Semi-Tight Aggressive

Seems to be the new way to counter game theory optimal.

This seems good - all the articles I've seen online on advice talk about sticking to tight, aggressive play when you are learning the ropes - only become looser if you are very experienced. Usually the simplest plays are the best.

You don't understand what game theory optimal is if you think there is a counter.

My teacher says to play tight agressive too but I think that to be a player like this I need time to get experience.
