I bet 200 1 player calls

opponent instachecks i bet 450 he thinks and calls

river is some blank and he check eaven before river card has fallen.

he has about 700 left, but i decided to check for some reason.I later thought about it and i think i was missing some value.

My opponent is fairly straightforvard player have not seen him to do anything tricky.
