Hm I found out being called all the time playing these microgames thats why I dont think that there are a lot of tactics possible. I would have Pushed it all the way holdin KK hopin not to get beaten by AA

But with this mayor Flush draw I would have checked waitin for some on else to make a bet on ther flush (or bluf) in order to reraise them. With these mircogames someone already in for a big bet on the river shall (99%) always call your reraise
