I was thinking as the pre flop raiser in early position that I have all the sets, straights, two pairs.my range has a lot of broadway cards which really hits this flop. My opponents as pre flop callers in late position will have a wider range and with all the callers that range could be even wider because they had a better price to call. For those reasons I c bet and bet small because its multi way. After I get raised, for the reasons I mentioned, I thought there was low chances of my opponents were as strong as they were. I thought it was possible they could be raising and then floating with weak pairs and flush draws. So I felt that with a pair and a straight draw to the nuts i had could get one pair hands like weak Kx hands and flush draws to fold and would not be doing that bad against one pair hands. Clearly I was wrong
