I have been playing very solid as usual, showing only good hands at this table. I spotted a place to make a move on this hand. MP2 calls first, and MP3 raises to 3$ which he has done alot and with very weak hands. Button calls 3$ and he is playing very loose, calling alot of pots with weak hands. I saw my opportunity to mix it up, made a raise to 12.5$.. 9.5$ more to call for the button and mp3, maybe I should have raised more ? Well the MP3 folded as planned but the button called, which wasn't too big of a suprise for me.

Flop comes and is pretty interesting, I know many times I just take it right here with that flop. So I bet strong 25$, Button insta calls. Insta calls was clear to me, he has a weak ace or a big club. Thats my read here. So theres +70$ in the pot.. I have 60 left, button covers.. I need to get a fold almost 50% of the time if I push. I think its close because he is a loose and maybe alittle calling machine. Well Still I decided to bluff...

Overall what do u think of this play?
