Quick post on flop bet sizing (do some research and there is much said about it).
It is not bad to standardize your bet size, rather than vary them by hand strength.
It is acceptable (and to many recommended) to vary flop bet size based on flop texture.
One of the arguments for varying the bet size is this: If I have a kind of hand and you have a kind of hand and I'm ahead - how many outs do you have? The flop texture defines what kinds of made hands and draws we can have and gives an idea how many outs we need to price out when we make a bet, and if we are observant we can make a bet size that makes it a mistake for many likely hands to call - while still making it tempting for them to call.
If the flop is very dry (three different suits, few/no straights possible, not too much high card emphasis as most ppl prefer playing high cards) the classical example is that both have a pair, I have the higher pair, or we have the same pair and I have a higher kicker - which means that the opponent has two or three outs twice to win. Even a half pot bet on a dry flop correctly prices out the hands you are most likely to be playing against.
Similarly the wettest flops will have a classical example of you on top/over pair and the opponent on a straight, flush or combo draw with 8, 9, 12 or 15 outs. In the case of 12 or 15 outs the opponent is AI and there's nothing really to do about it, in the case of 8 or 9 outs you pretty much have to bet pot to price out the draws.
A possible guideline is this:
3 different suits, no straight draws possible: 1/2 PSB
3 different suits, straight draws possible: 2/3/PSB
2 suits, no straight draws: 3/4 PSB
2 suits, straight draws possible: PSB
This should be a starting point and many comments are based on this - like in hand 2 a 1/2 PSB seems sensible as you may keep in 99-77 that might fold to your 2/3 PSB, which is why some comments have been to bet a bit less in hand 2. Because the flop is as wet as it gets in hand 3 that's a prime candidate for a full pot sized bet.
The point about it being a starting point is that after having set a standard bet size vs an unknown we should adjust it based on the playing tendencies of the opponent.
You may decide to bet a flop for value or as a bluff, but once you've decided you don't want your opponent to know whether you are betting as a bluff or for value and using the same bet size helps achieve this objective.
Imo, go back to hand 2 and state exactly which hands (aside from the TT that you happened to have in this hand) you would play in exactly the same way (with exactly the same bet sizes).
Example with a tight range (hand combinations in parenthesis):
Preflop: 22-AA, AK-AQ, AJs, KQs
Flop: 33 (3), 66 (3), TT (3), JJ-AA (6*4=24), AK (16)
Ok, I'll stop at AK this time to explain my point. Let's say we compare a PSB and a 1/2 PSB. If we bet 33,66,TT, JJ-AA we are betting for value - we think we have the best hand and if called expect still to have the best hand. If we bet AK we bet as a (semi-)bluff. True, if an A or K comes on turn or river we may improve to the best hand, but we expect to be behind. We bet because we expect our opponent to 1) call worse or 2) fold better (77-99 etc) often enough that it's profitable to bet some hands that don't beat a calling range.
If we bet full PSB a lot of the weaker hands will simply give up and fold. This will be especially true of 98,87,Tx,6x,77-99 hands that have some equity and might call a small bet. So with our AK type hands we fold some hands we beat and fold some hands that beat us - but with our better hands we fold out a lot of hands that we beat. If we bet 1/2 PSB we might get calls from many of these and while AK is not a favourite against this whole sub range it still has equity. And so does AQ, AJs and KQs. Since the bet size is smaller we need a lot less fold equity for the bet to be profitable so it can be mathematically proven (which I don't intend to attempt) that if we make a big bet we have to make it with a narrow bluff/semi-bluff range whereas if we make a small bet (and it still has some fold equity) we can be correct to make it with a wider and weaker range.
If we make a 1/2 PSB on a very dry flop we might end up both getting more value out of our value range and more value out of our bluff/semi-bluff range if we compare to a 2/3, 3/4 or full PSB.
