What is the minimum preflop range I have to play to have on every 5 Card board the nuts in my range?
E.g. On a: As 4s 5s Kc Qs Board I would need 2s3s But I guess there is no board where you need any 27o to represent the nuts.
To have every nut hand in your range:
22+, 32s+, 42s+, 52s+, ATs (pocket pairs; suited 0, 1, and 2 gappers; ATs)
Since straight flushes are covered, straights are as well.
Any time a straight flush, quads, a flush, or a straight is not possible, the nuts is a set, and your pocket pairs have that.
This range covers 16.1% of starting hands.
I'm pretty sure that based on your nuts definition you have preflop range of 100% because on preflop you can't imagine what is nuts and what not and on preflop you dont see any common cards then you must call every hand to look on board and do some calculations.
This is based on that you must have nuts in range then 72o is nuts possibility too. For example in board
