One thing to consider when calculating equity and ranges is that villain's bluff% is always > 0. For close EV situations, you have to consider some air in his range.

So, in the ATT3 hand, OP had the range as {AA, 33, AK+, Tx}, but I think you have to include *some* hands like JJ, QQ, KK or QJs as part of the range, because if you don't, you'll wind up folding close calls that may be more +EV than you think.

*Disclaimer* I have no idea how much bluff to assign to villains. Obv, you can read betting patterns to sniff these out, but even if you're just looking at the cold math, you could throw in 72o to allow for some bluffing %.

What do you guys with some actual skill think of this?
