It was discovered that e3 is a win for White: http://magma.maths.usyd.edu.au/~watkins/LOSING_CHESS/ICGA2016.pdf

I cannot really speak from my own experience, but there seems to be some very decent sites about Antichess. Here is what this one has to say about the opening: "Just like in chess, the main goal in the Losing Chess opening is development of the pieces. One has to be careful, as the starting position is quite volatile, and some first moves even lose ...

Professor Mark Watkins announced he had found the solution to Losing Chess in October 2016. Regardless of what Black plays, White can force a win beginning with 1. e3.

In my opinion, this is a very difficult question, since the piece values in antichess are not as static as in normal chess and usually highly depend on the game phase and position. However, there are some rules of thumb which pieces tend to be stronger or weaker, see, e.g., http://poincare.matf.bg.ac.rs/~andrew/suicide/StanGold/theory.htm. You can also try ...

https://github.com/ddugovic/Stockfish has what you want. Not an offical version, but should be stable for production.

To the third question: yes, there are. I found one, at least. This page should interest you. It has some articles, proof trees and is updated regularly, it seems. The articles and files on the page also give some indication as to the first two questions, for example the number of nodes and size of the proof tree files. It appears that game as a whole is ...

Your summary of the rules left out an important one, namely, how else can you win a game besides being stalemated. The answer is that the player who runs out of men wins. (I suppose you could consider having no men to move a kind of stalemate.) And "antichess" is a new name for the chess variant traditionally known as Losing Chess or Giveaway Chess. The ...

One useful tactic is to try, as far as possible, to leave exactly one of your units en prise. That forces your opponent to capture that unit next. So to a large extent you're in control (and are losing units). By contrast, if you were not so careful as to which units of yours were en prise, then if ever two or more of them were, then your opponent can choose ...

Sjeng supports losers chess too since release 9.

For question 3, just as GloriaVictis said, losing chess is almost solved. Only 1.e3 b6 is still being solved now. All others have already been proven to be a black loss. Based on how fast each response to 1.e3 (generally at most several months) is solved I believe we will see the solution of losing chess this year. Also the solution is likely to be a white ...

Antichess, which I call giveaway, values should be derived from their mobility just like in most chess (variants). The pawn has the least mobility and therefore is the easiest to force to take. The sliding pieces come next, although most people would claim that they it's easiest to force them to take, they are mobile enough to choose their path of ...

I've never used it myself, but I believe that Wizard is a strong and free Loser's Chess engine. An undated reference table on the same website shows that Wizard used to be one of the strongest Losers engines on FICS - however, I understand that the creator passed away many years ago so it may be outdated.

The WinBoard Alien GUI is reputedly better suited to playing chess variants than the standard WinBoard is, but that's just an observation. As to engines that play Losers Chess within a WinBoard environment, it seems that the answer is unfortunately no: Sjeng seems to be the strongest of these (within context), though at least OliThink seems likely to give ...
