I would fold on the turn.

Yea, unfortunately we are to deep to shove this flop. As played, I'm hero folding the turn as well. No a great barrel card for villain, yet he continues, which usually is a good indicator of strength. We have 8 outs with the st8 draw and 5 outs to improve our pairs. Looks like we need around 33% to call, we have 26%. 

hi A_to_theG, i try t help you:

the point with this spot in my opinion is that oppo here 99% of the time on the turn,is beating our 78o (1% is when we have found a fanta aggro donky mega spewer which have bluffs in this spot) because here is representing a range like 99+... as pbogz said,talking about pure odds,we need 33% for a correct call..obv this isn t the case..but also the main problem is that if we call the turn and the river came a 5,T, or 7 which improve our hand the board became sooo straighty that sometimes (not the majority of the time, but sometimes )our opponent can fold against our shove because even a stupid donk can think that his AA are not good on a 4698 7/T/5 board (if the river is a clubs even worst)...so in my opinion the point here is even if we call and catch our cards on the river we are not 100% sure that opponent will pay our shove so--->not safe implied odds so---> fold. 

this is my opinion and obv i accept a lot of critics and i hope u appreciated the answer!! cheerss!!
