From the small blind on a 1-2nl cash game, hero calls ($1) with Ax3x. About half the table has called so there is about $10 in the pot. Everyone checks on the flop and turn. The river is a 3x so now hero has Ax3x3x. Everyone checks. Hero gets surprised reactions for checking with the best hand. But it seems to me there were so many possible better hands but this was a table with some very loose players. Should I have bet on the river?
Edit: forgot to mention this was final table with 4 players. I don't recall the exact board, other than there were no 2s.
