If you want to create a winning poker bot you need these few things.

OCR software to recognise stack sizes, position on table, cards, antes, blinds etc, all the variables.

Then it needs to translate this into something legible so that this spot can now be looked up in a GTO database.

DB gives the answer, voila you have solved poker.

Where exactly does anyone play 8-max poker? I'll never understand why people solve for 8-max its so frustrating. Also antes at over 10%. Non poker players solving poker.

No, this has been solved already for all stack sizes, look up MonkerSolver.

Bots are detected using a number of different methods, probably last of which is how they actually play their cards. Bots have consistent timing tells on actions, they always click the mouse button on the exact same pixel, they fail captcha's etc.

Bots are not really an issue, the bigger issue is assisted play for a human. So a programme tells the player the optimal move and the player executes it. That's much harder to catch.

Poker is solved already bud don't waste your time
