this means you will not be able to come in for a limp preflop much at all (say with q-7). paid off nicely.finally, if you raise the bb alot, they will play back. they may keep betting with weaker hands thinking you'll fold and you can get some hands like middle pair, top pair, etc. if u check to them on flop, turn, river, etc. also, if they see u not raising them much, in a tourny, when the blinds are bigger and a steal would actually increase your stack by 15% or more, they may be more inclined to lay down to you when u do decide to raise.also, another reason i like limping is cause a lot of people are aggressive in fixed limit when they have position. if they see you consistently limping and not trying to steal their bb in these situations, they will not get upset with you and play an honest postflop on these blind battles.
bb has position on you.hopefully u are sitting next to the same person for a while. there is a theory that goes something like this, 'the more money in the pot, the more tempting the pot is to others' this is mostly an idea for pot limit games, but also fits well in blind vs blind making the pot bigger, there may be a higher chance the bb will bluff u out of your winning hand successfully, whether u got middle pair or just ace high.
