LO8 2/4 - Check raising

[Stoneburg]

I've decided to try and find spots to check/raise. I'm normally a PL or NL player (My "normal" game being NLT, PLT, SnG's etc), so my appreciation of when to use the check/raise in Limit games is limited (aha! A pun!).

This opponent has a tendency to float/sponge (at least I think so after seeing him do it twice), so I am fairly sure he'll bet the turn when I check whether he has something or not.

My instinct tells me to not do this unless I happen to pick up the nut flush draw to go with my nut straight as I did in this hand.

So... how about them check/raises?
