However, being too happy with big wins, so I was curious to go all in for IDR 2mln and unfortunately I lost, only getting 300K at the end, LOL.
I told you mate don't go all in at the end of your session (you are already tired, etc.), simply withdraw or keep the balance for the next playing session when you are fresh. I think I've said it some days ago. Going all in because you are already bored/tired will mostly yield negative outcome.
If you tired/bored already, just keep the balance (or withdraw) and use it another day.
