I have just, I feel, misplayed a live hand badly
At some stage recently "running bad" has turned into "playing bad" and I feel the need to be suitably chastised
Its the Wednesday night £50 plus £50 at Luton
3 tables are left, top 5 are paid, average for the final is 24,000
I have 12,000 and blinds are 200-400. I'm on an aggressive table, having just been moved there but I know all bar one of the players well
An in form LAG (Nav) limps for 400 in MP with 25,000 or so
Complete unknown in SB completes, but chatter around the table is that he is "clueless" and has got a 20,000 plus stack just recently with a 30-70% coup going in his favour
I'm in the BB with

and where normally I would raise here I think I 'll get called by a LAGwith a wide range with position and then have to play the streets OOP, I elect to check and if hit, trap the LAG
Flop

SB checks and I see known Lag look at his chips. Check raise time or weak lead? I lead for 800 into 1200 and sure enough LAG makes it 4000
SB flat calls immediately
Neither player can put me on TPTK here, LAG's range is wide and can include sets, 2 pairs, KQ, Qx, clubs or just second pair...I've seen him push people around with as little as that
He doesn't rate me, probably thinks I'll lay down most hands to a raise there
SB..no idea, but I'll take the risk he is behind me
I push in, with 10,000 in the middle up for grabs
Views please. Result irrelevant but please analyse my thinking
