You bet $12
he raises to $55 ( and you have a hunch he's tryin to squeeze you out of your twelve.)
So, you put in another $43 to call plus $130 which is his stack size u say = $173 more into pot???
And you do this to "defend your $12" ??? Have I got this right???
How often do you have to be right here, just to break even???
to defend $12, you put in 14 times that much, "because you like your read here" .
Look at your hand. You have JT o.
Even villains get hands.

You asked me what is the worst I put him on. IMO I think your question entirely misses the point.
