You can't lead it to believe a point is an optimum, it's just responded to a bet size/check in isolation given the information it has. If you 'feign weakness' in a given spot it will just respond as optimally as possible to the bet size. For example attempting to feign weakness by betting small in a spot where your entire range should bet large is not tricking the AI, it's just passing up on EV for the players, good players are not going to play poorly in hope of tricking the bot for future mythical EV gain. Also, there is no 'colluding' in heads up poker.
