yeah first one is PROLLY alright, i mean i doubt he would be bluffing with tt here cause he still thinks he has value in it, so its either like a 5, maybe jj or a bluff. The only thing that worries me a little he he may be pushing here with 22-77 or something as what he thinks is a bluff. Its still prolly good tho.

The second one though i don't like, i agree you are going to be snapping off bluffs sometimes, but it is also very common for people to check an ace here, both strong and weak. I also think that in his range for "bluffing" he could hold some queens in his hand, so i really don't like this call.
