well nice experiement.. but i think the last hand is kind of biased.. he had top 2 pair.. A 10.. on a really nice board too.. theres only one possible straight out there which someone holding 79 would have.. but he probably has u figured that u arent going to be calling with the 79 on the flop and turn.. so the only hands that beat him are a set... most players here would call ur all in river raise with the top 2 pair on a board like that, especially at 0.05/0.10c games. but if he had a marginal hand lets say A4, A7 or A9.. or any ace with a shit kicker and he called that river-raise.. then maybe, ur table image experiment worked.. but that would be another story right??
