Hi there dear mate, good to see you are into cash tables!
Well, first thing we have to consider is that we are opening many hands from the CO, varying from 15% to 30% hands/range or even more depending on the table/player/perceived range, etc.
When BTN calls, it also has a pretty fair range, also could be something between 20% and 40%, give or take.
One thing I have already discussed here with other players is the modern tendency for opening raises to be smaller, specially when we are in position, like Hero/You.
Because we are opening too many hands from these positions (CO and BTN), it is wise to choose a sizing that can fit for all of our range, and in the long run 3 blinds is a huge investment, far superior than investing just 2.5 blinds: consider that for every single hand you open IP with a sizing of 2.5 blinds (x), you are saving 0.5 blinds, so for every 200 hundred hands played IP we are saving 100 blinds, which is something to be looking for.
That more use in High stakes were the rake is lower,here u have to strait max from ur hand for compensating the rake.
But i do 2,5 only in BTN because is were you face more 3bets.
The postflop is a matter of the situation, but usually we can be c-betting or checking this flop in the same ratio (50% checking, 50% c-betting), and the size you used is perfect, because we can have many hands here and air and draws and the sizing takes into account all of these possibilities.
When BTN calls, it could have did it with Jx, 8x, even some 3x, although we are blocking A3hh, the flush draws and straight draws.
The Turn is good for both ranges, both players can have now hands like Q8, J8, Qx, Jx and the draws, and once we are blocking the flush nuts. OTT we can use many sizings, depending on what you want to do OTR: do you want to bet little OTT to put a bomb OTR?
Do you want to bet heavy OTT to shove all-in on many rivers? Well, considering we are blocking the nut flush, I would personally go for polarization here, charging specially from Two Pair, Sets and another Flushes or Flush Draws, and I would go for 100% pot or even more to put Villain all-in in almost 100% of rivers.
By betting so small we give the chance for Villain to realize its equity for a cheap price OTR, and this is not so good for us.
I don't understand your bet sizing OTR. When you bet so small a sizing like this it seems that either you have the flush and wants to be paid ASAP or that you have some strong second hand such as TPTK, Two Pair or Sets and got scared of the flush but even so wanted to extract thin value from worst hands OTR: by betting so little Villain can easily call with a lot of hands that have us beat such as lower flushes, Two Pair and Sets, but Villain elects to re-raise, where it shouldn't be raising, basically, never.
That zizing is a mater off strategie(the one i made), but the idea is to, is i bet big i wonth get value from bluffes or medium hands,only call the stronguest hands off his rangue, so i dont wath to let him check back with a medium hand, basically i let him bluff me and i guet value from weeker hands.
Villain should never be raising here because it is trying to represent the nut flush on which we are blocking.
I am only putting up a shove right here if I know my opponent is a reasonable, decent player, at least. Many regulars are not folding lower flushes or sets in situations like this so when we do go all-in with TPTK + Missed FD, it is awesome, good and fine, but this is move that relies entirely on who you are playing with.
Coming back to the subject I started on the turn, this is why we should go for heavier bets OTT if our plan is to go all-in on many rivers, because for the times we really do own the nut flush, or hit the nut flush OTR, it would be impossible for Villain to fold the vast majority of its range, because of the SPR: when we bet more OTT we commit both ourselves and Villain much more than simplying going for a small bet:
A smart player would be calling you down 100% of times, OTR, even with KQ for example, when you go for such lower bets OTT and OTR. By doing this you are giving free information for experient players, which was not the case: which hands raise OTR and fold to a push??? Why Villain raised anyway if it believed it had the best holding?
And believe me, Villain would have much more QJ, J8, Q8, 86, 33 and 66 than us/Hero, so..:evil:
