Hi all,

I'm trying to move up in the world of ranges and start to construct a defense range vs OR when I'm IP. This strategy wants to be something like a "general strategy" based on my field tendencies. Firts of all, do you agree with these general rules?

- Defense IP something like half of OR range;
- Defense a little more or a little less of this half, based on your relative position;
- Calling IP is a bit better than 3betting;
- 2:1 is a good call:3bet ratio.

Well, let's start with my population analysis. Today I try to study how I should play vs. UTG when I am in position. These are reg's UTG preflop stats:

RFI 15.6% (55+, ATs+, KTs+, QTs+, J9s+, T8s+, 97s+, 87s, 76s, 65s, ATo+, KJo+)
Fvs3b 50%
Fold flop vs CB in 3b 40%
4b range 2.5%

In this scenario I've changed 2:1 call:3bet ratio in 1:1, because of their low Fvs3b and not excellent (for our bluff cbet range) fold vs cbet in 3b pot, although a standard half pot cbet makes a little profit against this tendecies too. I also choose a depolarized 3betting range for the same reasons. Something wrong at this point?

Let's try with MPvsUTG. I've to defend a bit less of 15.6/2 = 7.8. I choose my 5bet range; probably pretty easy against a 2.5% 4bettor who (almost) never folds; now it's turn of 3b and CC range. I'll 3bet all hands with >50%eq vs. UTG Call to 3b range:

4b UTG range (QQ+, AK)
Call to 3b UTG range (88+,AQs+,KQs,JTs,T9s,98s,AQo+,KQo)
My 5bet range (KK+)
My 3bet range (TT+,AK)

And call with some good playbility/high IO hands:
(99-88, AQ, JTs, T9s, 98s, 87s)

Total defense range = 6.79%

COvsUTG
Now I'll try to defend exactly 7.8%. I have to add something like 10 combos (5 in 3b and 5 in CC ranges). Because of my depolarized range I have to add the top of my CC range in the bottom of my 3betting range; in other words, 6 of 12 AQo combos. AJs and 77 seems the best candidates to add 10 combos in CC range.

My 5bet range (KK+)
My 3bet range (TT+,AK, AQo 6 combos)
My CC range (77-99, AQo 6 combos, AQs, AJs, JTs, T9s, 98s, 87s)

Total defense range = 7.54%

I'm I on the right way? In next days I commit myself to analyze BTNvsUTG and any other positionVSposition, but first I'd like to know if I'm making any mistake. Thank you all.
