online 20/40 capped 4 ways preflop,flop,turn.Call river with TPTK?

[NLfool]

Sobedude's big pot hand reminded me of a wild online game last week (6 handed).

I have AhKh in the CO and it gets capped 4 ways preflop

Flop is Jx 9h 2h it is capped again

Turn is Qx again it's capped

River is an A and it goes bet, call, fold there is about ~1600 can I really make this call? But I really think I can buy a lot of fast food for $40.

The caveat is that this is online.
