Checking With a Chip

Last week I wrote about using either/or thinking to mislead your opponents. Human brains like to make decisions between two options (either I’ll do this or I’ll do that), and therefore people sometimes make logical errors when analyzing decisions with three or more realistic options.
There’s another either/or error that arises commonly in no-limit. Here’s an example from the message board.

Hero?
Pawel asks:
Why do you bet that little on the flop?

I am not quite sure why I bet so little. I normally would bet 1 or 1.5. I actually didn’t notice that when I was reviewing the hand.
We’re used to thinking that you have two options: check or bet. Either/or. But we don’t have two options, we have many, as bets can be various sizes. Betting $0.50 is very different from betting $1.50. Yet our either/or brains tend to think, “Is that a check or a bet?” and sometimes tend to group all bets together regardless of size. The example I provided isn’t the perfect one, but it demonstrates the point nonetheless — people tend to lump all bets together in their brains, sometimes missing the distinction between a $10 bet and a $100 bet.

I noticed that sometimes (in tournaments mostly) people try to rob others off their cheaps making tiny bets with good hands all the way and then bet large on river.
