Know When You Are Beat
I just wrote a long comment for a DC member blog, but it didn’t format correctly, so I’m putting it up here. You can find the original post on icehockeyplyr’s blog.
I would like to preface this comment with the statement that this is obviously VERY level 1 thinking, but in vacuum versus an unknown player it will suffice for most beginning players.
One trick vs. “flopshovers†I find useful – especially on drier boards, is to work out how many legitimate hands they can have in their value shoving range. If you can count 12 combos that beat you then it is usually never a big mistake to fold and wait for a better spot when you have a medium strength hand.
There are some simple generalisations to this:
You will almost always be bet/folding TPTK and worse on a Q-high or lower flop. For example, 99 on 652r is a bet/fold. AJ on J76r is a bet/fold. KQ on QT7 is a bet/fold; however, KQ on Q44 is probably closer to a bet/call (count the combos yourself).
You will almost never be bet-folding AK on an A or K high flop unless the board contains 3 to a straight, or is monotone. It can easily be shown that it is in fact often correct to bet/fold on AKQ, AKJ and AKT versus some passive opponents who play any two broadway cards (they will very frequently only call with two-pair in this spot and will hold 16 combos for the straight alone, let alone the set combos).
bq. You will never be bet/folding two-pair or a set except on monotone boards, or when there is 3 to a straight (see AK hand above for an extreme example). You might also consider the strength of a hand like 87s versus a raise from a loose, passive opponent who is playing any two suited on a board such as Q87r.
You will never bet/fold AA except on KQJ and KQT.
Remember, these generalisations are very simple, and you will have to adjust your strategy in certain spots. It is often possible to narrow the range of hands for many villains based on preflop actions, and these can sway your decisions one way or another. However, if your opponent can legitimately have any set, AA, KK, and AJ+ in their range it is often correct to follow these guidelines.
One major caveat: If your opponent is frequently aggressive with drawing hands, or has shown himself to be a maniac and therefore warrant additional action, you will usually be making a small mistake by folding these medium strength hands. However, at the lower stakes where most players are passive and rake is your biggest enemy, occasionally folding the best hand is a much smaller mistake than calling off your stack versus a villain who is never ever putting money with worse.

good post. i like to apply this way of thinking to the turn more than the flop. i think stacking off with top pair good kicker is standard at 5nl. you see the majority wiling to raise/felt top pair without any regard for relative hand strength. they'll show up with pairs we have dominated a lot. if i open from co with kq and villain calls from bb then check-raises kxx or donk bets-3bets i get it in 100% readless. the majority of the time i see a worse k

I agree that in general you can't ever be making a big mistake felting TPTK+ at 5NL against a random opponent on most flops. However, I feel that this advice does have some merit, when readless. Against a large portion of the player pool: set-miners, weak-tights etc., it will be terrible to commit with just TPTK in this spot. To balance against this, you will get it in as a 55-60% favourite over the ranges of some bad/loose players.
However, to profit from calling off large all-in bets we must be defaulting to a general strategy that assumes a very large % of the player pool are exactly this type of bad/loose aggressive players, which in my experience is not the case.
To give some reference, AQ is a 37% dog versus the "wide" value shoving range of QQ+,77,55,AQs,KQs,75s,AQo,KQo on Q75r.

I think thats a bit narrow for 5nl. If we are the opener in a single raised pot @ 5nl then i think we can take qq out of villains range and add qj-q9. That completely turns the tables. On the other hand, if villain is opener, i think it will look something like QQ+,77,55,KQs,QJs,AQo,KQo,QJo. We are flipping against that range.

My intention was not to estimate reality, but rather to demonstrate that even when villain can shove a few worse hands we aren't even close to being an equity favourite. A beginning player might think that this seems like a great spot, when in reality it often isn't. Therefore, making the assumption that a random opponent is doing this is probably going to lead mostly to an increased standard deviation, not profit. Besides, I actually think that my range estimation is quite reasonable as a vast majority of opponents at the micros are just calling with TPWK hands.

Pretty nice post. But stubbered a bit, what boards do you mean when you say:
You will almost never be bet-folding AK on an A or K high flop unless the board contains "3 to a straight", or is monotone.
