re: Poker & How do we feel about comitting to a hand?
I agree, doesn't seem like poker, but just like gamble.
I do choose to commit sometimes, but I do it using some logic. For example, say I'm playing against a maniac or someone who bluffs a lot, and I flop a gutshot + flushdraw. Or a draw + top pair. I may choose to commit and say "Whatever happens, I'm going to go all-in with this specific hand, on this specific board, versus this specific opponent". Most of the times I choose this because a simple bet will take a big part of my stack away, so I might as well bet it all. Sometimes there are other reasons.
But even this isn't secure, and I may back down. Say, if my top pair is a King, and I feel he has an Ace, I can change my mind and fold on an Ace turn.
