re: Poker & when to check raise?
If a guy is aggressive, betting every time I check a flop, I'll check raise him light (as a bluff) on occasion.
I'll also check/raise that guy when I have a hand to get some more chips and give him improper odds
to chase a draw.
Another check/raise opportunity is when M is low, I have a big hand, and they'll feel committed to call the check/shove (often because they have the proper odds to do so).
For example, lets say that I have 4k and the pot is 3k and I check, they put in 2k with their overcards, and I shove for 2k more. Now it's 2k for them to win the 9k that's out there (instead of me just shoving and them having to call $4k to win a 7k pot).
