This guy is a complete fish/numpty.He built his stack chasing flush draws, hitting miracles etc etc when there where 5 players. Just me and him HU now and we're both deep stacked. I've been raising all my BTNs and C-betting them all, to which he's folded everytime. I've also 4 bet his BTN a couple of times and he's insta folded.

Approx stack sizes:
Hero : $140
Villain: $200

I get on the BTN and raise to $1.50
Villain flats
FLOP:

Villain checks, I bet $2. Pot is now $5.......villain goes mad and shoves.....

I'm putting him squarely on a flush draw.

normally i'd snap call, but we're both so deep....
