Ok so i got bored with playing cash (as i often do) and decided to deposit $220 (100BI) for the $2 180 mans (turbos). Going to attempt to grind up to 100BI for the next stake.
I use to grind $16 SNGs back in the day and was pretty much breakeven. Check out my sharkscope graph

. So my i got some background in ICM.
Ok now the questions:
1) So i take it early on in these 180mans there is very little ICM consideration ? Take small edges ?
Yep, take any edge you can find
2) Start considering ICM near the money as the difference between 0 return and double your money warrants consideration.
Your better off ignoring the money bubble and just abusing the fact that most tables tighten up considerably. Generally a great time to build a stack
3) Once in the money gamble it up till near the FT bubble as pay day jumps again?
Yeah still take small edges as your stack will usually be in the 10-30BB range and have little room to work with
4)When i was playing SNGs i use to push bot <15bb, and make small raises with 15-20bb. 20bb+ mostly 3x it. In general is this still a good approach?
When antes come in, 2.5x. Shoving with <15BB's is a good idea
5)When it comes to reasteal shove what is the ideal stack size ? We dont wana give our opponent 2 to 1 so that is a 10bb minmum but what is the maximum?
Most people resteal with 15-22BB effective stacks
6) Am i ever jamming 15bb+ unopened ?
Good spot to do this is blind-vs blind vs a guy who is capable of restealing
7) Is a 100BI roll reasonable ?
Seems fine, maybe a little more for big fields (1k+)
8) When to use the stop-go ?
Pretty much never see it anymore because it rarely works
9) How important is a HUD, and if using one what stats/setup ?
Definitely helpful but you rarely play long enough at a table to get reliable numbers. I'd avoid putting most postflop stats in your HUD. VPIP/PFR/Attempt to steal is what I use
