playing 0.25p/0.50p £70 deep
9 handed. utg,mp,co and btn limp, I'm in sb with QQ
I raise to £3,bb folds utg and btn calls
flop comes A65
I c-bet for £5 then utg ,about £60 effective, then raises to £15 btn folds

I dont really know what to do here as i think utg probably has an ace (or low flopped flush) he's trying to protect since most people in this game will always just call with the bare nut spade draw so I don't think I should 3-bet. I also dont know about calling since it gets weird on brick turns since I dont think I can call a barrel and if i do hit a spade I dont think ive got any implied odds unless hes specifically got AxJ or a flopped J high flush and I've got reverse implied odds if they've got K . so here do i just fold flop or is there a better play.

Preflop should be bigger. There is £5.5 in the pot already when it gets you, make it £5 at least and possibly more.

Without some history and read on this specific villain this is a fold. You are already representing a big ace on the flop and got raised anyways. Plus villain raised to 1/4 of his stack on the flop.

Preflop should be ~£4.5 I think.

Flop should be a check. No reason to bet this hand when you have a spade. Plan would be to check call twice and fold river UI I think.

As played I think this is a call and fold turn UI. You're getting direct odds to draw to a spade and you're saying people don't tend to raise the bare nut flush draw.
