Another live 1-2 NLH game. I'm in the CO with 9s-7s. A MP player makes it $8. Another MP calls. The HJ calls. With four players in and good position I call with a stack of $172 behind my call. The Btn also calls. The SB folds and the BB calls. The BB is pretty loose but not super aggressive. I figure he could have almost anything. He has $79 back. The MP open raiser has only been at the table for about 10 minutes. He has $84 back and I really have no read on him but I figure he probably has me pre-flop just by virtue of his open raise, The other MP has $224 back. He has been involved in a lot of hands and has been really lucky. He could have almost anything. The HJ has $126 back. He seems fairly tight and I figure him for a pair or broadway cards. The Btn is capable of calling with almost anything here. He really plays the math and has $154 back. With $46 (I think) in the pot after the rake we went to the flop. It came Ks-6c-8s. BB checked. The MP open raiser bet $25. The other MP player folded. The HJ called. I have a flush draw but it isn't the nut flush or even very close and I'm open ended. I decided to raise here with $96 in the pot and 2 players behind me. I raised to $75. The Btn folded. The BB folded. The MP open raiser had $59 back. He shoved here. The HJ called and of course for $9 more I did too. Was my raise here a decent play?
