Interesting Spot Not sure what to do

[niner1984]

Last night i was playing in a small home game and this hand came up and i am not sure what is the play..

We were down to to 6 people and the blinds were 150-300 every one folds until the button limps in. the small blind completes and i look down at so i decide to check.

stacks button 11k small blind 6k myself 5k

the flop comes

small blind checks i feel my hand is big so i decide to bet 600 button raises me to 1600 total my read is he does not have much which is his read on me. The small blind tanks and moves in for 5700 hundred . I have 4100 hundred back what is your play here call or fold?
