This is just not the right way
to go about doing this. I
don't like to rip on people trying to help, but this is like the most confusing way possible to approach the topic because there are so many 'what ifs' to account for.
The easiest way imho is start with a baseline read (aka, what would I have if I was him?) and adjust for player tendency from there.
Ex1:
Unknown person opens 4x
UTG. The only logical way to approach giving him a
range is to assign him the same
range you have when YOU
open UTG.
Ex2:
Unknown LIMPS
utg. Slightly different because you never
limp UTG. So
draw upon your experience of what other people who DO
limp UTG usually do it with.
As for KNOWNS, you simply adjust what YOU would do to what THEY would do. If you run say 12/10 at FR and
open {
range}
UTG, then you can make perfectly good assumptions about what a 15/12 opens
UTG with (Hint: its basically identical due to
position).
Just note the following
1) you can't really go wrong assigning a slightly too
tight of a
range to an
unknown.
2) peoples ranges get wider as they get closer to the
button. A 20/15s
open UTG range is probably not too different from a 14/10s
open UTG range. Their
late position range, as
well as their limping and cold
calling range is probably wider.
That all comes into play LONG before you consider whether he likes SOOOOTED cards too much or anything even remotely that specific. Get a good baseline, and adjust from there. And the best person to get that baseline from is yourself.
This is called
level two thinking.
