{ This famous "windmill" combination was first played in the game between Mexican Champion Carlos Torre and by then former World Champion Emanuel Lasker (Black) in the Moscow International, 1925. White's Bishop on g5 is pinned against his Queen, but such a "relative" pin (rather than the "absolute" pin on the King) can be broken if the price is right! Find a good move! } 1. Bf6 Qxh5 { Our Queen has been taken and how can we take back the enemy Queen? } 2. Rxg7+ Kh8 { After that, should the move Rook go? } 3. Rxf7+ { (Because the King was in check, the opponent's King was forced to return to his place.) } 3... Kg8 { Of the two good steps, which one is the best! } 4. Rg7+ Kh8 { The next step before attacking his Queen. } 5. Rxb7+ Kg8 { Check again! :) } 6. Rg7+ { (The Rook slides back and forth, snatching material.) } 6... Kh8 { Well, then the steps to win the price! } 7. Rg5+ Kh7 { Then the next step ... } 8. Rxh5 Kg6 { (Lasker fights on ingeniously ---- this double attack by the King wins back a piece.) Then look for the steps in question, namely .... } 9. Rh3 { Right! } 9... Kxf6 { Ok,Next..... } 10. Rxh6+ { with a decisive material advantage.(Torre - Lasker, Em., 1925) Thank you for working on this tactic. Hopefully useful :) by: Grand_pandamaster } *

This is the two steps checkmate! } 1.

up a piece for the attack, and continues the
"sac, sac, mate" with 1.... Rh1+ } 2. Kxh1 { After the King took the Rook, all that had to be done was to attack the King with him using ... } 2... Qh4+ { Check!

Qh5 { The checkmate is being held by the Queen but it is still unavoidable } 5... Qxh5 6. Re1 { Ok, now look for a two-step checkmate. Did you know? } 6... Qh2+ { Great! Now white move. } 7. Kf1 { Next..... :) } 7... Qh1# { Ok done.Well, This variation is long, because white has
some checks, and gives up his queen to
delay the mate, but the pattern is a good
one to know.

Qxf3 { After the Queen took your Knights, which Queen to take the best? Is it a Queen or a pawn? } 3. Qxf3 { Very nice! Now when you attack your opponent, you have to be careful about the counter threats from your opponent. Before you attack, you secure your King so that your opponent doesn't easily strike back. Then pay attention to the direction of the opponent's movement, whether you will be threatened or will you bring a checkmate to step forward. Therefore, don't be too hasty in realizing step ideas without checking them again. That is my advice for beginner chess players. Be careful in playing, don't immediately attack your opponent before your King is safe and you shouldn't underestimate your opponent or it could be that your opponent is the best.

{ This is an example of tactics found in the end game. To promote a pawn, the king must move in front of the pawn because if the pawn is in front of the king and the opponent king is in front of your pawn, then you will draw because your king cannot go forward. Therefore the King must move first and also must first oppose the opponent's King. If the opponent's King first opposes your King even though you are already in front of the pawn, then this will also be a draw. Now, try to win this endgame by not trying to draw. Which is the best move! } 1. Kd6 { Very nice! I explain again, the King really has to be in front of the pawn and the King must oppose the opposing King first so that the opposing King can't get close to your pawn. } 1... Ke8 { After your opponent's King leaves again, then your target is the King to be in the 7th line and next to the pawn row for promotion. Before that, your King has to be in opposition first so that the opponent's King goes to two places, left or right. If your opponent's king goes to the right, you must move forward in the opposite direction of the opponent's king and vice versa. } 2. Ke6 { Good move! Now your opponent's King must go right or left. If the opponent's king is to the right, surely your king will go to the left and occupy the 7th row and vice versa. } 2... Kd8 { If the opposing king goes to the left, then your king will go to ... } 3. Kf7 { Very good! Now the opponent's King must move away from the pawns and the promotion pawn line. Because the King can no longer stop the pawns and black will lose easily if you are careful with draws. } 3... Kd7 { If it's like this, you know what to do, right? } 4. e6+ Kc6 { Next move ... } 5. e7 Kc5 { Just one more move is ... } 6. e8=Q { Congratulations.

{ So, in this tactic, I will explain how to draw in the endgame of this section. If your opponent has one pawn, then the method is to wait for your opponent to make a mistake with the King still behind the pawn. To handle it, you do this by blocking the movement of the pawn in front of it. What is certain is that the opposing king must move sideways. When it is your turn to move, your King must move backwards and do not move backward to the side, must stay back in the pawn lane. As an example beside. } 1. e6 { After advancing the pawn, you must keep retreating in the direction of the opponent's pawn path. Because, if you step aside when your King steps back and gets stuck to the edge of the board, then you will lose in this endgame. Therefore, I recommend you to go straight back in the direction of your opponent's pawn. Now, it's your turn to move. } 1... Ke8 2. Kd6 { When your opponent's King comes forward, the way to draw it is to oppose the opponent's King first and make sure the opponent's King can't move forward so that your opponent's King can't occupy the 7th line. Now. Your turn to move. } 2... Kd8 3. e7+ { As the pawn advances, the most suggested move for a draw by black is ... } 3... Ke8 { Good move! Now, white can't do anything and can't promote his pawn. Whichever move white will make is a draw. Want the King to move to the Ke6, Ke5, Kd5, Kc5, Kc6 or also Kc7. All that movement is a draw. A Chess Master says: "That the most important part of the game between losing, winning or drawing is the endgame. The endgame must be carefully thought out to move towards victory and to move towards a draw in playing chess." That is why the end game is so important to learn and understand in everyone. Thank you for learning the tactical tactics of this end game. Hopefully the tactics are very useful for you or all chess players. :) } *

{ Although Bxc3 is often played in the Nimzo Indian, it should not be played automatically.

So e4 isn't a threat right now. Therefore, it is best to keep your dark squared bishop. The next plan is to play against the "hanging pawns" d4 and c4 with Rc8 and a timely d5! If Black can force White to have an isolated d4 pawn, that would impose a great weakness. } *

1. d4 Nf6 2. Nf3 e6 3. g3 b5 $5 { Now that White's plan is to fianchetto the bishop to the long diagonal, Black can safely take more control along the f1-a6 diagonal. b5 also prevents White from gaining space with c4 too. b5 gets the benefits of b6, and more. } 4. Bg2 Bb7 5. O-O c5 6. c3 ( 6. a4 b4 { The b4 pawn will continuously prevent Nc3. } 7. c4 cxd4 8. Nxd4 Bxg2 9. Kxg2 Qc7 { Black's position is comfortable } ) ( 6.

{ I have made strong claims that the Stonewall Attack is bad in my Kings Indian Guide, and I state my refutation there. However, since this guide is for Nimzo/Bogo Indian, I will not suggest a line that requires a fianchetto and largely different structures. The Stonewall is still refutable, and should not cause Black troubles } 1. d4 Nf6 2. e3 d5 ( 2... g6 { My recommendation in the Kings Indian Guide } 3. Bd3 Bg7 4. f4 O-O 5. Nf3 d6 6. c3 Nc6 7. O-O e5 { Disrupting the Stonewall structure } ) 3. Bd3 c5 4. c3 Nc6 5. f4 Bg4 $1 { Getting the bishop outside the pawn chain before playing e6 is essential } ( 5... e6 $6 { A Stonewall Attack player's delight! } 6. Nf3 Bd6 7. Ne5 { Objectively equal but the position is so much easier to play on the White side. } ) 6. Nf3 e6 { With the added threat of Bf5, trading off bishops. } 7. O-O Bd6 8. h3 ( 8. Nbd2 O-O 9. h3 Bf5 ) ( 8. Qe1 Bf5 ) 8... Bf5 { Offering to trade off your bad bishop for White's excellent one. } 9. Bxf5 exf5 10. Ne5 { Worry not! e5 is not an outpost for the knight. However, e4 is one for yours... } 10... O-O { The Bg4 move gives zero advantage for White. If you play e6 too early, White gets a monster knight on e5 and an uncontestable bishop on d3. } *

1. d4 Nf6 2. c4 e6 3. a3 { An interesting move that stops both the Nimzo Indian and Bogo Indian on the spot. So naturally, the goal is to force White into a line where a3 is not effective. I suggest the Benoni, where usually White will play a4 to slow down Black's future queenside expansion. } 3... c5 4. d5 ( 4. e3 cxd4 5. exd4 d5 ) 4... exd5 5. cxd5 b5 { Already a new type of position than typical Benoni structures. White's Nc3 is typically played early, so it's a real pain for White now to even develop the knight at all. } 6. Nc3 ( 6. e4 { Probably White's best try is to mix things up with e4. } 6... Nxe4 7.
