Pot size: 10
Hero bets 10 (pot size 20)
Villain min-raises to 20 (pot size 40)
Hero must call 10 into a 40 pot. 4:1 on the money, not 2:1. You now must win this hand 1 in 5 times. (This is a good lesson to you habitual min-raisers out there, you know who you are.)
Great points. I do want to hear more.

BTW, I love making blocking bets into min-raisers because they will just hit raise against any non-trival bet, allowing you to price your own draw with some fold equity to boot.
