Really good for learning lines, and the flexability it gives is extremely nice. It allows you to easily learn your preferred lines for any scenario.

Not bad, but would be far better if it caught transpositions. The people saying "just go to chess.com" are obviously unaware that chess.com sucks. They *meant* to type "go to lichess.org" which offers all the same features without a paywall.* You're welcome. [*Although I *am* voluntarily a lichess paying patron because I was able to do unlimited trainings even before I paid them, unlike chess.com which gives you a "generous" five training problems a day before the paywall.]

"Chess Opening Repertoire Builder" is barely a game, it's more of a Chess tutorial (game adjacent, I guess) that, while it might help you with Chess openings, seems to be more of an advertisement for the developers $20 Chess game on Steam. Now, you can play Chess for free, so I have a few issues with people trying to charge money for it on Steam... it seems to be a bit of a waste of people's time. And that's not just me, gamers rejected this on Steam (player counts below). What do you do in the game? Not much in the way of gameplay... this is more of a software app that explores various Chess decision trees. But opening game only... imagine putting a Chess game on Steam you can't even play Chess on. $20 for the full product. For gameplay purposes, because the user interface for this game is mostly just 2D static text/images... it might as well be a web page. It's functionally no different from a browser game. And we all know, Steam isn't here to compete with Chrome and Firefox. If the game can be done in a web browser, it's just not rich or compelling enough to appeal to serious gamers on PC. The game features really lacklustre 2D visuals (does the developer not know 3D…

Sharpen Your Chess Arsenal (But Maybe Pack a Lunch) Chess Opening Repertoire Builder isn't your typical chess game. It's a training tool specifically designed to help you build and solidify your opening repertoire – the foundation of any successful chess strategy. While it might not have the bells and whistles of some full-fledged chess engines, it offers a focused and effective approach to mastering those crucial first moves. **Building a Repertoire, Brick by Brick** The core strength of Chess Opening Repertoire Builder lies in its structure. You can choose from a variety of popular opening lines, then delve into detailed variations and key positions. The program provides clear explanations of strategic concepts and tactical motifs, helping you understand not just the moves, but the reasoning behind them. It's like having a personal chess coach guiding you through the intricacies of opening theory. **AI Opponent: A Practice Partner, Not a Grandmaster** The built-in AI opponent allows you to test your newly acquired knowledge against a digital sparring partner. While the AI's strength is adjustable, it's important to remember that it's not here to replace human competition. It'…
