JTs flops fd and 2 overs facing large c/r.

yea i think 86s/22+ are stacking off when we catch our flush, and those combinations plus worse flushes outweight the KTcc/Axc hands in his range. i agree we probably never get to see the turn + river once he raises this flop. however i think he also raises the flop with 99/8x, which means if we turn a Jack or Ten we can call the turn again, and decide on the river.

I disagree pretty hugely with your last point about him raising 99, 8x here. Non retarded regs just don't do this very often, Especially on drawy boards where they could never justify raise/folding for value.
