    Gtobase cool thing. You can fill in your hand base in it and see where exactly you are most mistaken. Due to the fact that it already has a pack of high-quality calculations with subsequent lines that are different across all the streets, identifying one's own mistakes is almost instantaneous.

    GTObase is a convenient, multi-functional software that greatly simplifies the work on the game and the analysis of played sessions. What could be easier than after the session, upload it to the site, wait 5 minutes and see the biggest EV errors. Or mark a few hands and view them after the session

  • Jay

    I was very excited to see SimplePoker's new tool GTOBase. I've tried other tools that promised so much, but there were always too many bugs and random crashes. I've uploaded many hands and had GTOBase do the analysis, and there's never been a single crash. The hand upload is amazing - it's super fast and the results are easily interpreted
