Weak line agst LFISGD ?!?

[PHiLLeDINGUE]

I did put LFISGD on the tilte, but it could be any player who often enough over bet the river with air.

50-100 (10k eff) 5 handed --> You got a hand like Axs and He min raised from the Dealer, you call. ($450)Flop Ax8h9h you check he pots and you called. ($1300)Turn is an 8 !!! Sometimes you bet, but for the purpose of this hand, lets say you check again and he pots one more time and you call. (about 4k)and river is a black J !! You check once more and he almost insta push for the remainning 8k in tha 4k pot !!

So here's my questions, your line looks realy weak and it's king of easy to tell whant you got, so because of that, do player like LFISGD push like this with mosthly only air ?? I mean if I look that weak, how can that be a value push ?? Wouldn't he re-pot river for value like the flop and turn play ?? And if he's pushing alot with air, would you then call with any pairs ?? or a nine ?? J ??

Or is that the he either call or fold so push line ??

And while we are here, what's up with is min raise from the dealer ?? SHould I repop it with marginals holding like Axs ??
