What is Vice?

Vice is a Video Instructional Chess Engine, written in C.

It was (is) written as part of the follow along series you YouTube by Bluefever Software.

Vice is deliberately simplified - the code structure is by no means to be considered best practice, rather a quick start into understanding the world of computer chesss engine programming.

Where can I get the binaries and what is the latest version?

You can find the download to the latest release (Vice 1.1) here:

I want to copy it, can I?

You can do whatever you want with the code. A lot of engines have been inspired by Vice - not all give credit. Probably it's better to give credit than not.

What are the main features?

Vice is simple, with the following features:

• Alpha beta search
• Iterative deepening
• Quiescence search
• Transposition table
  • Always replace
• Polyglot opening books
• MVV/LVA move ordering
• Basic evaluation

bugs to fix:

• The PickMove function needs a BestScore of -(very low) instead of 0
• Time management for x moves in x minutes causes losses
• ID loop needs to only exit when it has a legal move (i.e done depth 1 at least)

Who actually did this?

The real person behind the series is Richard Allbert.
