questions:

preflop, is this an automatic call given 5 to 1 odds?

on the flop, i bet out really hoping to take it down. i thought i might have the best hand, and if i didn't, i had a gut shot 9, another 10 and (maybe) a jack would make me the winner, since it would be hard to put the flop raiser on a 9 if the jack did fall. i knew if i got raised big i was going to fold, but the raise was only the minimum and a call seemed automatic to me with my hand at that point.

what do you think? room for improvement?
