I've not visited this site in over two years, have no idea how many of the "old guard" I knew still frequents this forum. Anyway....

Other than sporadically playing a little against AI on a CD-ROM poker game, and playing the EXTREMELY rare nano buy-in sng (usually NL) on Stars, I basically haven't played poker in ~4-5 years. So I'm sure there's a mountain of rust on my game; please help me look pretty again by going over some [probably very basic] HH's with me.

Last I posted here, proper posting etiquette was generally to post just a single hand to a thread, so that's what I'm going to do (even though some might be pretty basic, not a lot to delve into); sorry if I flood the page with 3 or 4 hh's in the next day or two.
Can't seem to get converter to work, but I'll try to make it readable....

Reads
CO: is pretty fishy. Posts early from any position when he arrives at a table, VPIP is probably ~45% or thereabouts. **Had yet to see him raise (in somewhere between 40-70 hands played with him); he once only cc'ed my HJ open on the CO with AKo.*** Does fishy things post-flop like donks flops when he's got something, just calling HU ip with tpwk on dry boards, etc.
SB: Not a terrible player--->Generally comes in for a raise when he's playing, have seen him iso reraise (though not sure if he does so consistently), probably not playing more than 35% of pots, consistently cbets flop HU, etc.

Poker Stars $0.05/$0.10 LHE 6M
Hero is on HJ with 99.
PF: MP folds. Hero raises to $0.10. CO raises to $0.15. BTN folds. SB caps to $0.20. BB folds. Hero....????

Assuming CO will call, I'm getting 5.5:1 on a call (not counting rake). Given above reads, what do you think?
pp's flop a set about 1/8 of the time, and it likely gets paid post-flop, though always the chance you flop a set and still lose [big] by the river. I seem to recall looking at ~5.5:1 as the rough benchmark pot odds to make set-mining reasonable, though maybe I mis-remember. Thanks in advance....

Easy call

call with any pocket pair here

Such a guy like CO can wake up randomly with beautiful hands like KJs or A10s. But he can have a monster of course.
SB definitely has top 10% (actually i think top 8%). Without notes it's zero call for me. Maybe call and fold seeing ace.
People who says "ez call" play higher stakes at which capping with J10s on SB is ok.

I certainly didn't feel it was an "ez call". And to be clear, it's not so much the SB's capping range I'm worried about; it's the fish who 3bets.
Note again the read I had on this guy: I'd played 50(ish) hands with him, and hadn't previously seen him raise pf. Not once, and had previously seen him cc ip with as much as AKo.

So maybe he's suddenly spazzing, but his hx wouldn't suggest this.

If I make the call, what's the plan post-flop? I'd assume I'm basically insta-folding the flop unless I flop set/quads, or something like 6-7-8, yes?

The times are few and far between in limit holdem where you should raise preflop and then fold to additional action. I've done in many 5 times in thousands of hours of play and it is usually when I open some cheese like KJ or J9 and two really tight players 3 bet and cap in position (or if it is a 5 bet game).

It is 5 cent, 10 cent and 50 hands is not a large sample size.

With regards to floating the flop, assuming SB bets at you, you'll be getting around 10 to 1, so you should be peeling a lot, but it depends a lot on the flop. I'd probably fold a AK2 board, but I'd call a 345 board or a J76 board.

Even if you *knew* he had AA-QQ/AK, I think you can call here. The bonus of him having a narrower (stronger) range is that you should expect more action than usual if you flop a set. So your implied odds are bigger than normal. You can also play better against a range that's narrow because you have a better sense of what to expect.

But 50 hands isn't really that many, so don't assume too much.

The action matters. I wouldn't insta-fold an overpair. If you're "not worried" about SB's range, you may want to call/raise a flop bet depending on the flop texture. CO behind is going to be tough to figure out because you have to act before him, but that's poker sometimes.

There are lots of such guys. They call with offsuit AK and from time to time 3bet suited broadways or A10s.
The set is a great hand but it doesn't guarantee 100% victory.

I've been away as well, but I just played my first LHE session in two years last night. I'll try to jump back in to the strategy. I was VERY rusty.

For this hand I agree you can call flop and post should be pretty easy.

Don't fold pocket pairs and suited hands that you would open with for two more.

One of the biggest mistakes that I used to make was assuming that a person who hadn't raised in an hour or two was automatically nitty tight. Some people never raise AK, Some people mix it up. In addition to having some good implied odds if you flop a set, sometimes you are up against two players who have big Aces in which case they hold each others outs.

One of the biggest mistakes is to think that having flopped a set, you won a hand.

Just because you don't flop a set doesn't mean you've lost the hand.
