I think this river is way better for our range than his range. We just have way more Ax on our range. I will check all my AK on the flop and call them on this turn. Also we have A4s A8s/A2s. He onnly has 2 combo's of A8s (which may not even bet the turn) . Also I cant see many Ax bluffs on the turn. So I think we have to create a leadingrange on this river.
We could turn all our 8x in a bluff and balance this with our Ax.

bluffs:

8Ts 2
78s 2
97s 2
9Ts 2

8 bluffs

value:
AK 12
A8s 2
A9s 2

16 value hands

if we lead pot on the river we he gets 33% odds. so we can add 1 bluf for every 2 valuehands.

I think it is nice to ch/r our 99(this hand I will also check flop with) We block his medium valuerange(which always will check back this river. And its nice for protecting our checkrange.
