Someone did just this (folded when he/she could have checked) and I was holding a Royal Flush.
I admit, I once folded when I could have checked. Pretty dumb move really. Another time I was going to do this, but thought what if they have a really nice hand, I would like to see their cards if for free, why not. I ended up winning that hand lmao.
So now when a time like that occurs, I think let me not fold and just go ahead and check. They may be holding a Royal Flush and well I would like to see. It is not costing me anything.
Other than that, I have folded to speed the game up. Maybe I was short stacked, turbo tournament, or I did not want to show my ugly cards.
TY Cat for the picture.
