Hand a friend of mine played on a £1 £1 game in london.

History: villan is a young 20ish kid who is v capable of reading hands and acting accordingly. Has just sat down and has announced he is loosing 200.

Hero is viewed as good TAG and is winning ~30, sitting on £130.

Limps around to hero in mid position with 44s. Hero limps and 3 limpers join behind.
flop = 346, 2 diamonds
sb opens for 10 folds to hero who makes it 28 total.
1 caller behind and everyone else including sb folds.
turn is Jd.
hero checks and villain shovs for heros remaining ~£100.

Thinking here is when hero checks turn after limping pre and raising sb a flush is somewhat never in heros range. Villain is def capable of reading heros effectively face up hand.
Dont flushes bet less for value and sr8s or bigger sets re raise the flop because of all the players behind and small blind???
just seems nut flush draws are the only flush draws that are calling the flop with this villain and are not shoving when checkd to on turn.

Really? People call here with any flush draw to a small raise like that. You are wildly over-estimating the discipline of live poker players. They will probably always call to a larger raise, so the flop raise should be to 40 GBP min.

Everything is consistent with a small/medium flush, and they would make up around 70% of his range here IMO. Add in the bigger sets and straights and we are not getting the right price. After the strength hero has shown on the flop, it's a horrible spot to bluff because people very rarely raise flop / fold turn. If villain can read hero's hand for a set, then he is going to jam for value. If he regularly tries to bluff people of sets it would explain why he's down 200.

Fold.

too often a flush (minority of times a straight) to call.
simples.

I actually think that in low stakes live games (like 1/2 and I guess 1/1) limping small pairs is fine. Games are passive, players are weak, and you can easily bloat a pot up if you hit post flop. Set-mining on the cheap is great because you really can take lots of people for tons of money when you hit and the opponent is a bad player.

However, I generally play 200BB+ effective at 5/10 stakes where I open raise all pairs even over some limpers.

I think limping or raising here are both fine. If you play against thinking opponents to whom your flopped sets will be face up if you limp, it's important to raise more often with small pairs. However, in LLSNL with all of the passive games and hand readers often scarce, it's usually fine to limp behind (not open limping, I would still raise).

If your table is loose pre/fit or fold post though you can raise and take down a lot of pots post that you wouldn't be taking down w/o a raise pre.
