I think you are getting too tricksy for your own good.

I'll say he calls with 88 and you take it down.

I would normally have raised pre-flop here, is that the right play? Raised around 100-150 or so, there's already a good few put into the pot, no one has rasied so I would assume I have the best hand (at this point) and raise. Although this could be completely wrong! If I had played as you did the K would have troubled me somewhat, I would prefer to make people pay to beat my starting hand then someone limp in with a 75s (to take an obvious example in relation to the flop) or even someone with 7Ks (the more likely hnad someone may call with and beat you with). If everyone folds pre-flop, you can take the pot there and then. I've only been playing a while though, don't take this as being correct, also interested in hearing others thoughts on my opinion?
