Re: New Tool

Nice tool, but would like to request a scoring feature, using scoring rate percentage as points. So for example if score1 has 100cp and score2 has 80cp, we may use for example. def perf(cp): K = 0.7 # SF pr = 100*1/(1+10**(-K*cp/400)) return pr where K can be adjusted depending on the engine. for c...

Re: New Tool

Thanks Ferdy, I will give it a try, but isn't it more precise to involve the solution time in the formula? For example, running a set at 5000ms, an engine that finds the best move at 200ms (and is constant) should receive more points than an engine that finds the move at 4700ms. That is possible in...

Re: Retrograde analysis - TBs move sequences to checkmate

Hi, I am interested in finding the paths to checkmate given best possible play by both sides. Do you know about a good open source implementation of that? Ken Thompson's paper has a good description. Essentially it is a one-directional tree which is reconstructed working backwards starting from the...

Re: Engine match with python script

Just uploaded a basic script at https://github.com/fsmosca/combat There are some limitations such as no support for pgn file as start position, only epd file is supported so far. See limitations section in the readme. Thank you! It uses the python-chess modules. I think you should add a requirement...

Re: Engine match with python script

Hi, does exist a python script/program to let 2 engines play against each other and which creates the annotated pgn? Something like cutechess-cli, but written in python. Thanks Just uploaded a basic script at https://github.com/fsmosca/combat There are some limitations such as no support for pgn fi...

Re: New idea for a chess puzzle book, with two samples

I’ve always enjoyed the “what’s the next move” sorts of books. I do have some issues with them, though. First, they get you to focus on only one move, the “best” move. Second, there are not enough of them. :-) I came up with a three move quiz a few years ago, where you pick/rank your three best mov...

Re: Engines playing Musketeer Chess, good price

Isn't losing the gating piece when king is in check already punishment enough? That is the point one has to take the risk when planning to gate at king file. The advantage however is that one can have a centralized piece after a successful gating. What Daniel means is losing the piece because it wo...
