5. Qxe7#

[@smithyq6335]

@@simontang2944 Nice. Thanks for the correction, I somehow completely missed that Ke8 was possible!

[@garysturgess6757]

I found the immediate 1 Bd5 which traps and wins the queen, but of course checkmate is stronger. :)

[@GMIgorSmirnov]

it was an insightful analysis of the preceding moves!

[@smithyq6335]

@@GMIgorSmirnov I tried re-creating the game based on those hints. Looks like White offered a piece with 12.f5!?, which Black tried to decline with the "safe" 12...e5, which allows the 13.Nb5!! shot. After 13...Qc6, we reach the puzzle position: 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. Bc4 b5 8. Bb3 Nbd7 9. O-O Qc7 10. f4 b4 11. Na4 Nxe4 12. f5 e5 13. Nb5 Qc6 The move order might not be right, but we reach the puzzle position.

[@CaptainAndy99]

Great video, thank you very much.

[@thedspenguin]

on the second puzzle I calculated every variation, as you teach, and Black can defend (doesn't need to take the bishop with the pawn), meaning it's not necessarily mate.

Fairly easy and straightforward examples with a clearcut one viable line worth calculating.

13:53 Nc7+ forces Qxc7, then Bxf7+ forces Kxf7, then Qd5+ forces Ke8, Qe6+ forces Be7, allowing Qxe7#.

[@sensitiveecoterrorist]

For the third scenario I see a number of lines: One is 1. Nh7 Kxh7 2. Rxh5+ Kg8 3. Qh6… at this point I don’t see any way for black to escape mate on Qh7 supported by Rook or Bishop. Though admittedly Kxh7 is a blunder here… Another is 1. Rxh5 g6xh5 2. Ne6+ - if black moves king back to either g8 or h8 or captures knight with bishop, mate is unavoidable after next queen check. If black captures with the pawn, then its a short chase along the 8th rank. EDIT: I’m happy that I found the right line, but it took way too much calculating/overthinking positions, which takes up time and spends a lot of mental energy in game. Noted for future games! Thanks.

[@iankemp1131]

Of course a key point is that these positions don't arise by accident. You will have had to plan and work towards them, otherwise they won't happen. Even grandmaster Spielmann said of world champion Alekhine, "I can see the final combinations as well as he can ... but I can't get into the same positions". In the first example, Black will have been positioning his R, Q and B over previous moves to prepare the winning combination.

[@RomelTVGuide]

The solution of the last puzzle can be 1.Qh5 threatening mate, if blackplays g6 then 2.fxg6 any pawn of black captures(f or h pawn)3. Bf7 is mate since rook supports the bishop. I am not sure about the answer, if any one finds it please reply me.

Very good video. You have excellent English. I did think you were saying "motif" when you showed the word "motive" in example 5. The first is a pattern in art and the latter is motivation so I think "motif" is used in chess.

[@andrewandsueniemeyer6958]

I agree Qd5 leads to a forced mate, and the Nc7+ works I think Qh5 is also good, although a violation of the video. Checks are covered by the knight on a4, g6 results in a recapture allowing bxf7#

[@vivektulja4516]

Very good video. Thank you, Igor. My two most favorite players are Tal and Ivanchuk. What I find most amazing about them is that they see a winning combination in moves that on the surface look like losers. And I always wonder how do they do it. Maybe that's what genius is all about!

[@thiagoserafini4215]

14:02 I calculated 1. Bxf7+ Kxf7 only move. 2. Qh5+, if they block with the pawn they're worse, but if they play 2... Kg9 black's better. So i changed the order of moves. 1. Qh5, it's a checkmate treat, black can only block with 1... g6 2. Bxf7+ Kxf7 only move and 3. fxg6 and white seems to be winning... I think. The bad think is after 1. Qh5, they can block your dark square bishop with Ne or Ndf6, making breathing room for his king.

[@PedrinhoCruzeirense]

4:10 Bxh6 is devastating, because accepting the sacrifice with xh6 leads to Nf6+, forcing Kh8, and there is no way to stop Qe4 ... Qh7#. Black should therefore decline the sacrifice, but remains down a pawn, and has a terrible position.
