That’s actually a very valid concern, and I had the same doubts before trying anything myself. From what I’ve seen, the key difference is how you use the tools. If you’re using something like a GTO Solver strictly for post-session analysis or studying away from the tables, it’s generally considered safe and similar to reviewing hand histories manually. That’s how I’ve been using it — going over tricky spots after I’m done playing. Problems usually start when people try to automate decisions in real time, which many poker rooms clearly prohibit. So as long as you stick to learning and analysis, you’re on much safer ground.
