Did i get out of line ???

[sharpeyez]

I have KQo in early position 4 handed...
The blinds are .25 .50 and i make it 2.50 to go....At this point i would say i have a pretty tight image i have only shown down big hands. He calls out of the big blind. The flop comes down J 7 5... suits are unimportant. He checks and i bet 3. He calls and the turn comes another 7. I bet 7 this time. and he just calls again. the river comes a 10 and i had smelled weakness the whole time and bet 15. he goes into the tank and thinks....results to follow

Note: i have been making big bets on the river with big hands
