I raised it up to 1600
He then pushed all in
1400 left call/fold?
Never ever raise half your chips then fold, once you put 1/2 in pre you are in for good
never put 1/3 of your chips in then fold
once you raised you should call
but i would of prefered to have pushed them all in the first place rather than raise 1/2 your stack putting him to the question
