Thanks for the reply Veriz. I'll get started with the next homework on Monday 
A brief pre-session look at two marked HH's from last month!
This is something I am now trying to do before most of my sessions. Very simply looks through two marked hands from last month and estimate in "vague" hand groupings (as I should in game) a villains range, and also estimate my own perceived range.
Well, lets go!
Hand 1
In this hand villain is a 45/8 player on 231 hands. He has 2.3% 3bet, 60%(15) f2cbet, 1/3 fold to turn barrel so far and roughly 45% flop aggression, 30% aggression on turn and river.

BB: $4.98
UTG: $5.30
MP: $5.00
CO: $7.92
Hero (BTN): $5.14
SB: $11.98
Pre Flop: ($0.07) Hero is BTN with K
9 
3 folds, Hero raises to $0.12, SB calls $0.10, 1 fold
I open BU to standard steal size villain calls. All sorts of Ax, Broadway combos, pairs Suited connectors and the occasional slow-played monster.
If he is capable of hand-reading at all he should think I'm raising a lot here preflop (my BU steal is 45%) and I have tons of Ax, suited Kings, broadways, connecters etc.
Flop: ($0.29) J

SB checks, Hero checks
I am surprised to see I check here, Its probably going to be a meta-game thing with me cbetting a lot or seeing he likes to call down Ahi or something. When I check rather than betting it will be invariably because I do not feel I will generate enough fold equity with a double barrel which is what I'm often going for when any
T, Q or 9 comes on turn.
My flop-check range will now look like something that has some showdown value, 3x 55, A6, OC+noheart. It is unlikely that I am slowplaying here.
Turn: ($0.29) Q
(2 players)
SB checks, Hero checks
Villain checks which makes me think he is either trapping, has mediocre showdown value, lowpair or Ahi or he wants to C/R with a draw. The other possibility is that he has read my flopcheck as a value-hand that won't fold to a turnbet and is giving up.
This turn should be a good bluff-card for me and I have a gut-shot to go with it. Even after missing flopcbet I should be able to take down the pot easily enough to justify my bet versus his weak showdown to giving up range.
Again meta-game active table image or something is probably the reason for my check. I either think I have not enough fold-equity, suspect a trap, or believe I can showdown my Khi to win the pot.
River: ($0.29) T
(2 players)
SB bets $0.14, Hero raises to $0.40, SB calls $0.26
On river villain bets and I put his range as being some slowpayed Jx or FH, Qx or a Tx that hit river. There is almost no AK in his range, I block K9, and there is no so much 89 either. I feel weak Qx, Tx or underpair is the majority of his range so can throw in a small raise.
My river raise looks slightly retarded as I have about the only hand that would do it. I'd cbet TT, AK QT Jx 33 etc and its also very unlikely that I wouldn't have bet this hand on flop or turn. I think its understandable for villain to call QT Tx or Qx here.
Hand 2
BU is 25/14 on 454 hands with 29% BU steal, 62% foldto3bet (1/2 on BU). 54% fold to cbet 35% agg freq flop, 29% turn, 23% river.

I assume BU steals Ax, all PP's, all broadways all SC's, 75s+ and maybe K9s or something.
My normal play is to 3bet, I have no Idea why I didn't. I think that's a mistake and can't really think of a meta-game reason why it isn't. He has 0/13 4bet.... Maybe I just didn't like have AQo instead of AQs?
As played my hand looks like one or two Axs I didn't 3bet pre, some broadways, no traps, mid-pp's, and some SC's.
Flop: ($0.45) 5

Hero checks, BB checks, BTN bets $0.30, Hero calls $0.30, BB folds
Villain bets a large majority of his range from decent Ax through to FD's, Sets, broadway+backdoor, two-pair, underpairs. Vs two players he may check weak Ax and some lower pairs.
when I c/c I probably look like some Ax, passively played SD or weak FD/ FD+pair. My C/R flop is 5% and raise cbet is 10% thats probably a bit low really so apart from sets and strong FD's villain likely can't knock much out of my range here.
Turn: ($1.05) J
(2 players)
Hero checks, BTN bets $1.00, Hero calls $1
Villain makes a polarising potsize bet. Very strong draw, made hand or big bluff. Options include 55, 77, AJ, AKc, KcT, KcQ and then random cards he's decided to go crazy with.
When I c/c I still look like I could have a potential drawing hand, but also AQ AT A9, scared passively played 2-pair. Set, Flush are starting to seem more unlikely.
River: ($3.05) 2
(2 players)
Hero checks, BTN bets $1.45, Hero folds
I look like I'm trying to get to showdown with weak-ish Ax or have missed and given up with a draw.
Villain makes what looks like a clear valuebet 1/2pot vs the check to try and extract value from my AQ AT A9. I think the weakest he might bet here is AK, and his range then goes up to two-pairs flushes and sets.
Conclusion;
Wow, it took a lot longer writing that out than I thought it would but there is an example of what I try and do before a session. Regarding my play in those hands I'm not sure it was the best. It seemed to me in the first hand I would have had a higher ev betting on flop or turn and in the second I put myself in a horrible situation by not 3betting preflop and let the opponent put me to a decision rather than putting him to one.
Comments are obviously appreciated along with suggestions on how I can refine this pre-session warm-up to think about max-ev lines while in game. In-game being the operative words.
Good luck at the tables yall
