NL High draw 40 cards deck

Hi all

Iplay 40 cards draw poker with 5 or 6 players in private house.Its played with one and without blinds.It s a loose agressive game.

The buy-in is 300 E ante 5 E but increase after 1 hour to 10 than 20 E( usually after 2 or 3 hours of play).

I d like to know if it exist any probability about this game or any theory.

thanks

Don't play two pair.

Well it depends under which conditions as most of players draw to straight or flush draw they even open the pot with such kind of hand or sometimes even raise with it. I usually call in in late position or when i feel the open raiser in a blind is weak.
