check raise all-in on the flop? i dont like the play

Stack depth is a real key here. With 100BB, especially if the pot is raised preflop, it isn't really going to matter. Check-raising is often going to be a good way to get your entire stack in against an aggressive LP player who, after betting, very well may have odds to call your raise.

If the effective stack is quite large, then check-raising becomes a bit more problematic, for a couple of reasons. One, it defines your hand quite well and allows your positionally advantaged opponent to play almost perfectly against you. This could include them letting go of the underset or picking up enough bluffing "outs" to make a call reasonable.

Obviously no line is optimal in 100% of situations and I can think of many situations in which I would check/raise from upfront with a deep stack. Most of those include having poor players behind me that will allow me to a large portion of my stack in with a decent equity edge.
