in the right situation (given images) i sometimes like to c/r the flop to portray more strength than tpwk is, though this beefs up the pot (which obv. isnt good here with a weak hand).

in this situation you want to keep the pot low. Hell if the flops 5+ way i'll sometimes even check fold tpwk.

BTW FWIW we pretty much all lose money with one pair, and only start making money with 2pair +
