When I first started playing holdem I would fold these small pairs to most raises pre-flop, then I changed (After reading AOK's strategy guide on this site) to "mostly" calling up to 4bb pre-flop in the hopes of hitting a set on the flop & winning a big pot or folding if I didn't hit on the flop.
I have since been reading a strategy book by Phil Hellmuth which advocates raising & re-raising with these small pairs pre-flop & then C bet on the flop whether you hit a set or not. (The idea being you can win a lot more pots this way than the 1 in 8 when you go set hunting & you will get paid of even bigger when you do.)
I was just wondering if anyone on FTR uses a similar strategy & whether it is more profitable, or also even if you don't use it, do you have any input as to why it would be a bad idea & finally also would it be suited to looser or tighter tables thanks.
