Exploiting Fish Mistake #3: Bet-sizing Errors

[bigspenda73]

Mistakes which fall into this category:

-Failure to protect a vulnerable hand on draw-heavy boards
-Failure to build big pots with strong made hands
-Slowplaying in incorrect situations
-Bet-sizing tells (small flop leads, large overbet shoves, etc...)

Some exploitations may seem simple/easy to you however it is best if we list them all. Let's hear about ways to exploit these mistakes!

Failure to protect on a draw heavy board:
Most often I see fishes here flop TP but see the flush draw and think "man, they're gonna suck out on me" and they bet weak, let's say $0.25 into a $1.50 pot. Calling down is the easiest way to exploit here.

Failure to build big pots with strong made hands (i.e. slowplay):
You actually don't have to do much to exploit this....they do it themselves by not charging you as much money as they should to see later streets. This is very closely related to not protecting on a drawy board. They often go hand in hand.

Bet-sizing tells:
The biggest one I see at this level is check raising the flop. More often than not, this means two pair or better, and I can fold. If they would have just bet out for 1/2 to 2/3 pot, I would have called with TP and they could build a bigger pot.

Overall, I feel these mistakes are the easiest to exploit because they beg you to play your hand correctly.

If they fail to protect their hands, I'll peel and stack them when I hit. If they fail to build big pots with strong hands, I can easily just get away with putting in very little money with my marginal hand. I mean, I usually call a river bet and find out they've butchered the hand completely when I would have called a bigger bet or even two bets instead of one. In terms of slowplaying, if they don't lose the pot due to it, they'll lose value.

I see a small flop donk as a clear sign that I need to raise the donk. It's profitable to do this ATC because I see donk/fold a lot. Large overbet shoves have a propensity to be bluffs and nut hands. So don't think that your medium strength hand is good against his value range. Any hand you have becomes a bluff catcher unless you also have a nut hand.

A good bet sizing tell is when fish min 3b / min 4b / min 5b you. This polarizes their range to big pairs and crap. But the more passive your opponent is, the more you can assume a huge hand. It's OK to setmine with QQ sometimes, when your fishy opponent just min3b you when he has a 0% 3b over 200 hands. You definitely don't want to 4b and basically turn your hand into a bluff.

Another bet sizing tell is when someone bets small on the river with a scary board. They're betting small because they either know that they get a fold even betting small or they have a good, but not great hand they want to get super thin value from. For example, if someone bets 1/3 pot on the river IP on a 4 straight board, they usually don't have the straight but want to get value from their hand or they are bluffing. To exploit either one you can just check-raise big if you think a hand like top pair is folding to a large raise on that board.

Failure to protect a vulnerable hand on draw-heavy boards
-Since they are giving us very good odds to draw-we just flatcall
-Valuetown thin when we hit our draws

Failure to build big pots with strong made hands
-We get to see a Cheap showdown value which is good.Calling would be just as good here.
-Never raise their decent size bet

Slowplaying in incorrect situations
-Fish would love to C/R the turn a lot.
-B/F is the best to exploit this.

Bet-sizing tells (small flop leads, large overbet shoves, etc...)
-Yet again.B/F seems to counter large when we are not sure we are behind or not.
-Raise when we sense small flop leads-weakness
-Fold/Call when we sense strength

Another thing i would like to mention is a huge huge 3bet sizing
i.e Hero opens 4xbb,Villain repops to 20xbb

Disappointed in the replies so far

Think people, don't just say the first thing that comes to mind.

Talk to me about ranges, equity, manipulation.

I will unlock these threads later, for the time being think outside the box a little bit, jot down your thoughts, and we'll enter them at a later time.

Now that everyone has had some time to think, perhaps we can come up with some creative replies. Things I am looking for:

-example HH's with reads
-ranges and pokerstove calculations
-pot odds calculations
-anything else that might make someone actually think

Basically I'm looking for some evidence that you sat down for more than a mere 2 minutes and actually put a lot of effort into determining methods of exploitation.
