thoughts?

edit to add more thoughts as per Meeloche's comment below:
note that his river bet is a shove for my 100bb stack.
re valuable reads, i have about 180 hands on him, i think he's 9-tabling, and so far he's seemed pretty standard. My guess is that he's a 6-max reg, we don't have history cos i don't play 6-max, and when i do i run into hands like his... This means that I'll be a relative unknown to him too, probably makes it even more likely that i have AAAA in his eyes. Dunno, aren't people less likely to bluff/value bet kinda thin vs unknowns in spots like these?
