{ 1. Who is this study for?
— For people with any rating who know the Antichess rules and how the chess pieces move.
Make sure you know the “en passant” and “fifty-move” rules, otherwise google them.
Google “chess notation” if you don’t understand what “1.e4?? b5!” means. }
1. Be2 { 2. My chess rating is very low. Is it possible to reach 2000 in Antichess?
— Yes. It’s much easier than 2000 in Chess. Many strong Antichess players have their chess rating in the range from 1000 to 1300. } 1… Ke7 { 3. I heard Antichess is solved. Isn’t it too boring to play the variant when Black can’t win?
— There is a proof that Antichess is a win for White with 1.e3. However, you should memorize the right moves for about 900 million positions. If you think this is enough, you’re wrong. Yes, most of those “right moves” lead to a win (sometimes more than 100 moves are required). However… } 2. Nc3!! { the only move! } 2… Kf6 { However, there are a few lines leading to positions in which only 4 pieces are left. You are supposed to know how to win in those positions.
Do you know how to win in this particular position? … You are not alone, even the best Antichess players will hardly win in this position, playing against Stockfish (remember the fifty-move rule!).
Scroll down the solution. } 3. Kb5!! { again, the only move! } 3… Kg5 4. Bc4 Kg6 5. Bf1!! Kg5 6. Kc5 Kh4 7. Bc4 Kg4 8. Ba2 Kh4 9. Kd6 Kg3 10. Ke7 Kg4 11. Kf7 Kh4 12. Ke6 Kg3 13. Kf6 Kg2 14.

Ne5 Kg1 31. Kd3 Kh1 32. Ke2 Kh2 33. Bb1 Kh1 34. Bf5 Kg1 35. Kf2 { 4. Why then do strong players not like to play with Black pieces?
— From Watkins’s solution http://magma.maths.usyd.edu.au/~watkins/LOSING_CHESS/WEB/browse.php?e2e3 , White can always learn the right move in a particular position, and Black is then forced to look for another sequence of moves in which White doesn’t know how to play. } 35… Kxf2 { Moreover, strong players do not need to memorize all 900 million positions. They only need to remember the sequence leading up to the position they know how to convert to a win. } 36. Nf3 { 5. So, are White pieces preferred?
— Absolutely if you are a 2300+ player. However, let’s look at the Antichess World Championship 2018. In the match for the crown, two finalists played 40 games. What percentage of White wins do you think was there? 95%, 92%, 90%? } 36… Kxf3 { Wrong! White won 53% of games… } 37. Bg4 { If you’re interested, Black won 38% of games. The rest was drawn. } 37… Kxg4# { This is the fastest (most optimal) win possible from the starting position! } *

{ This is a rare endgame. It is here only to practice your attentiveness. The cost of a blunder in Antichess is much higher than in Chess.

The idea here is similar to the Rook vs King endgame. But here you create a bounding triangle, not a bounding box. }

{ OK, endgame is good, but I usually lose in the opening. What should I do?

Stop losing, start winning. Easy!
But seriously, let’s first take a look at how not to play in the opening and how to win if your opponent makes blunders.

We’ll talk about opening ideas later. At this stage, it’s not so important. Just remember, 1.e3, 1.c4, 1.g3, 1.Nh3, 1.a4, 1.b3 are good, and 1.d4, 1.e4, 1.d3 are bad. } { [%cal Gc2c4,Gg2g3,Gg1h3,Rd2d4,Rd2d3,Re2e4,Ge2e3,Ga2a4,Gb2b3] }

{ 1.d4 is the easiest opening. I mean it is very easy to win when your opponent plays 1.d4. }
1. d4?? { Why is this a blunder?
a) White opened his bishop and Black can place a piece on g5 (h6 is protected by many Black pieces, it’s not your choice).
b) White pushed the pawn too far. Now Black can sacrifice his e or c pawn.
I’ll show the simplest but not optimal sequence. } { [%cal Gc1g5,Gd4e5,Gd4c5,Yg7h6,Yg8h6] } 1… e5 { This is the best move. Why? Because it opens your bishop and queen. It would be dangerous if White could use this, but he is forced to take the e pawn. } 2. dxe5 { In Antichess, it is very important to see all open pieces, yours and your opponent’s! In this position, you should see that the White queen attacks the d7 pawn but the pawn is protected by 4 pieces and therefore you can’t take advantage of it. Your options are 2..Qg5 or 2..Ba3.
2..Qg5 is very good because you can turn the White bishop into a loose cannon. } { [%cal Gf8a3,Gd8h4,Yc1h6,Yd1d7] } 2… Qg5 { Remember that bishops are very dangerous in the opening. If 3.Qxd7, take the queen with the bishop or king. Do you see why 3..Nxd7 would be a blunder? Yes, you must always see which squares your pieces are attacking or will be attacking (targeting)! } 3.

4..Nxd7 is not very good because it would force the e5 pawn to be taken next move. It actually works but you have to calculate this!

{ What to do next?
The middlegame consists of two parts: strategy and tactics. Taktics are more important if your rating is below 2100. We’ll discuss tactics in the following chapters. But what to do in positions like this? Let’s discuss the basics of the Antichess strategy in this chapter. }
1. Bh3 { As you remember, bishops are dangerous. If the position is far away from the endgame, you would prefer to sacrifice your bishops. Therefore, one should always look for a position in which it would be safe to sacrifice the bishop.
This move looks dangerous, but it works! After 1..Ng4 Bxg4, all squares targeted by the bishop are protected twice.
Remember this tactical idea: attack squares protected twice! } 1… Ng4 { To understand the strategy, you should know the relative value of the pieces on the board. Stockfish says:
Opening/Midgame: King > Pawn > Queen > Knight > Bishop > Rook
(in the opening, you want to lose bishop and keep king)
Endgame: Knight > King > Bishop > Rook > Pawn > Queen
Do you see how much the value of the pieces differ depending on the stage of the game? This is important! } 2. Bxg4 { In addition, value of the pieces highly depends on the position. Until you are a 2200+ rated player, I’d recommend the following values:
Opening: King > Queen > Rook > Knight > Pawn > Bishop
Midgame: King > Rook > Pawn > Queen > Bishop > Knight
Endgame: Rook > King > Bishop > Queen > Knight > Pawn
which are wrong according to the engine. The position of the pawns there is questionable. } { [%cal Gh7h5] } 2… Nd7 { For example, according to the values, you might think that this move was a good one. But, in fact, it was very bad. The closer you are to the endgame, the less valuable the pawns become. Black has 7 pawns whereas White has 5. Losing the knight, which could be useful in combination with rooks, Black brings the endgame closer. What does he intend to do with extra pawns? } 3. Bxd7 { Pawns are important in the opening because they easily stop possible attacks, for example, when your opponent uses the queen. In the midgame, you should prefer to have connected pawns and never isolated or doubled pawns. In the endgame, you should prefer to lose all your pawns or promote them as soon as possible. } 3… Kxd7 { In the opening, queen is able to create a mess in the camp of the opponent, open dangerous lines or capture opponent’s king, which is very important. But in the midgame/endgame, it is very dangerous. You should look for ways to safely get rid of it. } { [%cal Gd1h5] } 4. Nc1 { [%cal Gd1h5] } 4… h5 5. Qxh5 gxh5 { To improve the mobility of your pieces, you should look for ways to gain a space advantage. } 6. d3 Rab8 7. Nd2 Ra8 8. f3 Rab8 9. Kf2 { It is very difficult for Black to push his pawns. Your connected knights are very strong! } 9… Ra8 10. Ne2 { Why are these green moves good for Black?
Because of your tactical idea Rg1! It is a very common pattern (tactical idea). } { [%cal Gh8h7,Gh8h6,Gd7e8,Gd7d8] } 10… Rab8 11. Rg1 { You attack a square protected by two rooks.

At the moment, the slowest time control vs anti-bot is 180+180.
When playing casual games, you can set the appropriate level.
Everyone can win at level −9. Develop your skills and gradually increase the level: −8, −7, −6, etc. } 28… Nb5 { Do not forget to participate in tournaments.
Try to make fewer mistakes, especially in winning positions.
