And the Ippolit author is...

[Graham Banks]

id name Kaissa 1.8a
id author Vladimir Yelin

Yelin's engine Kaissa2 was not a clone and played at 2100-2200 level.
When he renamed it to Kaissa it was already (probably) a clone of Crafty (?).

Some people (including me) recommended him not to use the honest name of first Soviet chess program. After that he renamed his engine to Patriot.

Hi Vladimir,

say hello to Azaad for me.

Cheers,
Graham.

The executable at ks_sell/kaissa.exe even runs on my machine and can play chess
The only problem is alphabetical symbols or pseudographics instead of piece images on the board.

First contact from my side was during Patriot 1 Time. We all thought it is clean. Patriot 2 was a copy of Toga with some formulas to change score and depth. I think for depth 3 was added, and the score had a factor of 1.5. The rest was identical.

After the Patriot 2 desaster I took a closer look on Patriot 1, and there where similaries to Crafty. It was based on Crafty but with many changes. But the frame was Crafty.

After Patriot 2 he released a new version of Kaissa, and it looked like Patriot 1, and I don't think he removed the Crafty stuff. Later it supported UCI, and a the traces of Crafty vanished, but still there where a few of them visible, like move generation.
