Looking to improve my poker game against tough opponents. Are there any AI bots that can simulate real players and help with training? Need something challenging but not impossible.

Yes, there are some good artificial intelligence poker coaches out there. One platform creates really realistic scenarios, for example. It adjusts to your skill level and even simulates different types of players. The best part is that it explains why it makes certain moves, which helps you learn. You can try it out at this site: http://aifarm-bots.com/. This kind of training against poker bots really teaches you a lot of strategies.
