OK, that seems a bit more sensible. Personally, I'd prefer to play more Kxs and fewer OS1G, but I don't think that's too major a deal. Those straights you're mining will be more concealed and nutted than K-high flushes, anyway. I think you can safely add { 64s,53s } if you're comfortable with { 75s,54s } in your range.

OTF, you have 382 combos
A) 35 combos -> 9.2% (was ~2.5%)
B) 12 combos -> 3.1% (was ~0.5%)
C) 79 combos -> 20.7% (was ~15%)
D) 256 combos -> 67.0%

This range is much stronger... not just on this board but on most boards.

The question now is what to do with those ranges. As always, we need to know Villains' tendencies to move forward with that.

MP, the pre-flop aggressor, has a 91% C-bet stat. So it's hugely likely that he will barrel quite loose.
CO folds to most C-bets, so I expect a fold, maybe a call. A raise probably means overpair+.
SB has already checked, so probably doesn't like his hand too much, and the note says passive, so I expect a c/f or a c/c. IF SB calls, I have to put him on a strong range, and the strength of 77 against his continuing range is probably very weak.

It strikes me that if you check, MP bets almost all the time. So you get to see what CO and SB do without risking your own chips.

Given these data, what portions of your range fall into the b/f and c/r categories?
