With no draws on the board a call can be far more intimidating to a solid LAG who will be cautious of gettng trapped, if he comes out fireing again then he is confident in his hand.
This is true, so Im curious as to whether you are saying you would normally give the pot up unless you are checked to on the turn? Or having 'intimidated' with your smooth call, is there a case for repping trips by winding up a pot-sized raise to his turn bet, or would you think this is -EV knowing you have few outs and you are definately behind if he calls. At micro-limits certainly, if im the villain here I am among one of those 'fish' who has seen too many garbage showdowns to think I should fold my big pocket pair in this situation. At higher limits maybe theres a different mindset.
