Okay, bear with me while I think out loud...
I tend to be a limper with nearly any two suited cards (not usually 72 or 83, but you get the idea). And I know there are more out there like me. I understand the idea that if they are low cards, a flush isn't a sure winner...easily bitten by a bigger flush.
However... how many time have you mucked two crappy cards (regardless of suited or not) only to see that had you played them to the flop, you'd have a monster? It's happened to me about a dozen times over the past week (both live and online) with 47. I would NEVER play 47...even folded it suited live on Saturday because the blinds were getting too high to play crappy cards like that.
Okay, now...an arguement could be made that you should limp in with ANY two cards at any time "just in case"... After we've played a while, we come to the realization that you go broke in a real hurry seeing every flop, and start to be way more selective in what we play. But every so often...there's that hand that comes up, "If only I'd played those crappy cards..."
So...I look down and see two crappy cards...but they're suited! Lying to myself about the flush possibilities, I limp in...and every once in a while they hit!
My point is...we can't afford to see EVERY flop...but if we just play the suited ones to see the flop...we get a chance to catch something every once in a while that we wouldn't have ordinarily played.
Do my ramblings make sense?
