Thank you for these stockfish versions. I don't belong to a chess club , hence I play short games on line and longer games against computers.

So I appreciate weakened, handicapped programs.

Thank you for the ratings ladder and throttle options which I find very useful.

I was just wondering for any future versions if there could be an option for ladder ratings and throttle functions to not play instantaneously . Just like playing against a human.

I know the skill levels play with a natural delay but I think a more realistic game on hadicap levels is gotten from a program on full strength but with a reduced time for 'thinking' rather than having a program purposely picking a sub optimal move?

So throttle functions and ladder ratings but with a normal response delay may be a good option to better simulate a chess game if needed?

Just a thought
Thanks

I think that can pretty easily implemented, years ago, I had it in crafty se. I understand it completely why you would want that - I also prefer the shortened time allowed to think as opposed to deliberately picking sub optimal moves as well. I will soon have a Stockfish Crazy House version with the "ladder feature" as well. It will be a separate engine for now.
As promised , we have the latest Stockfish 8 sse with the "Ladder" and the new "Ladder Delay" uci options as well as the variant playing Stockfish 8 version with the same Ladder options.

Make sure you have the latest uci2wb (Source and macOS exe):
https://github.com/MichaelB7/Stockfish/ ... 7c084c.zip

This the xBoard.conf settings that works for the variant playing Stockfish for me to play crazyhouse under xBoard on mac OS. xboard version 4.9.1 is highly recommended for variant play.

Code: Select all

-fcp "/Users/michaelbyrne/cluster.mfb/stockfish-8-CH" -fd "/Users/michaelbyrne/cluster.mfb" -fUCCI -variant crazyhouse  -firstFeatures variants="crazyhouse" 
Summary:
"Ladder Delay" is a sleep function used in conjunction with the uci option "Ladder". Ladder reduces the number of positions for human play. "Ladder Delay" wait will force Stockfish to "sleep" until the normal time control for the time control which was selected is met. It's a non busy sleep and will not use your CPU while Stockfish is sleeping. The ladder settings allows Stockfish to play at a range estimated ELO from 1200 to 2600. It slowly increments the number of positions Stock\fish will see, the positions increase every 25 ELO roughly 19% , effectively doubling the nodes for 100 ELO. If one starts at the bottom of the ladder, Sf would play at a near 1200 level. At Ladder level 1250, , it will look at ~ 19% more positions. Level 1300. would see double the positions. There are 57 different playing levels , starting with 1200, 1225 1250 etc., ...all the way up to 2600.

The Ladder Delay function also works as toggle,when it's your move, you can toggle the delay off or on, so if you think the move is an obvious recapture, you can toggle it off and on the next turn, toggle it back on.

With Ladder setting 1200 and skill level set to 3, you can get a very weakened Crazy House Stockfish - ideal for those new to Crazy House

Thank you for doing this, much appreciated. All I need now is some kind soul to compile a Windows version , also a 32 bit if possible.

Michael, please check out the LP code patch. It generates some (non-critical) warning from the compiler, perhaps you could clean them up and incorporate the patch in your code base? I didn't use it for the Variant bins since for some reason it made the POPCNT exec slower than vanilla old x64 (!); maybe you could figure out why it worked for SSE but not Variant.

just really learning Crazy House - this is my best game thus far , using the Ladder rating of 1200 - generally less than 100 nodes ,but keeping skill at 20 ( highest) - also no take backs here ;>). For now using no opening book.

Was in control at move 20, lost my way around move 40, but then came back.

ugh! just did some quick analysis - missed a mate in 2 and a mate in 1 , but like said I'm just getting used to crazyhouse . SF also had several chances to mate me, but due to the weak level, failed to see them.

Was in control at move 20, lost my way around move 40, but then came back.

Lost to level 1 then beat level 1 and level 2 :

Hi everyone

No doubt I am missing something obvious here but I cant get this crazyhouse version to work in my fritz gui ( I am still using a Fritz 12 gui ).

Presumably fritz ( 12 ) gui doesnt support crazy house ? or have I missed something. When using the stockfish varient in the GUI it just plays standard chess.

With regard to standard chess I have only played a few games but so far the ladder rating handicap levels seem to play very realistically, at least a lot better than some other handcapping methods. well done and thanks.
