Senpai 2.0

[hagtorp]

Thanks Fabien.

Hi Tony,

Unfortunately, none your compiles, 32-bit ot 64-bit, work on my systems (of course I used your dll's) :
*old laptop, Win 7
*old biprocessor, Win XP w32 and Win XP x64

The command uci works, but the command go depth 16 (or other) leads to a crash ("Senpai 2.0 encountered a problem...").

In 2014, there was a guy here named kongsian who produced a Senpai1.0_32.exe compile, which was the only one working with my systems.
I sent him a p.m.

Have you tried it in a GUI too? Several uci programs don't run with
a 'go' command in the console, but still work in a GUI.
Senpai 2.0-64 does the same here on my hardware.

It worked for me from the console when I issued an isready command before the go infinite command.

You're right. Senpai 2 needs a "isready" command before a "go" command

Well, ladida!, thanks Tony, Guenther, Steve !!!

Indeed isready is the password for Senpai !!!

Fabien, salut !, tu aurais pu le dire !!!

Note that this will work also for others you thought they don't work.
Regrettably I don't remember which ones they were.

Thank you Fabien. The source code is absolutely beautiful. I always enjoy your work. It is like art.

Thanks!

The code is actually subpar compared to, say, version 1. The simplicity is now between the lines, in eval for instance.

Senpai could really benefit from at least 5-men TB support. In a game from a recent 40/4 4CPU CCRL gauntlet it reached the following position against Fritz 16:

[d]8/8/k3b3/3p4/2pK4/8/8/3B4 w - - 0 159

This is a 6-men TB draw, and the only move to draw is 159.Kc5. Senpai played it and found several other only-moves until here

[d]8/5bk1/8/3p4/B1pK4/8/8/8 w - - 0 177

where after a 17-seconds think it blundered with 177.Bc6 (177.Ke5 was the only move) and F16, using 5-men Nalimov, naturally didn't let the win slip away.
