probably retarded question HU

[luegofuego]

game is $8/$16 HU. ive been super hyper aggro, he stacked me like 3 times to start things off, once with a retarded suckout when he shoved a gutshot on turn vs my top two, twice with super light (read retarded imo) calldowns that were right both of the times. ive been battling back and hes back down to about a $1,800 stack again. ive been 3betting him a bunch, checkraising a bunch, 2 and 3barreling a bunch, etc. he thinks im a spewtard i guess judging by the retarded calldowns. ive seen him C/R bluff a decent amount on like JJ7 and KT2 boards and checkcall JK and stuff on the same boards so i dont know how much he cares about balancing... hand in question: he opens button for $48 as usual, i 3bet Td6d, he calls as usual. flop is 654, two spades. i bet $240, he shoves. $1,500 or whatever for me to call. be heroic? i thihnk this a draw like a huuuge part of the time obv, but i have to be right a huge amount of the time...
