When do you find a fold here?
 

On 3rd I'm thinking I can get this heads up against 3 to a low when I'll be a favourite despite a dead queen, is this flawed? Is 4th too aggressive too?

Re: When do you find a fold here?
 

I think you played it about right. Really, the only questionable play is the raise on third. Especially with the low ante structure and a dead Queen, folding can't be far wrong. Raising to get it heads-up is fine, but you'd better be pretty sure that you'll get it heads-up. You don't want to be playing a big multi-way pot with a dead hand.

I think the three-bet on fourth was fine, and once he caps it, he's either (slightly) over-playing a big pair or he's rolled. It does get increasingly ugly from there, but I don't think there is any point at which you should really think about folding unless there's something about your opponent that you haven't told us.

I do hope you checked the river with the intention of calling.

Yes, was going to make a crying call on the river, always do with pot that size and am sure its been heavily EV+ by doing it.

I guess my real question is about a fold on 5th given he may have either made a flush, have a set, or 4 to a wheel. Is the pot always big enough at that point to call even with a dead queen? Opponent was an averge player, bit loose if anything from the 30 minutes we'd been playing.
