Okay, one dose of brutal honesty coming. I'm pretty good at providing that so let's see what you've got here:
(Edit- This post is freaking long. I read through and typed my thoughts as the hands played out. If my thought process gets broken or difficult to understand point it out and I'll explain better)
First thing, why aren't you topped up? Always have the table maximum, or at least 100bb, whatever you're comfortable with. Personally I always have at least the maximum because I want to make sure if the right hand comes up I can take the most money possible from every player.
*********************************************************
Hand 1)
Raise larger
You should be raising to 3.5-4bb + 1bb per limper (3.5+1 per limper = Bet Pot Button; Live games or no Bet Pot button go with 4bb+1) So here I'd like to see you make it $0.50
That could have helped avoid the massive multiway action which makes things harder. So now BB donks into us for 1/2 pot. He could have played something like 67 getting great odds or could have a random Q, set, maybe just a draw.
I don't hate the call, but then the CO flats behind...that's setting off spidey senses.
Terrible card for our hand turns and BB pots it, I'm done with the hand. I see you call here, I'm crying inside. One other hand squarely in the BB's range (KQ) just pulled ahead of you, as well as any Kx holding he was just bluffing the flop with. Not a draw heavy flop so I'm done at this point.
Turn is the 8, so 45 gets there and villain puts us all in. I honestly don't know what he could hold that we beat, I have to say fold here.
Okay so he did have the 67. I think a larger preflop raise could help get some folds there, but he may elect to play it anyway, and that's fine. Just make sure we're charging him to do so. But where this hand really goes off track is the turn call. Villain donks into us, this can have different meanings for different players, but in general this is more frequently a sign of strength. You do call, as well as another player, however the BB pots the turn. At this point villain should not be bluffing. He got called in two positions, he made this bet expecting (or hoping for the call). This bet sequence really causes me to narrow his range to very strong holdings, and we have to walk away.
*********************************************************
Hand 2)
Depending on villain, I'm going to 3bet this a lot. CO ranges, even among tight players, generally get a bit looser and AQ should have strong hand value against their CO opening range. If 3betting oop I prefer to go to ~4.5x their bet, in position I'll 3b ~3.5x.
So you check, the blind bets 1/4 pot, preflop raiser flats, then you min-raise...I don't mind the raise here. A min-raise preflop leaves lots of random holdings, so there could be 87, 89, 8T, 23, 24, 25 out there which leaves our position unsure with quite a few turn cards. Therefore taking the pot down while we likely have the best hand is fine. However, the min-raise is unlikely to do that. I would prefer you put in a solid raise here around pot. A pot-sized raise includes the amount your would call. Here the pot is $0.80 + $0.20 from CO and BB = $1.20 (Your $0.20 makes the pot $1.40 so a pot-sized raise would be $1.60). That's what I'd like to see, $1.60 to go. Instead we min-raise and of course get two calls, at least more money in the pot right?
Okay, turn peels an 8, that kind of sucks. I would bet/fold this street. Even though a min-raise, we raised the flop. Maintain the image, and bet out here. If you meet resistance give up. The CO bets 1/2 pot, and I'm a little conflicted. I think this might be a great place for a reverse blocker bet. If you check/raise to something like $3 here and he comes over the top, it's an easy fold. If instead he folds, that's fine too. If he flats, then we're check/folding the river because we expect the hands we beat to be afraid of betting again on the river after getting c/r'd on the turn. This saves us some money with a holding as such, because if he has us beat, but we just check/call two streets we don't know how much it's going to cost us. We played passively and may have the best hand, then again we could be beat, we just don't know. By raising the turn we set the maximum we're willing to commit for logical reasons, and can continue the hand with a plan.
River is a brick, we check, and he bets just over 1/2 pot. I don't think we can fold here, because there are several Qx hands we beat but he could think he's value-betting, so I'm fine with the call. And villain has one of the 8x holdings. Well one good thing is this illustrates my last point of the blocker bet. Had we raised to $3, we would have saved ourselves $0.66 on the hand. I won't type it all out, but think about it. Pretend your in his spot and you hold QJ, QK, T8, how do you react when you get c/r'd on the turn? Then apply that to our side of the hand here.
*********************************************************
Hand 3)
Same as before, top off and 4bb raise + 1bb per limper
I would have played the flop the same! Actually I would have played this whole hand the same. Playing with effective stacks of 47bb and you flop TPTK. At the flop Pot = $1.20 and remaining stacks are $4.44. This is a fine spot to commit with TPTK.
On the turn Pot is $2.80 with $3.64 behind, I like the bet size. 1/2 pot allows those weaker Tx's to come along and sets up another small river bet that commits his stack. He shows up with a better hand this time, moving on
*********************************************************
Hand 4)
I'm wondering what's affecting your flop cbet size. Last hand you bet $0.80 into $1.20 (2/3 pot) on a dry board with TPTK. This hand you bet 1/2 pot on a dry board. I like to stick to cbets of at least 2/3 pot. You're betting because you either want to take the money that's in the middle now or get a worse hand to call. If villain has a hand that he's calling with, he's probably around the same probability to call a 2/3, 3/4, or even pot as he is the 1/2. So do yourself a favor and bet a little more when it's for value.
Turn is a Jack of spades, makes the straight for 89, and puts basically every single other hand with a king in it ahead of us. Notice that now KT, KJ, and AK all are ahead of us, not great. A ten might have called a flop bet, but probably can't stand up to the two overcards on the board plus a double barrel. At this point I don't see a hand worse than ours that will call a bet here, so I say check. Instead hero bets 1/2 pot and MP calls. At this point he's either drawing, or we're behind. The 89 draw made it on the turn, JQ is possible but one Jack is on the board and one Queen in our hand, so unlikely...not seeing many draws, so when he finds a call on our turn bet that's probably not good.
River doesn't really change anything. We go from one to two pair, but KT made the boat, KJ still has better two pair, and AK has same two pair and outkicks us. Also if villain did somehow peel two barrels with a naked Ten, well he just got there. I would check and probably check/fold. Hero 1/2 pots and....oh that sucks he got there on the river. That was my least likely expected hand for him, however the bright side is I'd make a note that villain called 2 1/2pot barrels even when a 2nd overcard hit on the turn and look to exploit later by value betting top pair holdings for three streets.
*********************************************************
Hand 5)
Did you hear me or something? Great job raising a more proper size, you're already improving! Notice how this raise isolated to a heads up pot immediately. Not saying it's solely because you raise a bit larger, but that helps I promise!
Aw, you let me down on the flop. You took the initiative preflop, maintain it. 94J rainbow is fairly devoid of draws, one broadway card on there, great time to cbet 2/3 pot ($0.60) and end the hand probably about 1/2 the time.
Turn spikes our Q, nice. And villain now donks for less than 1/2 pot...less happy about that. I'm flatting here hoping that he's betting a Jack or 9 and hoping my ace high will call his small bet. If I raise now I blow him off these holdings that pay me and leave the things like T8, J9, JQ, 99, 44, JJ, QQ.
Hero instead min-raises, and gets 3bet. Well at least now we got our answer, this is a fold. Unfortunately that message didn't get across and Hero flats, there's nothing good that can happen after this. If he was playing one of those weaker hands we beat, he should have given up even after the min-raise. When he sticks in a 3bet on top of it we have to let it go. This is similar to a Baluga Theorum spot at this point in the hand. I feel like this call here is not based on logic other than "I have TPTK and I think that's better than whatever junk villain has". A line of thinking similar to what I'd typed above as I was reading the hand will lead you to clearer thinking at the table.
I don't know what happens on the river yet, but I'd be quite willing to guess it goes villain bets, Hero calls, villain shows T8 or KT. Yeah, there it is.
*********************************************************
Okay, so my #1 suggestion for you is to really start working on thinking about the other player's holding. It seems like right now you're playing level 1 poker, where you hand has an absolute value in a vacuum.
This is an extremely common thing, especially at uNL. The tendency is to think the other players are all awful, and will call down three streets with any piece of the board. This may have been true in the past, but not really anymore. Players in general are better, and play more soundly than in the past.
Try and understand what ranges people can be on, and how your betting or decision to check can alter that range and what portions the villain will be able to continue in the hand with. This will go a long way towards making better decisions at the table.
