if nobody raises pf, in general since getting half-price entry, what's the loosest/typical range you'd start with, to flat in sb pf?

example I would'nt limp in w/ J8o out of position with 2-3 limpers but if I was in sb and no more than 2-3 limp in pf, worth flatting from sb?

If my villains are typical low-limit terribad players that can't fold then I'm okay completing the small blind with any hand that can flop/turn the nuts.

Connectors, one gappers, all broadways. I won't complete 3-gappers like J7 or Q8 and I'm borderline if I will complete 2-gappers like J8, I'll more likely play 2-gappers if there is significant limping with 4 or more players.

The problem though is having the discipline to fold post flop when you catch a "piece" of the board. Too often, a player will complete the SB with something like J8o hoping to flop gin, so he completes, 6 way action and the flop hits

Flop(6bb): J 9 4
SB chks, chks to MP who bets 3bb, CO calls, BTN calls, SB???

This is the exact situation where SB gets in trouble and leaks an additional 3bb - 15bb by check calling the flop and turn and being forced to fold river. Note in the above situation that 1/2 the deck is scare cards. We don't want to see an A, Q, K, T, 9, or club: and even an 8 can lead to us getting stacked. Also note that we can easily be dominated by bigger Jx hands in V's range.

the above situation is the real reason why we need to fold the SB, because too often we catch just enough of the board to pay off our villains.

For everytime we flop a full house, there will be 50 times we don't. And we won't make enough money when we flop that full house to make up for the 50 times we whiffed and/or got sucked into paying off one or two streets as we check/called down with some weaksauce TPNK or gutshot draw hoping to bink...

Avoid offsuit junk, except perhaps KQ. Complete with all pairs, suited aces, suited Broadways and suited connectors down to 54s.

Don't go broke with less than top two. Mostly you want to make trips, a straight or a flush. One pair multiway in a limped pot is usually a check-fold.

thanks, smart answers... great hand outline dgiharris; I appreciate it. I realize how ignorant I am of the game when I read smart answers like that; you guys really know the details.

altho i'm a top-iq guy who's read most of the good books, watched hundreds of hours of wsop footage, practiced a couple hundred hrs in vegas mgm etc casinos and 100s hrs on playmoney sites (got my 2k ps to >2m grinding), i've been studying this for years and am still kindergarten-level knowledge compared to you guys; hope i catch up. i'm impressed with how detailed/hand-specific your folks' thought processes are on this.

thx too for the insight on post-flop fold discipline needed from weak SB hand, then needing to fold to scare cards later, That's a smart observation; thank you, sincerely; it's a perfect example of the kind of mistake/leak I make regularly. good example of "makes sense, you're right, how in the world will a fish like me learn all that insight?" for situational playing patterns... thx for the tip. there's so much to learn, i still wonder how the 20-something pros learn all this in short time they've had.
