The "little spades" part caught my eye here. Of the 9 unseen [img]/images/graemlins/spade.gif[/img]'s, two thirds of them are smaller than T. Even then there's still a 58% chance you're drawing dead if your opponent has 2 random [img]/images/graemlins/spade.gif[/img]'s.
Just for fun, here's a breakdown of the hands that beat us and the outs we have to win (not chop) weighted by their likelihood. Given the preflop and flop action, we'll rule out AA/KK/AK/K7/77.

Hand Ways Outs Weighted
A5 6 3+9 1.2
A7 6 3+9 1.2
K5 6 5+9 1.4
Ks5 3 5 0.25
55 3 8 0.45
XsYs 36 9*0.42 3.36

So, yeah, we have plenty of outs to see the river. Calling UI? I don't think so.
