re: Poker & The small blind completes
I've been forcing myself to always raise. The very rare situations where I don't raise and complete the blind is simply when there's a lot of limpers and I want to see the flop with a very speculative hand, like a small suited connector. As I see it, I'm paying half the price of seeing the flop.
On the other hand, I don't complete the SB with a big hand (AA KK QQ AK) and raise because I think that these hands behave much better against less oponents. I do the same for the BB also, if there are a lot of limpers and I have a strong one, I'll raise.
