Hey im from New Zealand, been playing holdem for about three weeks at my dorm, its great fun and we play low stakes no limit (we cant bring more than 5 bucks in coins to the table each week, but theres no limit on betting)

Theres usually only about 5 of us playing, but it comes down to just 2 or 3 players by the end of the night, which is where I lose out.
We dont use the blinds, we pay 5 cents ante before the game starts, then get dealt our cards, then theres usually a 5 cents bet before the flop. I usually fold on the flop if i havent a chance because the betting goes at about 10 or 20 cents here and 20 or 40 for the turn and river.

The best guy there whos been playing for a while has this betting strategy where he bets big in the middle rounds and forces everyone out. He rarely folds. He claims to have this big bluffing strategy that i cant figure out, although I think he just bets real big after the flop if he has a good pair or a flush/straight possibility, and keeps betting big trying to get a good hand on the river and/or force everyone to fold.

My problem is that I never bluff, I always pay to see the flop if the price is small and usually fold there if i dont have a chance. So Im always checking or calling, so if i raise he knows I have something good.

So we're all amateurs, any tips for winning a one on one game with an aggressive player when im a tight player whos scared of betting? or just some general tips you can give a newbie who knows the basics...
cheers.
