TPTK vs possible river bluff

[kimjjjjj]

Only second hand played so no reads. The first hand I had raised and C-bet exactly the same way against the same player and taken it down without any fuss.

How terrible is it ?

stack sizes?

not terrible, my turn bet though would have been smaller, like $2.40-$2.50.

W/O reads, tough spot, I'd prob call...

Sry, forgot about stack sizes. I had 21$ and he had me covered.
