I dont C-game that often, but sometimes I give it a go..
I like betting small sometimes to block calls or get value from worse hands or even semi - / bluffs as in this particular case.
Would like to hear your thoughts about this hand/hand range he could have played.
I am thinking like A5 Diamonds, which could PF open and call my 3bet.
Flop call with a pair of 5 and turn Raise defend his flush draw and fold on river shove.

But I am not as genius as people here on this site, I play poker for a long time but I feel like a newcomer here :D

Hi there!

My name is Peter, on PokerStars known as Closed Bo0k.
I started playing poker at the age of 16 for free chips. As soon as I turned 18 I started to play for real money to get to know the game better.
After playing 2 years of low-stake I made a $3900 cash in a $5 re-buyer game for 2nd place finish of 2196 entrants, This changed my look at poker.. even though I still kept playing very low stakes, Could this be something for me?
Trough out the years I always played poker as a hobby and tried to get better using every learning aspect .. Poker on TV, Watch streams on twitch, Reading books, Replay my own played games, watch YouTube, read articles & forums and even stream myself.
I have a full-time job working for Corsair (gaming company) but I take poker slightly more serious now,
I feel like I am getting better and performing more steady in large field MTT's. About one week ago I made my biggest cash so far .. I won the $11 Bounty Builder with 5729 entrants for a first place of $2330 + 2350 on total bounty cashes. ($4680)
I still have the dream to live my life as a professional poker player and I do realize this wont come easy.. Its very hard work and it's not for everyone.
So besides my full-time job I am now a member of RunItOnce to educate myself more in poker,
I use PokerTracker 4 (full stakes NL Hold'm) and ICMizer 2 (for upcoming study)
I will start this adventure and I am very excited! I will study a couple of hours a week to improve myself, I will watch video's on daily base and make notes to improve my overall poker game.
All advice is more than welcome,

I am Peter .. I have a dream
