Bankroll issues

Having a poor run of cards at the moment, basically since the start of February so around $100 down this month so far. Lost about $20 of that in one pot yesterday and looking back I don't think I played it very well. I'm usually pretty good at spotting betting patterns but I don't know why but I missed this completely. It was the first hand i played!!!! So I was on the Big Blind. Q-7 off suit. Guy in 1st pos limps in, as does the guy on small blind. Flop comes Q-7-2 rainbow. I don't usually check 2 pair, only trips or higher, so I bet $2 into a $1.50 pot. They both call. I'm thinking one has a pair of Q's or 7's and the other the same or even fishing. Turn is 3. I bet $6 as there is now a flush/straight draw on and I don't want to get done on the River. Guy (now on button) calls and the SB folds. This is the point where I should realise I'm in trouble. There was no flush or straight draw on the Flop and yet he call my bet which was bigger than the pot, and has now smooth called the 3 on the Turn. Looking back on it, it's so obvious the guy has trips and its this kind of situation that I'm usually good at avoiding. Anyway the river is a 5 which doesn't make a possible Flush. There is a straight out there but it would have been an insider for $6 so I dismiss that. I bet $8 when i should have checked, and the guy instantly puts me all in, which is only another $3 so i have to call. He turns over Pocket 2's so he hit trips on the flop. Pretty unlucky to hit top two pair on the big blind and walk into a limper who hits trips; it wont happen very often, but still I felt I could have saved at least $8 from that pot on the river. If I had checked he would either have bet for value $4 or so, or gone all in which would have given me a chance to get away.

Well you live and learn I guess

Got a few big tournaments coming up soon. VC are doing a $100,000 freeroll but i have to beat 998 other players for the $24,000 first prize. Think it pays $200 down to 80th or so, so making the money would still be very worthwhile. They also have a $20 rebuy, with $20,000 added so I think this will be $60,000 or so total prize pool, with $16,000 going to the winner.

I'll be off to the World series in June if I was to win either of them ;-)
