River bluff against BBuddy

[punter11235]

I have probably very tight image. MP2 is BBuddy.
I have two question about the hand (or other comment of course are welcome) what about turn push ? I am afraid he may be calling it with any A.
What about my river bluff ? Love it ? Hate it ? Standard ?
I hope to pushh him of any draw here and any A hand (good , bad ?)
