Hi,

AKo in SB, against BTN.

5 limps, including BTN, i make it 42 euro, only BTN calls.

Pot= 100 euro, Flop 984ss, i cbet 64 euro, BTN calls

Pot= 228 euro, Turn Ac bringing backdoor clubs, i bet 130, BTN calls

Pot= 484 euro, River 9d

Question:

What would be our best line on the river b/c, b/f, ch/c, ch/f

Some info on Vilain:

Vilain is an older friendly gentleman who is one of the marks on the table, he drinks alot of beer and we can consider him pretty drunk.

I have seen him do the most crazy shit , shipping 55 on J96, jamming any A on wet boards, limping KK on the BTN, etc etc, he is an all around terrible player. 

I thought my best line should be to ch/c to give villain a chance to bluff his missed FD/SD as well as betting Ax

Vilain overbet jams the river, we?

Since of late i started to play some more NLHE after a hiatus for a few months, i'd really like you're input

Thanks in advance!
