Dasher Bot is overtuned.

Sort:
Snorghma

The Dasher bot is noticeable harder than 1600.  Below is a game of the Dasher bot (black) against a stockfish bot (white) at level 3, estimated 1600.  It cleanly beats the estimated 1600 stockfish bot.  I've played this thing over and over and over again for the last few days.  I can consistently beat the other normal elo 1600 bots, but not this one.  I think it's elo is higher than listed.

Dasher? I couldn't find it in the list of bots.

ICC had a Dasher as I recall.

Snorghma

Oh no! 

Do you know about "en passant" captures?

I beat him after 15 tries

Snorghma

I am able to beat him, but he is significantly harder than the other 1600 bots and I tested him against the 1600 stockfish bot and he beat it pretty easily with black.  I don't know what exactly his strength is or how is ranking is determined here, but he seems stronger than 1600 as ranked here.

I personally believe that Dasher is hard, although not impossible. I cleaned him in one try(I play around 1880 range)Fun Fact: I beat Beth 15 yesterday!
