Tarrasch V3.10c

November 4, 2018

I have been using Tarrasch V3.10 extensively since its release for my work on the New Zealand Chess Magazine. Yesterday I decided there was one issue I had encountered that required an immediate fix. In the cruel way these things often work out, a second such issue popped up today, less than 24 hours after publishing the previous fix. I decided to take a deep breath and just make another release. Sorry.

For the record – the problem fixed today appeared if you started a second instance of Tarrasch and then tried to use the database. Multiple instance Tarrasch is much improved with V3.10 – now when you use Windows explorer to load PGN files they will load into an instance of Tarrasch that’s already running rather than start a new instance. But you can start multiple Tarrasch instances if you want to. And helpfully if you do that, the second (and third etc.) instances won’t all load the database into memory. So multiple instances of Tarrasch don’t waste vast amounts of memory unnecessarily. But then if you do try to use the database you get a helpful message telling you how to force a database load. Sadly (so sadly) if you actually followed that advice Tarrasch would crash (a NULL pointer bug as it happens). This bug now fixed with Tarrasch V3.10c.

    Hi! Love Tarrasch, it’s amazingly useful. Thank you, thank you, thank you!

    I have only ONE minor gripe: all boards are oriented (which color is on bottom) the same way. Since one plays each color on roughly half of all games, it would work far better IMHO for the board orientation to be specific to each tab. Hopefully that’s an easy change to make!

      That’s an interesting one, I don’t think anyone has ever made that suggestion before – and I certainly have never thought of it myself. In my own personal use I rarely (never?) have a bunch of my own games in tabs, which is probably why I never considered it. It probably would be pretty easy to do, I will look at it next time I update Tarrasch, hopefully before the end of 2018.

    Will this GUI work with the new era of chess engines such as Komodo MC that operate using MCTS tech pioneered by Lc0 and AlphaZero?

      I don’t see why not. These new approaches are all about the internal implementation of the engine. As long as the engine is still setup and controlled by the UCI protocol, the engine will work inside Tarrasch
