100NL

Btn hasnt done anything i wouldnt expect from a 100nl. Made a transparent bluff when a scare card hit at which point i pushed and showed him i could read him. But this was close.
Important factor i thought was his range which is why i had to think, for once i didnt think this was a no brainer with effective stacks.

(6 max table cant find the hh so apologies)
Btn $350
Miffed (bb) $390

Dealt to Miffed
Btn raises to $2
Miffed reraises $10
Btn raises to $25.
(miffed thinks damn hard then calls)

Flop :Ks: (pot $50~)
Miffed bets $35
btn pushes the the lot
Miffed thinks even harder and calls...
What do you think?
