It was me, but was it really you?

I can't say for certain, as some of those guys change their names by the minute and a few might have been me for a minute or two!

Yes you did!

I found your explanation of the "top level" design of chess engines hillarious, so I decided to make it my signature.

I must have been really tired. There is no need to play_good_move since the move is already good. You should just call play_move(mv).

It made sense to me, at least, though if you wish to be really pedantic, then it should be find_best_move(pos), rather than a good one.

Good to see you back, it'll help liven this place up again.

Steve Maughan wrote:+ After an absence of a few years, what was the motivation for writing Senpai?
The clones wars were fading, so I needed to release some new strong open sources. Plus we need a new R[edited out by moderator]a 5.

Steve Maughan wrote:+ How long did it take you write Senpai?
A pair of hours in a six years span.

Steve Maughan wrote:+ Why did you start a new codebase? Why not continue with the development of Fruit?
Fruit is lame, it's only about 2800.

Steve Maughan wrote:+ Have you accomplished everything you set out to do with Senpai, or is this a work-in-progress?
The answer is contained in the name of the engine.

Steve Maughan wrote:+ LMR became popular after it was introduced in Fruit - is there any new "secret sauce" in Sanpai which you think may be of interest to other programmers?
There's a big hint hidden in the release readme !

Steve Maughan wrote:+ Why did you choose C++11 as the development language?
Trendy is funny.

*hiding*
Too bad there is no liking functionality.

+1!

A quick and informal test, but Senpai is clearly very strong:

Hi Fabien,

back from my work, jumping in TalkChess & CSS Forum for read the news of the year 2014

We have you back in computer chess and I think today in the evening we all can open a bottle of wine for different reasons.

It's all your own fault that so many others will be animated from your decision to start a new developement. You can be sure ...

But more important for myself is, that such a sympatic and pleasanter chess friend is back for myself. I lost last year a lot of persons I like but you gave me energy with your words and your work and of course all the mails we switched in the latest months.

Never I will forget it and now it's Senpai time for the next 10 years I hope. You will get some mails by myself again and of course with test results too.

Sorry, but to understand my bad English will be your problem for the next 10 years

Friendly
Frank
