No this looks like a pinewood bluff to me .
But yeah this is fine asuming blinds are tight/nits or you have a huge edge on them postflop.
46o isnt really often in my button steal range but yeah raising the BTN folded to you can never be a huge mistake.
Also turn on auto reload and allways have 100BB .
Edit: Ninja editing OP so my post makes no sense is not cool .
This really belongs here http://www.cardschat.com/f50/ and u should include any reads/stats/history with op since it will get u alot better responses.
1) I like cbetting this flop since it dry, in general paired boards+cbet= instant profit at the micros
2) I like betting bigger on the turn, like .25.
3) I dont like the river bet size. What are u trying to fold out with this bet? If your bluffing
you want a better hand to fold(or in this case also to get villain of a Ace to avoid a chop). I just dont think a unknown(im asuming unknown since u didnt include and reads) 5nl players is folding a Ace here to a tiny bet and i doubt your getting him off 77+(or a 6/J).
So yeah im not really sure if i like betting the river and i defenatly dont like betting so tiny he looks us up with all aces.
