I was playing a NL home game w/ blinds of 1/2, and it was nine handed. I had only $150 in front of me(not enough, next time I buy in for $200 min), and I was UTG with [Qh].
I decided to limp in because you can usually trap most of these players limping w/ any ace and betting it up, but also because I am not a fan of AQ UTG. Anway, the kid next to me limps in as well, then UTG+2 fold, and MP1 raises to $7. MP1(will now be known as LAG) is an aggressive guy who I have seen raises small pocket pairs and weak ace hands like A9 or A8. Guy after him calls raise(also an aggressive but poor player) blinds fold, and I call the raise and so does the kid (kid can be tricky, bets the pot when he has something which is respectable in any case, and seems to play well). The kid has $58(only bought in for $50), LAG has $240, bad player and I have $150. Pot is $31.

Flop comes . I check, and kid checks. LAG bets out only $5(?). Bad player raises to $10. I think for about 20 seconds and figure if I hit a 9 or K I will have the best hand against those players( I think LAG has missed and bad player has TP). So, it's a little over 2 to 1 to make my hand, and pot is paying me 4.6 to 1($46 pot). I can even ignore the pot odds of pot and still make a decent call here so I do.

All of a sudden, the kid wakes up after about five seconds of thought and checkraises another $25 to $35. LAG quickly folds his hand while bad player thinks about it for thirty seconds and finally calls the $25. Back to me, pot is now $116. And this is where I get all screwed up in the head...

I figure if I hit my king I am still good of course, but now I feel that w/ such a checkraise, the kid either has a set or the straight already and wanted to make the draws pay. I am getting the same odds to draw to my hand, but now I am fearful that if I hit the nine, I will only split the pot...so after about a minute, I folded. On the turn, a , kid went all in for his last $16, and bad player called...kid had Q9 for the flopped straight. Bad players was so embarrased he never showed his cards.

If anyone could help tell me what the EV of calling here would be, I would appreciate it because I don't understand how to calculate it for split pots easily without going into all the numbers here. I figure if I put the kid on the straight, my fold is really easy, but I would just like to see the numbers....because I am getting the exact same offer for $25 that I got for $10, 4.6 to 1 on my money and 2.17 to 1 to hit my hand(assuming all my outs are still live...which they weren't, of course).
