re: Poker & small pairs
In a cash game, I'll limp with them from any position or if the pot has been opened to a sensible raise, I'll call. I don't want to spend too much money preflop with them. I'm just looking to hit a set on the cheap. And by only limping, I hope to have multiple players seeing the flop thus more chances to get paid nicely if my flop does hit. If it doesn't hit, I just let it go. I follow a strict "No set, No bet" policy with small pairs.
In tourneys, same philosophy while I'm in the green M zone.
When my M is between 10 and 20, I'll open raise instead of limp but I wouldn't call a raise with them because it starts getting expensive to look for sets.
When my M is less than 10 but greater than 5, I generally throw them away. I'm either dominated or in a race for all my chips and I could wait for a better spot to double up.
When my M is 5 or less, i shove and hope for the best.
