When he donks pot (essentially) on the turn what exactly do you think he is doing this for? When a villain is doing really retarded stuff putting him on a range at every street is hard, for example it wouldn't be that ridiculous* to assume he's not calling Q4o pre-flop but against bad players we can gather a lot more information from active decisions like choosing to bet the turn as apposed to more passive decisions like clicking call.

If the software has it available you need to be making notes on this type of thing. Calling Q4o in the BB is awful & donking pot when he spikes two pair on the turn, of which neither card is the high card.

*Yet clearly wrong as shown by this hand.
