limper raise flops pair + flush draw IP

Fold preflop > Call preflop >>>>>>>>>>>>&g t;> reraise preflop, unless you have a read which you did not mention.
On this particular flop you should be 2/3rding it. So 1k is a MUCH better bet.
Turn fine check behind because you are never stealing this pot because you have played this hand entirely too weakly so far.
River is bleh, given the way you have played so far, flat calling almost has to be better.

Fold pre... as played, call, KQ got there, and a million other hands that beat you.

I agree that folding river is probably best, but flat calling is better than reraising, if OP must get to showdown.
