$.25/.50 FLHE 6-max: flop nuts, optimal line?

This hand came up after 27 hands at the table. Never played against the villain before so the HUD stats are only after 27 hands and therefore not really reliable.

I'm not sure if it is bad ettiquette to post with screen-names, but the html codes got ruined when I tried to change their names to villain etc.

My question is if I should save the 4-bet on the flop, with the hope of getting more action on the BB streets?

I feel I probably scared the villain to get defensive on the BB streets, but then again the flushdraw was out there so I did want to get most bets in before the next street. Should I worry about the FD in that situation or do you think it is unlikeley that someone would play a bare FD that agressive on the flop?

Could you just post the original hh so I could see bet sizes. Also are the stacks really that shallow for 50nl?

this is a 0.25/0.50 fixed limit 6-max hand

I think you did the right thing on the flop.

in limit you really have to make every raise that you can in order to get value. It's not like in no limit where you can just make one big move on one of the later streets to get your stack in. Every raise counts. Also, by making the pot bigger on the flop, you are giving your opponent better odds on the flop and turn, making it more likely for him to pay you off.

So I'd pretty much play it the same.

sorry i thought this was NL lol
