re: Poker & Reasons to Raise
in tournaments i raise sometimes in late positio; if a number of people limp in before me and i have a decent hand. (maybe mid-pockects or mid/high suited connectors) i might raise a bit on the button or the BB to see where everyone is at. ill watch to see which limpers fold and who simply calls. that gives me an idea of what type of hand they might have. a hand worth a limp and a raise, but no reraise tells
me they might playing small pockets or maybe a high card and mid kicker (K/9). if someone reraises over me, its an easy fold for me. the way i see it is i might have lost a few chips, but i have a whole round of hands to play with before i really have to put anything (blinds) so i have a chance to get back the few i lost.
if i have a pretty decent read on the players, i like to raise late not only to kick out players looking to get in cheap with small hands, but also to see what other players do. i might raise with a not so great hand to see where other players are and then try to out play the player, rather than their cards.
