raising pre seems fine to me. i typically no bigger than 3x pre in any position at a 6max table unless i'm looking to isolate/build a pot vs some drooler who wont fold vs bigger sizes. as played i'd typically bet $1 on the flop here, same as i would with AK or whatever, but i definitely have some betsizing issues so that could be incorrect.

edit: wee bit drunk. didn't realise it was Axx and not Axy flop. yeah i'd go smaller than $1 here as standard. probably $0.7-8
