re: Poker & €25 NLHE 6-max: OESD in 3bet pot, line check
Calling OOP is an option too!!
Like you say, oop pots get big and you rarely hold anything, and almost every turn card will be one you didnt want to see with small PP's
When you 3bet A4s OOP you fold out most Aces that beat you. If yiu hit an ace you dont expect to get the money in, so domination isnt an issue (unlike AQ)
You can C-bet bluff the flop, get called and spike an ace / the nut FD so you can barrell more turns. With 33, you cbet and get called, unless the turn is a 3 you are done or forced into bluffing
against a fairly strong range (he didnt fold to your 3bet).
Basically small PP's dont play well postflop.. and setmining in a HU pot OOP is also pretty bad.
With hands like 88/99.. call. Play some PF poker
