 # Contributing
 When contributing to this repository, please first discuss the change you wish to make via the repository's issues.
 If you are wanting to tackle one of the pre-existing issues, please comment on that issue so that you can be assigned to it.
 Alternatively, just send a PR and I will check it asap. Please bear in mind that I may not be reactive if I was not expecting a PR.
 ## Guidelines
 - We use the [GitHub Flow](https://www.gitkraken.com/learn/git/best-practices/git-branch-strategy#github-flow-considerations) branching strategy. Add your code into a feature branch such as `feature/feature-name`.
 - Write good commit messages. 'Fix bug' is not a good commit message. 'Fix bug with comments before moves' is a good commit message.
 - Explain the changes in the PR comments

 1. g4 { This is where white has to make a decision between 2.Bg2 (the tactical Grob) or 2.h3 (the positional Grob). Bishop g2 is the move which will be presented through out this course, for the desire is to gambit the g4 in order to distract blacks queens bishop from the defence of the queenside. Moves c4 Qb3 is the general plan. Where as h3 will lead to its own type of game, known as the positional Grob. Too which, I would highly recommond U Cannot Be Serious! by Basman & Welling, and The Killer Grob by Basman.
