I like the 3! and prob call in game but fold is prob correct,..against a tighter player (8-9%RFI at 6xBB), this is a snap fold and close between call and 3! the first time around, but since the guy is laggy and might open 16-17% RFI from EP, I like the 3! for value. Obv getting cold 4 is bad, and again folding is fine, but calling some times here is def +EV. Using a range of AA,KK, a third of the combos of AKo and half the combos of AKs (it also had less than a combo (7%) of QQ) Hold em resources calculator still calls a third of the time with TT (it also lists the call as +EV). IMHO having a low SPR on the flop helps us with TT as we realize more of the equity of our hand as we can go with our hand on non-A/K high flops (we also have AxKx in our range pre- so we can have a few lead bluffs on low boards... Its not like this is a huge +EV move vs V's above range we only have 30% equity on most flops so pretty much we're going to have a tiny +EV play on the whole...
It's prob not necessary to increase your variance like this at 1/2 but it's something to think about if you are going to play higher eventually and don't want to turn down neutral ev spots to enhance your overall strategy.
Also interesting to me is how HRC has the original raisers strat, I put your 3-bet range as 99+, AxKx and AxQy and I set EP raisers range at 17%, and the 4-bet range as the above (AA,KK)@100,(QQ)@7,(AxKx)@50,(AxKy)@33.
It has EP only calling 10% of its KK and that's it
It's jam range is AA and 10% Ax5x...
