$3/$6 to $5/$10 2.0% / $0.50 3.0% / $2.00 3.0% / $3.00
$10/$20 2.0% / $0.50 2.5% / $2.00 2.5% / $3.00

Still, it's very worth noting that the conventional idea that the Nash equilibrium is optimal is based on the game being zero-sum.

Poker games are often not zero-sum, and so the Nash equilibrium can be non-optimal. The most obvious example is rake, but another example would be tournament play when in or near the money. Say that there are four players left with stack sizes of 500, 90, 90, and 20. If the two guys with stack sizes of 90 end up heads up in a hand, it is most certainly not zero-sum; if they clash hard over the hand when it's close to a toss-up (such as NLHE underpair vs. AK), it's very -EV for both of them. The more they risk on this hand, the more tourney equity that accrues to the small stack -- no matter who wins.

This is odd... Villain would be betting 1BB to win 6.5BB, so he is getting 13.3% odds on his bluff. So shouldn't the NE for the T987 be to fold something like 13.2% of the time to make sure that he can't profit by bluffing at all?

I thought if one person deviates from their NE then they will lose if their opponent is playing NE. You're saying GTO can't do better than breakeven against a non GTO opponent? That doesn't seem right.

It is not guaranteed that if you play NE and your opponent deviates, then you will automatically profit. Think for example of rock paper scissors. The optimal strategy is to randomly choose R P or S. But against your NE strategy you will break even against EVERY other strategy, regardless of how he plays.

Okay that makes sense. So really we would only want to revert to NE if we felt like our opponent was better than us in a certain spot, and that we would always be one step behind. I'm more interested in the NE folding frequency with our bluff catcher though. There's only been a few people where I thought, "I wonder what the NE bluff frequency would be" considering everyone calls 100% of the time with their bluff catcher, but almost everday I run into opponents who I really should have a set percentage to be hero folding against.
