I often use the Pulsar engine to analyze my Atomic games for better play (post-mortem). I definitely learn something, since I am not as smart as Pulsar. I am interested in doing the same thing for Losers chess. Pulsar is not very good at Losers, but Sjeng is better at this variant.

I use both Pulsar and Sjeng under the WinBoard interface. Does anyone know of stronger engines that play Losers chess? I have Googled for several days, did not find any. Both Pulsar and Sjeng are free, but I would be willing to buy better software.

PLEASE NOTE Many sites have confusing terminology for variants. Losers chess is not the same as Suicide or Giveaway. In Losers chess, the King can be checkmated, and you must respond to check. This makes a big difference in the strategy for Losers chess compared to Suicide chess.

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the strongest Losers engines on FICS - however, I understand that the creator passed away many years ago so it may be outdated.

I am familiar with that web site. It appears that Wizard does NOT play Loser's Chess, but instead "Losing Chess" or Suicide Chess. – Rick G Jun 27 '13 at 20:11
Ah, I apologize for my misinformed answer. Thank you for letting me know. I'll provide an edit as soon as I find another suitable engine. – Andrew Ng Jun 27 '13 at 20:27
