Am I overplaying my hand?

Wilhelm

I think that XXX is a bit of a station.  I saw him call off an overbet on the river on a 289TJ board with 82, but maybe he had history with the other guy.  I'm not too worried about xxx's stack and my notes tell me he probably is behind from his bet sizing.

Use names that look different ! lol

I just flat the minraise on flop as not sure I get called by worse by 3-betting, even at NL4, 3-way. 

Again flat turn. 

Also this board is super dry with hardly any draws apart from gutshots so to get value they need to have A5 through to AT (not A8 either). AK/AQ can play slowly so you could be value betting yourself here plus obvious 2pairs/sets which could be in their range.
