yes but whats a monster here. if he pushes a boat then he is idiot.
i think he is pushing a strong draw while he has odds so he dont have to make decision on turn if he miss (he may not get correct odds at all on turn in fact).
but by ur minraise he may actually put u on a draw and protect his 8. so a monster here would be 8 with better kicker.
we should include 6h8h into his range if we put T8 there aswell.
