I like it. What does this mean:"Opening suite depth is set to 100 plies" seems like a lot of "plies" - maybe you mean 100 different openings?

I have found sacrifices and body contact checking to be very useful. Note at move 17 SF thought it was winning , but game was over by move 26.

Contact check is indeed one of the eval features that helps in the evaluation. It can be safe contact check or an unsafe contact check. The latter disrupts the current defense structure of the king.

BTW where do you base the number 1500 in Ladder Level 1500?

BTW where do you base the number 1500 in Ladder Level 1500?

Not a 100% sure I am answering question. First I just copied the ladder option from SF sse. In the sse version , the Ladder rating was initiated at 1200 based on 64 nodes analyzed. Not calculated sceintificaly by any means , just a gut feel on how it played and more importantly how levels 1600 and 1700 played. Base on the premise that doubling of speed , or in this case nodes raises ELO 100 points, which would mean every 25 ELO would increase the nodes roughly by 19% ( the precise number is used the code ) so 1.19^4 ~= 2. So level 1200 is 64 nodes , 1225 is 64 * 1.19, level 1250 is 64 * 1.19^2, level 1300 is 128 nodes ( double level 1200 or 1.19^4 * 64 , all the way up to level 2600 which happens to be about 1 million nodes . Level 1600 is about 1000 nodes which is about the strength of a average club player. Hopefully I answered your question

Is SF sse a zh variant too?

I plan to run Sf zh with ladder to different engines I have in blitz rating list, which is based on Sjeng 11.2 set at rating 2300 - my estimate of its blitz fics rating.
