what would you do....

[Floundering]

I was playing in a tournament on PS against 19 people where 1st prize was a paid trip to Monte Carlo.
I think I was 5th out of 12 remaining when this happens:

Seat 2: 2 (820 in chips)
Seat 3: 3 (3090 in chips)
Seat 4: Villain (2605 in chips)
Seat 5: 5 (3130 in chips)
Seat 6: 6 (2070 in chips)
Seat 7: Hero (2660 in chips)
6: posts small blind 50
Hero: posts big blind 100
*** HOLE CARDS ***
Dealt to Hero [Ah Ks]
2: folds
3: folds
Villain: calls 100
5: folds
6: folds
Hero: raises 200 to 300
Villain: calls 200
*** FLOP *** [Jd Qs Jh]

What would you do? The next thrilling part of this hand will be forthcoming shortly...

I would raise to more like 400 or 500 preflop. I dont mind taking it down right now as we have to play out of position. That flop is pretty damn bad for you. Hands that would limp call include 67s-KQs. He could have picked up any number of draws, and I am probably just checking this flop. If he checks behind I will probably fire on the turn.

[Floundering]

Yeah, reasonable point. So, not only did I not raise enough preflop, I then went on to fire a continuation bet on the flop trying to take the pot then and there - trying to gauge his hand (or even better to take the pot if he missed).

Hero: bets 400
Villain: calls 400
*** TURN *** [Jd Qs Jh] [Td]

Now you would?

[Floundering]

that was a bit garbled. I meant I fired at the flop to either try and take the pot down OR to work out what he might have.

[Floundering]

Ok, so then I...
Hero: bets 800
Villain: calls 800

What would you put villain on now? Should I have gone all in (assuming 2 pair)?

[Floundering]

Alright, I can sense a lack of interest so I will finish off:

*** RIVER *** [Jd Qs Jh Td] [Js]

At this stage I know I am buggered.

Villain: bets 500
Hero: calls 500
*** SHOW DOWN ***
Villain: shows [Qc Kh] (a full house, Jacks full of Queens)
