1) Yeh people limp for £1, prolly not going to fold for £7 speshly when others have called as well, as far as what I'd be isolating i'd be going for suited Aces broadway hands, bigger aces etc, stuff that people will have limped and called with dominated stuff, so the pre-flop value is that on KT4 they have K8 you have KJ, on if it comes 459hh they have J6hh you have A2hh and so on, and you can pretty much imp behind with anything you want, i'd fold like 92o and stuff but could prolly make a case for that not being terrible lol
3) No, because its still 9 handed NL and there is a high chance someone behind you will be waking up with a monster, same as before you'll be the guy getting "priced in" with dominated junky hands OOP.
4) impossible to answer without being there and knowing the player, some people prolly iso plenty some people prolly dont even iso QQ
Hope this helps

Cheers lil D- big fan of the blog!
To add more info to point 4, he makes the ISO to 7, he then gets at least between 2 and 4 callers before us. Do we then just make a pot odds decision on our hand, or just go with pretty much anything?
In addition to what Suprslim said you can make your size as big as they will cope with. I've played in live games where you could 10x preflop before any limpers and still get callers. Just keep going bigger until you find the sweet spot. Some nights it might be £8 some it might be £15 but don't have a hard and fast set rule, learn to adjust.
Contary to Suuprlim I wouldn't be opening hands like A2s-A8s as they don't flop enough pairs, just let it go off multiway. I'd also be limping behind hands that seem pretty weak like k2s and q6s. Limping behind in late position things that don't flop lots of top pairs will make your life easier. Play as tight as you want, it depends on your comfort level and the table. Don't be the guy who starts playing with solid fundamentals who then descends into limping 43o utg etc. I'd also say limping 22-77 might be wise from quite a few position especially if we know it is most likely going to go off multiway.
Thanks for the advice!
I in the 3rd hour I was there I did exactly what you said, I was limping a tonne trying to get into the game. I felt like a tool after a few orbits, and nitted up

If we think we are always getting callers with a £7 iso, should we be isoing bigger. I usually 3x + num limpers. I think next time it will be more of a 4x plus limpers or bigger if we have a premium hand
