raise more pre-flop??? or just check and take the flop? i wanted to win it right there,,, so i guess i shouldve rasied more. but i got it heads up which i also wanted. i made a standard continuation bet on the flop and when he called i decided it was time to give up.

what do you think is better? rasie preflop or just check and see what happenes?
